Technical co-founder, built everything. Offered 4%. Oof

I wanted to share a cautionary tale and get your take:

Note - I had AI help me turn my billion-page story to a reasonable length.

I understand I was naive in this, but I was trying so hard to do my best work that I didn’t look at the whole situation objectively. That’s on me.

The truth is, no calculator or startup blog can account for all the variables in a situation like this — execution, risk, emotional labor, trust, money, time. So I’m turning to the real-world experience of people here. Appreciate any thoughts.

I spent 7+ months as the technical co-founder on a startup. I built everything — backend, frontend, auth, UI/UX, integrations, hosting. There was no product before I joined, just an 8-year-old idea (yes, I know) and some outdated PDFs (just designs). I also paid out of pocket for tools and brought in a second dev a few times to help with tedious work so I could focus on core functionality. I spent money while they spent zero, so I could, now in hindsight, make their dreams come true.

The non-technical founder, who called it their “baby,” legit contributed no money. They didn’t want to earn income due to low-income housing restrictions… They wouldn’t even set up a Google Workspace account for a proper email. There was no business plan, pricing model, Stripe setup, or legal entity. Just a 30-ish person waitlist from a year-old landing page form and vague claims like “some people said they’d use it.” However, before a company was formed or a product was launched, they somehow sponsored a fundraiser and the logo of the “company” was put on the event’s marketing materials.

Despite all this, I stayed committed. Even though they initially said 50/50 would work, I realized it probably wouldn’t work out in the long run and that I’d end up taking on more than 50% of the work for the company. I told them they should get more equity because I might not stay forever, but I wouldn’t leave them in the lurch. I’d get it launched, help with transition, and do things the right way. I just said, “we’ll come up with something fair.”

When it came time to formalize equity, I got a “final offer”:

– 2% equity with possible reimbursement for expenses later – or 4% equity with no reimbursement and no recognition as a founder

They said anything more would “scare investors,” based on free advice from an accelerator/startup lawyer. I had done all the work, paid for everything, built all of it, and now wasn’t considered a real co-founder even though I did co-founder work because I might leave at some point, but wouldn’t leave them hanging.

There were no deliverables without me. There was no code, no UX, no logic. I hadn’t launched it yet, so I walked away and kept the code and IP (they have never seen a line of code and didn’t have access to my repo).

A few days later, a barista at the cafe I used to work from told me they were building a similar product (so, clearly it was a novel idea…). They and their co-founder already had 200+ signups after having a landing page up for a week, were paying their developer, had Stripe in place, and dozens of internal docs. How was the barista paying for their product to be built, you may ask: by taking a second job as a barista. They made it work.

That moment really drove it home: I had confused generosity with partnership. And that line turned into exploitation. The whole thing has made me hesitant to look for a co-founder for the project I’m currently building.

So here’s my ask:

– Have you dealt with similar founder dynamics? – What would you have done differently to protect yourself if someone had an idea you believed in, but they couldn’t afford to pay for any legal fees? – How do you vet a potential partner? Yes, it’s business, but does it have to be so “hardcore” with everyone? Or was I in a weird situation? Or just dumb? – Is it possible to partner early without formal agreements that feel adversarial?
