Why this problem, for you?
The "why you" answer matters as much as the "what" - investors and your future self will ask.
Can you make meaningful progress alone in the next 90 days?
"Meaningful" = first users, working prototype, signed LOI, real money in.
What outcome are you building toward?
These have wildly different right answers for who to bring on.
How important is being CEO to you?
If both founders need this seat, it's a long-term landmine.
