I see a lot of people questioning who is a solo founder or not.

To me, a cofounder is someone who has enough equity to veto your decisions if they don't like them. Everyone else is an employee, whether compensated in cash, equity, or thank yous.

Most of the objections I see here are, "well, they had a support group of X and Y".

No one does it alone. The issue is whether you have ultimate authority (and therefore responsibility) for the success or failure of the company.

I'd say everyone on the list of solo founders was personally responsible for the success of their company.
