So there was no expectation set on the 1st day. The first and 2nd month or so - was still determining our product-market fit. The 3rd month was more aligning to clients.
However, its clear the value I set for the team behind the 3 month acceleration process. And that now, if they lose my contribution, the whole startup would be set back. (granted thats my perspective)
My point is you should have a talk with them and find out what's in their head, before you go all "I think I deserve..." There is no better time then now if the project is at a critical junction.
Simply ask what expectations you should have from them employment/equity-wise. How do they see me folding you into the firm. Don't let them put it off and get an answer, within a reasonable time.
Don't make it combative. Find out what they are thinking... digest it... tell them what you are thinking... let them digest... and come to an agreement... or not
