What's wrong with having one founder? To start with, it's a vote of no confidence. It probably means the founder couldn't talk any of his friends into starting the company with him.
I don't have many friends. I definitely could talk people into starting with me but I prefer maintaining control and direction of the startup.
Starting a startup is too hard for one person. Even if you could do all the work yourself, you need colleagues to brainstorm with, to talk you out of stupid decisions, and to cheer you up when things go wrong.
I hired a Personal Assistant that I get along well with pretty decently. I can build a team around me. I have just enough funds to hire a contractor for additional part time help.
I want to be a solo founder maintaining control over the startup with a team of employees around me. Is this bad?
