Since the other individual, a friend, is full time; and goofy is still working elsewhere part time, it might make sense to get an agreement to gradually escalate goofy's profit sharing in recognition of what has already been accomplished. (Yes, we all know that this is counter to PG's recommendations on startups.) This will allow the founder to live successfully and make everyone eager to grow the company in the short term, and, as profits increase, then the developer can dedicate more time to the company and get more in return ... possibly abandoning the part time job eventually.
