Did I just spent 6 months building a product that no one wants

1 points by harleenkh ↗ HN
For the past few months, I've been building a product "Linden". Its a low latency deterministic layer for ai agents. Linden helps businesses verify AI-generated outputs before they lead to real-world actions. It evaluates AI outputs against expected schemas, trusted data, and business rules to determine whether an action should be allowed, flagged, regenerated, blocked, or sent for human review.

Linden helps businesses ensure their AI agents don't just produce convincing answers — they make decisions that align with actual business requirements, verified information, and configured limits.

I have tried cold email outreach that didn't work. Published a professional demo across multiple platforms, drove 0 signups. Now, i don't know if I just built something that serves no purpose. However, when i was building this, i did a research, looked at a lot of articles talking about the same thing. If this problem exists, then why no one willing to try it out?

In general, if you won’t use your solution, and have no-one else asking for it beforehand, it’s not worth it.
There are thousands of these already, many have raised a lot of money. If your product and cold outreach is generated slop (as half your post is) it is doomed to fail. The easiest next step is to look at what your competitors are doing and copy them.
I don't get why you built it if your plan was to finish and theN do cold outreach. Why wouldn't you test the idea before and as you built?
I built MacroCodex and initially had zero users, https://macrocodex.app/

I didn't know how to get users, didn't have any marketing budget either.

Then one day, I woke up and realized we had 17,000+ users.

I submitted a "Show HN" to Hacker News and got "flagged" by GLP boosters; they simply didn't believe that our app results in guaranteed weight loss or gain within 2–3 weeks, despite having a Telegram community with 2,000+ members and a product with reviews. They reasoned "If it was this easy, why 40% americans are obese?"

Do not worry about people who do not believe, focus on ones who do and help them get the best possible results. That's what i did.

There are naysayers, but do they matter? Look at what they are saying is there any substance in that or any actionable advice? Use it to your benefit; ignore the rest.

What changed? I started talking about the problem it solves.

The average person will always think they can outsmart a "dumb app" So instead of trying to convince pro bodybuilders, models, or actors, I focused on beginners.

Beginners started seeing results, and those results got the pros interested.

Experts are often skeptical of new approaches until they see people getting significantly better results with them.

You don't need everyone to believe in your product. If it genuinely solves a problem, even the haters can't stop it from growing.

Your websites are sloppy, vague, generic. Sloppy in both the AI sense and in terms of quality. I don't know what your pitch is, whether you're offering a service or a product or what they are, or why you're worth picking over anything else.

It looks like you wanted to make a consulting website or something and then picked the most confusing, least compelling way possible to convey that.

Marketing is the hardest part of any product.

If you learned in the process, you can never say you lost the time

But you can always say that you just lost the game.
If that's your only goal in life, sure.
I was a commission-based salesperson at a SaaS company for several years.

Your cold-email outreach didn't work because it was probably also AI written. When I was selling, I would write super short, warm, personalized emails by hand that sounded like a human wrote them, and wouldn't use AI to clean it up. My response rate hovered between 0.5 and 1.5%. My coworkers would copy and paste Claude-written emails into Gmail, and their response rate was 0.005%-0.05%.

My biggest question, and this is not rhetorical, I'm genuinely curious for your reply: what was the problem that led you to build this product? Did you have the problem yourself? Did you talk to current and former coworkers about whether they were also having this problem?

The other people here are rightly pointing out that your description of your own product sounds AI-written and soulless. The way you overcome this is by passionately talking about the problem instead of the product :)

Did you talk to potential end users before you built this?
Okay, so if you build a product and don’t drive even one sign-up, it’s worthless to say that this is a product no one wants.

First, start posting on social media. Let people know what you’re building and why.

Choose your ICP and focus on solving the problems you’re supposed to solve with this product.

Now, check your landing page and its copy as well. Have you positioned it correctly? Because tomorrow, you could run paid ads, but no one will bat an eye if your landing page copy sucks.

For cold emails, write something short and concise. Explain the benefits customers get from choosing your product. Your ICP matters here because big tech companies or even established businesses might not use it, but a new founder or a new company might. So, try to focus on these.

Marketing is something you need to crack. My suggestion is to start writing LinkedIn content first, and do some basic SEO/AEO along with cold outreach.

Probably someone already asked, but I searched for the product on Google and didn't find it. SEO is still a thing, and for me it's the first thing to focus on, even before building the product itself.
Personally I think you have 2 issues, 1. You are early. This is something people will care about AFTER they get burned. AI adoption isn't quite there yet so you are solving a problem they don't have. 2. I have a background in marketing, I do not want to insult you but you need to hear this. I hate your website. I hate your website with passion. Your website will make people nope out sooo quickly. I'm not going to list the things that are wrong with it, because you need to take it out back, set it on fire, along with whatever demon is forcing you to make so many lists. I know that is harsh and I apologize for that, but if you want to do well you have zero chance with that website.
