I think this really depends on what you are personally bringing to the table. In my experience, to build a successful business you need someone who's really good at sales, someone who's good at building and someone who can prioritise things correctly.
If you get lucky, you can find people that have more than one of these traits or "good enough" secondary traits while being very good at their primary traits.
From my personal experience, people who understand the pain points of the customer. And i mean serious ones, not just "it'd be nice to have". I've seen a lot of team members want to build elaborate features that do a hundred different things, but none of which actually solve a problem
In terms of hiring, someone who can own up to how they can improve, and have done extensive research into your company before hand and resonate with what you're trying to do. Those people seem to care a lot
