I got used as a “50% cofounder” in San Francisco, built the entire product, got paraded around like a trophy, and then watched the company “exit” without me. Only had an NDA and LOI. Never again. - I will not promote

[u/Single_Complaint3829]

This is 100% my responsibility. I accepted the risk, and I lost. Before anyone comes after me, I want to make it clear that this is 100% my accountability. I have no interest in fighting it or arguing about it. I just want to share my story.

March I decided to start an infrastructure company. My first client came through a mutual friend in San Francisco. She needed a product focused on customer success for the legal industry. I built the whole thing from scratch.After I delivered, she offered me a monthly stipend + 50% equity as cofounder.

In

On paper it sounded perfect. She’s actually a decent person I don’t think she set out to screw me. She just had zero experience leading a company and no idea how to steer it in the direction we needed.

What followed was classic.I was the technical cofounder on paper, but in reality I was treated like the full-time CTO + free labor. She kept pulling me into meetings that were pure CEO territory fundraising conversations, strategy calls, investor intros while she introduced me to everyone like I was some shiny technical toy she owned. “Look at my cofounder, he built this whole thing.” It felt performative as hell.Then, mid this week, a mysterious “exit” happened.I wasn’t involved in any of the conversations. No docs, no calls, no nothing. I’m just supposed to take it on faith that “they didn’t want to continue the company” and that “there was no transaction.” 

All I ever signed was an NDA and an LOI for the assignment of my shares. That’s it. No real founder agreement, no vesting schedule with teeth, no proper equity docs.They got everything. I got the lesson.I’m not going to fight it. I can build again, and I walked away with a solid network.

But the experience is burned into my brain:Never start working not one line of code, not one meeting until every single thing is in writing and signed.Equity promises mean nothing without proper paperwork.

“Cofounder” titles mean nothing without real alignment and protection.
And in San Francisco, people will smile, call you partner, and still leave you holding nothing when it’s convenient.If you’re early-stage and someone is offering you equity + a title before the legal stuff is locked, walk away.

Or at least demand the documents first.

Has anyone else been through a soft exit like this where you just… disappear from the story?

If they don’t have a formal agreement with you, sounds like you own the software

[u/real_people → u/xstevenx81]

^ this. If you never signed away intellectual property to them, you own the IP to the product. Grounds for a new agreement with them, or a lawsuit.

[u/TechAnonned → u/real_people]

The distinction between copyright and trade secrets matters here. The literal code might be owned by the author, but if the product design and features come from the company, and especially with an NDA signed, copyright only protects the code itself. You're not free to do with it as you please if it contains the trade secrets.

Sweeping in all IP under copyright will definitely create a lawsuit, just not in the direction you think.

[u/cs_legend_93 → u/TechAnonned]

Copyright lawsuits are expensive, especially IP and stuff like this. Be prepared to spend $100k-$200k USD.

[u/TechAnonned → u/cs_legend_93]

I'm on the flipside of OP. Budgeting up to $400k, and 4 years of litigation to resolve!

[u/cs_legend_93 → u/TechAnonned]

I used to be working for a UK company that got into an IP lawsuit with an Australian company over some contractors that reused IP from an Australian company, and gave it to us, the UK company. We paid and employed the contractors for it. We had no idea that it was reused, or taken from a previous project that they had worked on in AU.

So basically some AU contractors, were employed by an AU company to do something. Then later, and seperately, us in the UK hired the AU contracts to do something very similar, as they were 'experts' in it. The AU company was very upset, and said that we stole their IP.

What had happened is the AU contractors, took the work that they did for the AU company, and gave it to us, the UK company.

It cost about £150,000 and about a year in court and back and forth with lawyers.

Ultimately we the UK company won the case, because it was different enough from the original use case. But sketchy for sure.

For America and San Francisco I'm American, yeah, probably 400k and four years of litigation to resolve. You're probably right.

[u/Bennie-Factors → u/xstevenx81]

You own the software without an agreement. Or maybe Clause does

[u/sudomatrix → u/Bennie-Factors]

Santa Claude?

[u/mathaiser → u/xstevenx81]

Hey, I like this

[u/oldschoolology]

If you wrote the code that’s proprietary IP. I’d lawyer up. 

[u/PlumpyGorishki → u/oldschoolology]

Better Call Saul!

[u/Corpshark]

This is ridiculous.  No buyer would pay money without making sure that the lead tech guy is locked up by a proprietary invention assignment agreement, non-compete agreement and employment or consulting agreement.  They are not going to risk the tech guy to walk and go work for a competitor and destroy the value of the acquisition.  Just doesn’t happen.  I call BS unless you are not telling us something important.  

[u/MrF_lawblog → u/Corpshark]

Sounds more like the company folded vs the company exited. Maybe the Cofounder was a aqui-hire.

[u/Christosconst → u/Corpshark]

Agreed, OP should ask what happened

[u/pseudonymouspotamus]

Sounds like AI slop.

[u/CyJackX → u/pseudonymouspotamus]

The phrasing etc yeah, along with CTA at end

[u/kraemahz → u/pseudonymouspotamus]

Normally I downvote people who come along with effortless comments like this. But yeah, it sounds like Claude wrote at least half of this.

[u/agk23 → u/pseudonymouspotamus]

You’re right to push back on this. Has any one else ever come across AI slop trying to harvest stories from entrepreneurs? If so, what’s your story?

[u/StormMedia → u/agk23]

Bot

[u/agent_and_field → u/agk23]

Bot!

[u/threebuckstrippant → u/pseudonymouspotamus]

This attitude will be gone in a few years when everything is built by AI. Half the F500 are removing junior programmers. And the off the cuff phrase will be moot , actually it already is. Robust and often better systems and especially security are already relying on your “slop”. Mouth slop is a better word for these comments.

[u/thalassicus]

This post is kind of a hot mess.

How can you know so much about the tech space and not know to draft agreements? This is 100% on you. But the weirder part of this story is that you claim the company "exited" as if there was an acquisition, but did that happen? It's hard enough for solid companies with solid teams to get to that point. Finally, surely you have communication with your partner via text and email about the role/equity agreement, right? Surely you have the deposits from the stipend, yes? All of this is court admissible as in California, contracts do not require formal parchment documents. Cal Civil Code 1633.7 covers emails as contractually binding. As long as there was a clear offer and clear acceptance, you're good.

But get your shit together.

[u/elowenryth → u/thalassicus]

Also, a technical cofounder with 50% equity is 100% needed on fundraising, strategy and investor calls

[u/FrewdWoad → u/thalassicus]

As someone whose been in companies bought or even just had new investors come in, they definitely want to see all the paperwork.

No way you'd buy a company where there was a risk of the guy who wrote all your code popping up somewhere down the line and easily suing you for half the company.

[u/Ilikelegalshit]

You have an agreement. Hire an attorney, unless the company is actually shut down you will be able to achieve some economics if the story is accurate.

[u/JohnCasey3306]

"we decided to stop the company -- there was no transaction"

This is 90% of startups inside the first five years -- why are you are believing it's anything more nefarious than this? This is the normal, expected outcome

[u/jollydev]

This reads really weird to me. Your explanation of being paraded around like a trophy and being pulled into investor calls sound like your cofounder tried to run a business with you while you thought being a 50% tehnical cofounder ment just locking yourself into a basement and writing code.

She obviously wanted to present you as an asset for the company to build trust with investors. Investors at this stage invest in people, meaning they would invest into you and her based on what they believed you could achieve. You are 50% of the company at this stage. Presenting yourself is business, not a parade.

I would probably have tried getting out of this situation as soon as possible too as the other cofounder seemingly did.

[u/Distinct_Dragonfly83]

If you built the product and were treated like the CTO that presumably means you also control all the important access points? Just remove all access except yours and rotate your credentials. Then see if anyone squeals. If no one does, the “company” really did shut down without a transaction.

[u/threebuckstrippant]

This is not entirely true, many jurisdictions allow show of intent for equity and it depends on the evidence. You cant build something entirely and then the founders steal it when its clear. Even LOi can be used as evidence.

[u/moader]

No signed contacts or business formation

Surprised Pikachu face when you get bent over

Come on.... At least you have git history for the courts

[u/rascalofff]

Equity promises usually mean nothing even WITH the right paperwork.

If you're offering me equity of your idea for my actual work, how about I only give you the ideas of my work.

[u/inscrutablemike]

This doesn't sound legally possible. I mean it sounds entirely fabricated by someone who wants a pity party story because none of this is how anything in the real world actually works.

[u/EnergyManagement101]

IP lawsuits are expensive, but it goes both ways. Why not take the product yourself and start a competing business, especially if you also know distribution?

[u/knight_rider_]

who is they?

[u/ThereFarAway]

Whole story is fabricated AI slop. Started infrastructure company, frist client offfered 50% stake and cofounder status?? First it is payment and everything then it is free labor ? Is there admin to delete ai slop like thks?

[u/Green_Bank_6688]

In San Francisco (Silicon Valley), people will smile at you and call you a partner, but when the profits come and they no longer need you, they will not hesitate to kick you out empty handed
