We're only getting your side and have no info about the history product team so it's tough to say. If you helped build product, there is traction or enough for for validation and the company has some actual deliverables; then you should ask for what you think is fair. Either way; I would start somewhere around what your salary was (or a completive salary) and then add a bit for risk. I would try and meet in the middle with equity or an earn out but people have different opinions. Maybe convert to debt; really depends what the company is worth, what you want and what the other 2 want...And what any legal forms / obligations are
