Was promised shares in a startup, worked 2 years and the day before registering the company got told I wasn't necessary
A psychologist from Warsaw wanted to make an app related to her field (she didn't even know what was necessary to make that, she had and still has 0 technical skills) I gave her advice, explained everything that was necessary, prepared the business plan, how much everything should cost, made promotional videos and wrote down all the nice to have and must have. When she finally found an investor (that has seen those videos and thanks to that she got the money) we started talking to an external software house that had to realize the app. I was present at every call, was even cited as CTO in many documents and the promised shares were 15%. Then an external guy came in and she had some kind of affair with him and they called me to tell me I never did anything (I have proof via mail of every work I did for them) and that I as CTO had to be below the COO (this new guy) and I wasn't gonna get any shares as I was more of a hired worker. I got mad and left the project. Past a month they call me to make me sign some document where I had to accept 3000zł (750$ LMAO) for 2 years of work and agree to never want to perform legal actions against them.
I said I wan't ok with that and they said it's all they can give me and that we worked together on that and I shouldn't ask for a payment as we worked simultaneously (wtf does that mean? Idk but whatever).
What do you advice? In this case I spoke to a lawyer, and have to gather evidence and write down the approximate hours of work I put into it.
Anyone had a similar situation?
(The day after I left the project they registered the company and my shares went to that new guy)
Can't tell more as I signed an NdA.
