In addition to the skills needed for each founding role (differs between teams) there are two vital things that have to align:

1. The why - if one of you is trying to legitimately change the world and the other knows up front they'd be happy to sell out for $x amount, chances are big problems regarding strategy will arise in the future, even if there never is a buy-out offer

2. Communication - I would rather work with someone whose 80% as good as the best available if their communication skills are better. Once you're out of the initial product development phase almost everything the founders do is communicating, on some level, whether that be managing employees, customers, or investors.

3.(BONUS) Growth mindset / Self-improvement driven - Starting a company means doing A LOT of shit that you don't want to. If you partner with someone that is afraid to be terribly shitty at something and won't even try, you're in for a rough time.
