I sell my own books. I started in 2018. As of 2020, that made about 80 % of my total income.

Previous programming experience was useful, I could hack together some WooCommerce plugins that help me take care of the customers (generating invoices, communication with the Czech Post, pairing bank payments to orders and informing me about payments that could not be paired reliably). That saved me a lot of repetitive work.

What subjects do you write about? Any place we can look at your books?
Mostly popular history.

https://www.goodreads.com/author/show/18339067.Marian_Kechli...

Everything so far has only been published in Czech, though.

I’m surprised that you can live off of history books! Very cool.
Believe me, I was surprised too. Very surprised. The stereotype of a famished author is pretty strong here :)

Thing is, without middle-men (distributors, bookshops), most of the revenue accrues to you directly. Long live e-commerce.

I can imagine that you have built some sort of strong followers community to promote your books? I mean how do readers find your books?
I write quite a lot of (commentary) articles on my blog and some other Czech portals reprint them. This helped me build up a community of readers.
I started writing a popular history book a few years ago and found it really tough once I actually dug into it! Kudos on publishing so many and with such good reviews. Can I ask if you have an academic background in history?
I do not. It is just my passion since I learnt to read.

Around the age of 35 I realized that there was a lot of interesting and weird stories to share with others and I started narrating them in an online magazine published by my friend. For example, life and death of Hernando de Soto, the unsuccessful conquistador. (https://en.wikipedia.org/wiki/Hernando_de_Soto).

People liked the format and actually started to send micropayments. It still took several years before I actually tried to put together a book. I started a crowd-sourcing attempt which, to my (pleasant) surprise gathered over 300 per cent of the target sum.

Now I am hooked to the lifestyle :-)

I write content to help people settle in Germany. They need certain services, and I get a commission when I refer them to those services.

I don't think I could trivially reproduce the results, but I'm happy to get paid for offering free advice. I hope it lasts.

How much do you earn and is the space not saturated already? Are you expanding to new niches ?
The space isn't saturated, but there is some competition. However the quality is often lacking. I maintain a smaller set of high quality articles, and keep those updated. I also have a more simple, direct writing style, and designed the website for readability.

I considered expanding to other places or bringing other people on board, but I doubt I could maintain the same level of quality. Those articles require far more research and domain-specific knowledge than your typical SEO spam.

I'm also not that interested in growing. I want more time, not more disposable income. I am sitting on a few decent business ideas, and this website could easily grow to cover other countries, but I'd rather do more pleasant things.

> How much do you earn

About the same as I did as a developer, though it's hard to get a precise number since it varies a lot.

Where do I find your service? I am planning on moving soon.
https://allaboutberlin.com - I don't offer any services, only free content. However I do have a small network of trusted people I work with, if you need extra help.
I'm not planning to move but I enjoyed the writing style. Thanks for sharing and great stuff!
I've used this before! There's a wealth of great information here.
Im a dev who just moved to Berlin. Found your website and content IMMENSELY well done and useful. Breathe of fresh air to see how up to date the articles were. Made the German bureaucracy much more manageable tbh. Let me know if you'd like some user feedback on anything!
I'd certainly love feedback. If there's anything on your mind, just drop me a few lines. It doesn't matter if it's about the content or the website itself.
Thank you for making it
Wow!!, How much money you are making with this? How long it took you to build this? How you are marketing this?

Can you please give some advice on marketing.

Tip: for each artist or author you recommend, put their top books under the name with the picture from amazon and link there with an affiliate account.

An unfamiliar author’s name means nothing to me, but I might have heard of some of their books. And I’ll open tabs to check them out later.

For artists I’d love to SEE their pictures. I don’t know many artist’s names!

Agree with the artist comment. I input 3 of my favourite artists and got some recommendations. I selected "I don't know" because I didn't know who they were. Could just show the top 5 results from a Google image search for their name, or an image from their wiki page.
product explorer should ask what device you came from and set the minimum spec to match. It can probably pushState all the search params into the url so that these beautiful result sets can be shared.
Before I clicked through, I assumed the site was named after a backwards word.
A great many people [including myself] have a successful online business flipping which is buying and selling of goods (more used than new). Buying is from local thrift shops, auctions, garage sales, Craiglist, Facebook Marketplace, etc and selling is at Amazon, eBay, Facebook Marketplace, etc. If interested follow the Reddit sub-reddit: https://www.reddit.com/r/Flipping/
Isn’t this almost a zero sum game?
Yes. It is a lot harder to do than people make it out to be.
The juice doesn’t seem worth the squeeze.

I can’t even be bothered to sell my own used junk.

But it is a low tech way to do e-commerce.

I run https://www.checkbot.io/. :)

> Checkbot is a Chrome extension that tests 100s of pages at a time to find critical SEO, speed and security problems before your users do. Test unlimited sites as often as you want including local development sites to find and eliminate broken links, duplicate content, invalid HTML/CSS/JavaScript, insecure pages, redirect chains and 50+ other common website problems.

I created it to scratch my own itch while working freelance on other websites. There was one website in particular where minor changes on one page was breaking unrelated pages so a localhost web crawler that checked for issues was invaluable when doing small and large refactors.

The guide I wrote that explains all the page factors Checkbot tests for (https://www.checkbot.io/guide/) also helped me brush up on current web best practices. People treat SEO like a scammy word but the general recommendations are good for humans too!

Lunch Money (https://lunchmoney.app/) is run by one person. It is a personal budgeting app that is very well-designed and easy to use. The founder's journey is also quite interesting as she has been traveling as a digital nomad while building Lunch Money.
I wish they also pulled in brokerage account transactions
I wrote an OFX importer for Lunch Money just last week. Do the brokerage accounts support that?
Jen here– thank you so much for the mention!
Founder Jen is such an inspirational and helpful woman! Worth to follow her journey on twitter
I'll be starting a Youtube channel shortly about solo bootstrapping a tech business around a mobile app and everything that's involved, from idea validation to implementation, launch and marketing. Let me know if that's everything you're interested in
Could you share the business you’ve bootstrapped?
This will be a new business from scratch, built with the community. I'm thinking about using a sleep diary app I've already mostly built
I bet you could find some interesting guests in this thread. I'd be happy to share my experience, for what it's worth — feel free to contact through my profile.
That's a good idea thanks! I'll get in touch
I run a paid addon for local e-commerce platform(with 25k shops build on it). It all started about 15 month ago when i was still working in a web development company. The platform owners came to us and offered us a partnership. We would develop some new addons for them, run them, and split the profits(80% for us, 20% for them). As i was the one most interested in this i got the first project and developed and supported it for about 9 month. I saw it could have a nice future and bought it from the web development company and quit the job. Now i run it by myself and i love it.

The addon provides an easy way to print paper labels for products and other things listed in the shops.

Can I contact you? I have an overlap in interest ( I'm building an e-commerce platform and things are getting real :) )
yup, definitely, it's pdonat@seznam.cz
Did you have to buy out the web dev company you were working for? Did they not want their cut?
I bought the addon from them. They wanted to run it however since i developed most of the app and supported it they would have to train new person for it and dedicate his/her time to it and nobody wanted to be that person.
https://hauling.market/

Andrew is killing it. Already over one million in bids on his platform.

This is super unique, really cool to see.
I think there was a TLC show about this industry and how they negotiated their routes and stuff, really cool project
This is interesting. The copy on the page is pretty broad (beyond this single spot about horses and all small animals), suggesting they accept any type of shipment. However, when you look at the request they are almost 100% horses or other small animals. I wonder if the founder should niche down and focus on the animal market, seems like there is demand.
He runs at least 8 Facebook animal hauling groups, so he's well acquainted with the niche. His mom started the horse hauling group many years ago, and Andrew took over.
I feel like the question is wrong.

I used to run a profitable one-person online business. And I felt miserable every time I had to get up at night to fix server issues, or when I had to do customer support from my laptop while I was supposed to be on vacation instead.

Now that we're a team, I feel so much better about the whole thing, even though profit margins are slightly lower than before.

(comment deleted)
I work for a large ISP as a software dev and still have to wake up at 11am to fix server issues, I also got called to fix something on Dec 31 while I was on leave. I'd rather be working after hours for myself than for my a-hole boss
While I don't know your usual sleep schedule, waking up at 11am does not sound too bad to me.
I know quite a few people who answer emails on vacation and who do on call rotations at their "normal" jobs. So I think part of the appeal of these types of questions is that the individual gets to reap the benefits of their extraordinary effort instead of passing the profit upstream.
What is your business can you please elaborate. Its fine. You started with 1 person thats great accomplishment to have team.
https://pageflows.com has been paying my bills for a couple of years now

To give you an idea of revenue, it’s about as much as I’d be getting paid as a junior-mid developer in London and requires a day or two of work a week unless I’m adding a new feature, redesigning etc.

https://screenjar.com is also making a small amount of revenue, but nothing meaningful yet.

Screenjar looks very cool. Great idea! Bookmarking for later use
Brilliant. Are all those screenshots and videos made manually? Hard work
Yep - I've looked into automating or hiring this out, but spending Monday every week updating/adding a product has been the simplest solution so far
My former employer's support department uses TeamViewer with customers. A web-based equivalent would be a game changer for them, if you can go real-time.
Thanks for sharing, screenjar looks interesting. I'll try it out in a few days.
Awesome, thanks - let me know if you have any questions or feedback
I've run my own one-man[1] software business selling desktop software for Windows and Mac since 2005. Products with launch date:

https://www.perfecttableplan.com (2005)

https://www.hyperplan.com (2015)

https://www.easydatatransform.com (2019)

2020 wasn't a great year due to the effect of COVID on PerfectTablePlan sales. But I've been profitable every year.

[1] With a bit of help from my wife on the accounts and freelancers for web design, testing etc.

Really tiny comment, but I noticed on Perfect Table Plan you have an example seating plan for a lodge with peoples names? As a member myself I know there are quite a few people who prefer to remain anonymous, so not sure if they'd like that image to be up (albeit the risk is very very low that they'd be identified from a table planning app!).
Any names you see in seating plans on the PerfectTablePlan website are ficticious.

BTW the fact that the seating plan isn't stored on a third party server is a selling point for privacy minded users/organizations. Particularly when it comes to politicians/royalty/celebrities etc.

I used to read your blog back when I was into shareware. What a trip down the memory lane. Glad to see you are still in the biz!
I run BeeLine Reader, [1] which launched on HN years ago. [2]

BeeLine makes reading on screen easier and faster. At first, most of the revenue came from B2C mobile apps and browser plugins, but in 2020 it hit a tipping point and most of the revenue now comes from B2B technology licensing.

Blackboard recently adopted the BeeLine technology, and there are several other large education platforms that are planning to adopt in 2021.

Licensing revenue is uncommon for startups, but it's nice because it's very high margin. I actually used to be a lawyer, so I can keep the main licensing cost (legal fees) under control.

What a brilliant idea :) Plus I like the name, it very nicely summarizes the product.
Glad you like it! Happy to send HNers a monthlong free pass — I'm nick@[domain].
What makes licensing possible -- do you have a patent? Reimplementing by a competitor, at least at first blush, seems like it might be feasible?
Yeah, patents. But many licensees are also just happy to have use of our JS, and to be able to use the name. The name has decent recognition in assistive technology circles and is gaining traction in among university students as well.
Homepage looks a bit funky on iPhone SE (2016) https://i.imgur.com/QcaZVx8.png

I see this sometimes and then zooming out gives me the full view, but it's already zoomed out here.

Great idea btw!

update: Also checked on desktop, the site transfers 8.5MB and takes 13 seconds to load (the gradients). (My download speed is 7MB/s.)

Thanks for letting me know — I actually have an old SE lying around so will test this and see if we can get it to behave better.
Beware of the selection bias before making any conclusions.

For every person who currently does X successfully, there will be a multiple of those who failed at the (nearly) same and aren't chiming in.

Well, but that is the idea, the selection bias is in the question not in the answers. He is not asking what % of one-person online business are successful.
Sure, but this renders most of the answers useless. Interesting, entertaining, curious, but useless.
Not at all. That's how people have learned to do stuff for thousand of years, you copy the successful cases.
I think that what OP is saying is that copying the successful case will not make you successful - otherwise everyone could be successful after reading a few discussions like this, or reading millionaire's books about how they became successful.
> otherwise everyone could be successful after reading a few discussions like this, or reading millionaire's books about how they became successful.

None of those things are actually copying, arent they? They are just reading.

Do I believe that everybody who actually creates a small SAAS emulating some of the ideas presenting here will be a smashing success? Of course not! Do I believe many will succeed? Of course!

This is like saying, how do I get to the NBA? Well, train hard everyday, eat well, get into a competitive basketball program since HS. None of those things are sufficient, but for sure are a great blueprint.

Correct - I run two Saas apps. One collects COVID symptoms from kids attending childcare centres and the other allows users to send SMS from Google sheets. I've made a total of $5 from both (first customer for SMS tool last month).

I had a lot of interest in the symptom screening tool, but then my provincial government changed the rules so child care centres didn't need to collect symptoms. I have 2 centres using it and I just cover the bills. I've told them they can use it for free. Probably more of a hassle to collect the $10/month from them.

Selection bias, it turns out, is built right into the title of the post. Also, a hard-won concept I have learned in business is that it’s much better to learn from people who were successful than from people who weren’t (not trying to be arch or facetious here).
I license a fully automated UV unwrapping tool at MinistryOfFlat.com . UV mapping is the task of unwrapping a 3D model to a flat surface in order to put textures on it. Ive been at it for about 3 years, and last year I made 7 figures. I do sell directly to 3D artists. You probably know some VFX companies and game companies that have licensed my tool.

I make a good amount from people coming to the web site, but the majority is made licensing the technology to various companies. The online sales are mostly there to spread the word, and gather user feedback.

UV mapping is a very difficult problem mostly because artist have very specific ideas of what constitutes good UV mapping and it doesn't conform to any simple heuristics. Its about a megabyte of C code without any dependencies, and that makes very attractive to licensees.

That’s really cool.

Do you worry about licensees keeping the code and using it without you knowing if they cancel? Or an employee at a licensee walking off with the code / binary etc?

We’ve talked about some of these risks at my current job which ships code as our product so curious how other people navigate this.

Congrats on the success!

Thanks!

First of all I sell perpetual licenses. For everything else I rely entirely on the honor system. I wont spend my time chasing some student who pirates a copy. The real money comes from the larger companies and they are terrified of getting in legal trouble for breaking any kind of license agreement, so they have no reason to screw me over.

I worry a lot more about making things complicated for licensees then I do about them taking advantage of me.

Love this! I wish more would share your take on this.
dude is obviously a fing genius and probably has calculated that its more worth his time playing in the stock market than tracking down legal cases.

glad to see a software guy use all the modern day tools to get out of the rat race. cheers

Thanks!

Its also much better for your health to focus on helping people who support you then, to worry about what a few bad apples might do without you ever noticing.

Congrats! I’ve meant to ask you/Brent: what do you think holds ptex back in VFX and animation?

(For games, it’s clear that ptex is basically a nonstarter, since GPU texture mapping hardware can’t / won’t deal with it)

Lost of things. Lack of tools is one. Lack of hardware is another. Its incredibly useful to use 2D images as resources since there are so many tools, file formats and pipelines that support it. I have always seen Ptex as "UVs are hard, so lets reinvent everything to avoid solving that problem". Since I have solved the UV problem, there really isn't a need for Ptex.
Congrats! Sounds really amazing and great to see commercial success too!
That's really cool. I have really hard time calculating the prospect price for commercial usage of software. can you share the average commercial license pricing range for a product? and how much does it differ from pricing for individuals? Thanks for sharing your stats.
Divjoy [0] is now profitable and my full-time thing. It did $50k in year one and my goal is to break $100k this year. It all started with a Show HN [1], so thank you HN :)

It was rough going at first, but I won the $15k YC Startup School grant [2], which let me jump into it full-time and give it my full focus. I managed to hit ramen profitable before having to go back to freelance.

The conventional wisdom is that devs won't pay for software (especially code!), but I've found it to be the opposite. There are a lot of employed software engineers who have disposable income and who are happy to pay for a dev tool if it means they can actually build and launch an idea in a weekend.

Its amazing! thanks for sharing. Can you please tell from where you are getting the users? How you got your first users and what you are doing for marketing?

Thanks a lot.

My first batch of alpha testers came from a single Twitter reply [0] that got retweeted by a prominent person in the React community. It certainly helped that I had an okay Twitter following at the time (I think around 1k), but it doesn't need to be huge. You just need the right person to retweet you.

That was enough to iterate on until I had an MVP.

Then my Show HN [1] sent like 15k visitors in a day and that led to a ton of usage. I think something like 4k projects were created that day. I wasn't yet charging at the point, but probably for the best, since high usage meant a lot of feedback.

A few months later I launched on Product Hunt and that went well [2]. Beyond that, just improving the product every day, sharing my progress on Twitter, and trying really hard to turn every new feature into an exciting launch event.

I also started a React hooks blog [3] that sends me a handful of customers every month. I could probably do a better job of promoting Divjoy on there.

Haven't delved into SEO (barely rank for anything), content marketing, paid advertising, etc, so it's still very much a learning process for me.

[3] https://usehooks.com

How do you get visitors to the React Hook blog when you're not investing in SEO. Really curious.
The blog ranks really well without any special effort, but for Divjoy I haven't put in the work of setting up extra landing pages to rank for different topics. For example, I'd like to have a page like divjoy.com/nextjs+stripe that emphasizes that stack combination.
I've been looking for something like this for ages. I have a small project I need to do and I'm not really a web developer. Muddling through setting all this stuff up for the first time would be far more work than the actual website.

How hard would it be for me to integrate with Authorize.net?

I'd say that if you're interesting in learning to code then Divjoy may work for you. I try not to over sell it to non-devs, but I do have a fair amount of customers who are hacking at Divjoy projects while learning to code and are very happy with that.

Since all the boilerplate works out of the box you can skip over a bunch of stuff (like understanding how auth works under the hood), but generally there's some custom logic you need to write and you'll want to pickup some JS/React to do that.

Any integration with Authorize.net would be totally done by you. You could export a codebase with Stripe payments so that you can at least see how payments logic ties in with UI.. but you'd need to then strip that out and replace with your own custom Authorize integration.

Oh, I'm a SW engineer. I just mostly worked in process control and consumer electronics. I've done a few websites.

Thank you for the reply. :-)

Gotcha! Then it shouldn't be too hard to integrate Authorize. UI is mostly decoupled from payment logic. Always happy to hop on a call if you need some help understanding anything in the codebase.
As an addendum... Purchased a copy of your thing, looking forward to exploring it. I'm reasonably clever and I don't expect I'd need any help, but I super appreciate the offer.
Thanks for buying! Once you give it a try I’d love to hear any feedback you have or requests for new components/integrations.
I also suggest using frontendor.com, it'll help you build a beautiful HTML interface for your website by copy-paste.
Would be cool if you could add Plausible Analytics!
I've been meaning to look into that. At the moment I'm using this library as the analytics abstraction: https://getanalytics.io. I'll see if the Plausible team wants to create a plugin or do that myself when I have time.
I’ve been chatting to Marko via email and they seem very approachable!
Looks like they don't have time, but there's an open issue here: https://github.com/DavidWells/analytics/issues/96. I probably won't have time for awhile.. but on the off-chance you're interested in tackling it, I'd happily hook you up with a free Divjoy account in return ;)
I just wanted to say that I really appreciate the decision to have the first steps of the project customization process not require registration let alone payment. It makes for a better sales pitch than a hundred landing pages.
Thanks, that's great to hear! I'm not a fan of having to signup/pay to see how an app works either. Figured a tech audience would appreciate that.
> There are a lot of employed software engineers who have disposable income and who are happy to pay for a dev tool if it means they can actually build and launch an idea in a weekend.

This is absolutely true, but companies also, or even devs working in companies will buy out of their own pocket to improve their productivity without having to ask the Accounts department, I know I have!

That's a really good point! I may have a good number of those customers and not be aware of it. I need to do a better job of asking people what they're using Divjoy for.
Hi, I wonder what payment stack did you use? Is it only PayPal or do you use other, too? I'm thinking of integrating with PayPal API, too, but really didn't know the steps needed (not really friendly compared with Stripe)
For Divjoy I'm using Stripe and PayPal (one-time payments). In terms of the code I give customers, I'm just doing Stripe subscription billing via the hosted Stripe Checkout page.
Hi, wanted to let you know that when I click on "see pricing" on the banner in the top of the page, nothing happens. There's no way to find pricing at all, since there's no link at the bottom of the page either.

I'm using Firefox 68.11 for Android.

Thanks for letting me know! If you scroll down below the "Choose your template" section do you see a pricing section with purple background? I'm wondering if the scroll to logic is broken or if that section is just not being displayed. If you wouldn't mind shooting an email to gabe.ragland@divjoy.com I'd love to follow-up about this.
I develop Cursive - https://cursive-ide.com, a plugin for Clojure development in IntelliJ. I started working on it seriously in 2014, started selling it in 2015 after about 2 years in beta (during which time I had a daughter) and it has provided all my income since then. The sales are more than my salary + bonus (but less than total comp) at my last job at Google. This year is the first year that sales have dipped slightly, probably due to COVID and a better competitor for VS Code, but it's still very profitable.
Thank you for making. It makes learning and writing Clojure fun !!!
My pleasure, I'm glad you enjoy it!
I had many un-used domains I've purchased over the years (>40) and I wanted to make use of them without having to spend time, so I built Newsy - launched 9 months ago.

https://www.newsy.co

It turns your un-used domain into a Reddit-like content aggregator with all sorts of features - membership, voting, comments, newsletters and monetization. The best thing for me is that it is completely automated and all of my domains are hosted on the platform. :) Not Ramen-profitable yet, but pushing it to get there.

Great idea! How much does a typical unused domain make using this?
It varies.. some ad platforms are quite poor in terms of their payout (definitely not in AdSense league), but we are working on various features for more monetization options (e.g. direct advertising)
How you got these approved from Adsense? Heard that usually have issues with content aggregators claiming such sites do not have original content.
Some sites have already been approved prior. We generally discourage our users to apply for AdSense initially (most likely it'll get rejected anyway) - so instead we recommend using other ad platforms (there are plenty).
I couldn't PM you via your contact details on HN. I can help you with this. Is there a way I can message you?
Sure thing! hello@newsy.co look forward to talking to you!
Can you share Adsense alternatives that can actually have steady payouts?
I run adhaste.com and you can send me a message if you want to try it out
This is pretty cool. I just logged into my namecheap account to see if I have any random names that might work. Unfortunately all my names are fairly specific and probably don't get any organic traffic nor are they well suited for aggregators I'd say. Just followed your Twitter account, I'd really love to see success stories.
I have a plenty of niche domains too and I try to gather contents focused around those niche areas and it's been awesome to see people flocking around those contents! (potential future users?) :)
This looks really cool. Will be considering for some future projects. One thing that immediately occurs to me is that I’d be concerned about vendor lock in. I wonder if you could offer a fixed fee “eject” option if I want the ability to go off and do my own development on top of what you give me.
Well, vendor lock-ins are everywhere almost right? We can allow some data export, but currently this isn't available - not necessarily a feature frequently asked for either, so we don't really have an immediate plan for this yet.
The dataloco example website is broken for me
Close Tools [1] is run by one person and they're currently at $40k MRR.

I was listening to My First Million podcast the other day and they mentioned a product that was specific to Poshmark, I wonder if this was it. They went on to talk about getting in early to platforms and making a killing (ex. when FB opened their API, Shopify marketplace, Google Ad words). Poshmark seems like a giant service that likely has a lot of area ripe for development.
Yes, Decentralized Finance (DeFi) has been very lucrative

Basically its great because everything is client side so all you have to is make frontend websites for people to interact with, and even that isn't really necessary. You just need people, with wallets, to be able to interact with your smart contract easily.

The smart contract you deploy has to address a pain point for existing users, typically by consolidating multiple transactions they are doing into a single transaction.

Your smart contract can take a cut of the transactions that flow through it.

The ongoing overhead costs are practically non-existent. The initial costs to deploy your smart contracts can vary to be several hundred dollars at time of writing.

It doesn't really matter what people think is happening in the blockchain space, or their infinitely moving goal post to reinforce their view about a lack of use case. The reality is that there is a market and there are market needs, just like any other market. The distinctions in this space is that the payment system is built in and all the users bring their own connection to the nearest servers which store all your variables. It's not different than any other financial services, just way faster and permissionless to get a foothold in.

Is there a way I can contact you? Interested in learning more.
vmception00 [at] gmail [dot] com

I don't check it, but I'll try

I would like to know more about the subject. Is there any way I can contact you ?
vmception00 [at] gmail [dot] com

I don't check it, but I'll try

So what's your business exactly? Can you be a bit more concrete what your smart contracts are, what problem they solve?
My specific business? Hard to say because it changes every week as there is really just that much to build

If people find getting into interest bearing products to be complicated, then you would create a contract to make it less complicated.

Pooltogether.com is an example of something people like, I didnt write that. It just gives people a chance of earning more interest than they could alone, at the expense of earning no interest in the mean time. They bill it as a “no-loss lottery”, while it is really just helping people deposit into other onchain financial services. It is analogous to many people depositing into a single savings account to earn more interest than they could as an individual, and only one person getting paid all of the interest. So some people like doing that because their alternatives are non-existent.

You can make a competitor to that or something slightly different and get people using it.

How do you audit the security of your contracts?
Unit tests like normal software development.

I don’t post or advertise audits, third party smart contract audits are expensive and purely a marketing racket.

A) users dont care

B) Vulnerabilities come from closed source pricing oracles.

C) users that do care understand that vulnerabilities are not really coming from the code and more so from pricing oracles

D) Users can buy smart contract insurance.

E) They can also buy their own smart contract audit, I at least make sure the block explorer has the code and ABI available

With all due respect, I think you're off on point C. There are a plenty of vulnerabilities as a result of code issues. Look at the great work that Trail Of Bits (no affiliation) has done in this space and you will see some great examples. There are a few folks that do solid audits, thought you are right there's no guarantee and it's expensive.

As to your point that user's don't care, I think that's the real answer, and it's a shame. Do you think the user base is not technical enough to care?

Sure, so first what I avoided saying is that plenty of code has intentional or unintentional backdoors and nobody can ever tell the difference of intent if those backdoors get used. It is a sad and risky part of the space for the users, but doesn't undermine any point I made about how the developer makes money. It does undermine how comfortable a publicly facing developer would want to be. Even if the developer does get vilified publicly and professionally or actually incurs some legal liability, they can still just change aliases or release more autonomous code under a new pseudonym. Either way it really amplifies their - or some other developer's - earning potential. And users can also buy third party insurance (which is its own sector and has its own growth challenges).

Secondly, another thing I was alluding to is that you can just copy working code. You can deploy the exact same service as someone else and compete directly. Too many developers think they need uniqueness, which may have been true in the "I can only get recognition from VCs to make real money" world. DeFi development is analogous to launching a grocery store offering slightly different brands. The code you copied from having already been audited.

Third, everything I wrote before was assuming no malicious intent. So if we are copying code for the most part, it moves the vulnerabilities to the closed source oracles and the behavior of the oracle's sources of data.

I'm always open to having this conversation, in general top level hackernews has not been ready for that conversation and they want to debate largely irrelevant things about their feelings over blockchain, as opposed to the state of various sectors in the space that they aren't aware of. So leading with nuanced discussion would hurt the visibility of what I actually have to contribute.

Cool, I hear ya and I agree, I wish there was more nuanced discussion on these topics rather than just "hodl, numbers go up."

It seems to me like you've found an interesting way to play in an adversarial space by selling shovels during a gold rush.

With so much noise in the space, how do you attract awareness to your contracts? And how do you manage the community?
do traditional exchanges work through smart contracts too?
DeFi is really great for entrepreneurs yes: lots of curious users, lots of money in it, lots of VCs, can build on top of other projects without permissions, and no regulations.

And with crypto prices going up we are probably going to see the next DeFi bubble.

If you want to build a DeFi app, You need to learn DeFi development and I have a course just on that: https://eattheblocks-pro.teachable.com/p/defi-development-ma...

I also have a youtube channel for blockchain dev: https://m.youtube.com/channel/UCZM8XQjNOyG2ElPpEUtNasA

For a developer who has no idea about blockchain, how hard/easy is it to get into DeFi?

Also, do you think this can be a long term career?

DeFi is easy and doesn’t really involve blockchain knowledge, but your use of the code becomes blockchain knowledge.

The programming is all javascript and solidity, which has syntax very similar to js. The blockchain imposes restrictions on how complex your code can be which means you are writing simpler code. More like building with legos (which is very similar to other programming where you have dependency hell, not really prevalent here because the other code-legos don't really change).

Private sector has not gotten around to valuing this skillset and typically interview out of novelty and curiosity but are completely confused and ignorant about what your involvement in “blockchain” actually was, but there are enough VC backed companies that operate in this space if you wish to eventually be employed.

You can also get wealthy enough not to care. Not from crypto prices rising, just from transaction volume and earning your crypto.

"just from transaction volume and earning your crypto."

Could you please elaborate? Do you mean taking a cut from the transactions?

Also, if I gave myself 6 months of part time study, will that be enough to get proficiency to start working on real world projects?

> Do you mean taking a cut from the transactions?

Yes.

> Also, if I gave myself 6 months of part time study, will that be enough to get proficiency to start working on real world projects?

Yes.

If you already know how to program it honestly won't take you that long. The bigger issue in DeFi and crypto in general is what to focus on. Here, all of your side projects can make money right out the gate without trying to look more legitimate than the next, but now some make more than others. The space moves extremely fast and other people's better ideas can be tempting to focus on.

Thank you for taking the time to reply. Checking your course
You are not replying to the person with the course right?

Because if so i would be skeptical.

People selling courses are selling the dream and hyping "money making" through some new shiny tech.

I hope these two accounts are different persons.

I created AuctionGo (https://auction-go.com) about 18 months ago and started getting traction really quickly through Google Ads. It’s white label auction software (like creating a private Ebay of your own). I had envisioned many medium sized businesses in the US would use it to sell commodities or host reverse auctions for suppliers, but all the interest has come from overseas companies selling all kids of things, especially real estate.
OptDuty [0] is ramen profitable in my place (like $1k per month) after 4 months from launching. Although it's still side project for me.

Everything started from a Show HN post and one comment on HN. Majority of paying clients are from HN too.

I started the project in May, and launched in August. And after 2 months I was thinking it's total failure, because target audience is too specific and my marketing skills sucks.

But by keep talking to a few early users I finally managed to convince them to use the product and than paid for yearly subscription.

I'm running https://info-beamer.com, a digital signage hosted service using the Raspberry Pi. It started as a for-fun project 8 years ago when I decided to do the digital info system for a local hacker conference and didn't find anything that allows quick prototyping and rapid iteration/live coding of content. I then switch from "desktop Linux" to Raspberries and added a web based service around the fairly low-level command line tool. It's my main source of income for 4 years now.
Excellent product. I've been testing it out and find very useful - especially dual-hdmi support.
https://profunctor.io/

Job board for developers with cross post to popular Telegram channel. Might come in handy if you hire devs and don't mind to work with people in EU Timezone. Job posting is free of charge.

I made some money with ads last year, tho.

Моя кошка нашла тут работу, спасибо
Not your personal army.
Another sink where the recruiter will get you... No thanks, I'm fine with having a LinkedIn(and never opening it).

This website is a complete shit. Especially that "Login" button.
Я js-макака. 3 года искал работу пока не наткнулся на охуенные мемы и вакансии от Profunctor. Сейчас вообще похуй куда устроится, залетаю на совбес, лид смотрит презрительно а я ему сразу мемы насыпаю, оказался норм штрихуля, hr-шу нахуй послали и ее зп мне на бонус кинули. Вакансии заебись. От души, рекомендую.
Как же я ору с коммента ниже
OP asked about successful businesses. It is not even a business. Something like a pet project idk.
