Dear HN,

My co-founder (who is a close friend) and I have been working on a startup for about 1 year now. My co-founder had the "idea" for a startup. He needed a programmer, so we joined forces. His role is supposed to be design (though currently the application uses my design) and sales/business development/marketing.

The product is 99% complete and could be launched in a week. Unfortunately, we can't agree on partnership terms and ownership of the company. My co-founder wants 60% of the company and refuses to split the equity equally with me. My attempts at discussing/negotiating this with my co-founder only stir hostile, belittling responses from him.

I've often felt bullied and mistreated by this person, who treats me like a "resource" and bosses me around like a child. Though in certain stages of the project my co-founder has contributed significantly to mocking up the user-interface, we've gone through many iterations and, currently, 100% of the design AND code was created by me.

It's looking like we are about to go our separate ways, and my he is threatening legal action and asking me to sign an NDA.

He is not trying to take my work. He wants to start from scratch again by finding a co-founder or hiring a developer to build his idea. The thing is, I'm still invested in my product. I don't want to ditch it.

I haven't signed anything up until now. I think my co-founder registered an LLC, but we've never agreed and signed any sort of partnership/ownership/nda agreement. What power do I have in this situation? Could I find a new non-technical co-founder and launch my product? As a last resort, I would even launch my product for free so my co-founder does not find another poor technical co-founder to abuse. I feel very cornered right now.

I've spent over 1200 hours designing and developing and have a very strong vision for the product.

What can I do?

Thanks in advance, HN. You guys are the best.

* ONE SUPER-IMPORTANT FACT I FORGOT TO MENTION * My co-founder does not have access to my code. I've suspected a partnership breakdown for awhile now, and since I haven't signed anything legal, I decided to make sure all of my work stayed out of my co-founders hands. I've never signed any agreement. I haven't been paid a penny.
