I recently read a question on Reddit by an individual who was having difficulty finding a co-founder and asked whether she should first try to get funding, which would allow her to hire the team member that she needs. If you’re in a similar situation, my answer might offer a helpful perspective:
Investors look for the four ‘Ts’: total addressable market, tech, timing, and team. (I’d add a fourth T, which is traction.) Of those factors, my experience is that investors pay the closest attention to the team. Not having a single co-founder would put you at a tremendous disadvantage in that category.
