Ask HN: Employee, Partner or Co-Founder?
This employee eventually transitioned to working on a lower than market rate salary in exchange for equity at a later date. Now, this employee doesn't want to be referred to as a "partner" in the company but rather as a "co-founder" because of an increase in interest and activity, though not revenue (yet), that has occurred as a result of them coming on board to handle business development (which my founder friend actually trained this person to do while paying them over several months).
So, to make a long story short. Would you consider this person, who drew a salary (albeit at a lower than market rate), was paid with company revenue since joining about 4-6 months after incorporation, and who has put no personal guarantees on company debt(s) but does own some equity a "co-founder," "partner," or simply "employee?"
If not co-founder, how does my friend get through to this person and explain why they aren't really a "co-founder" without causing unnecessary tension?
