I signed up like 1 week ago and I'm a 2nd time founder. It depends on your expectations and how you configure it is my read. For me, even though I'm technical, I'm mostly looking for other technical founders. Other than that, the thing I mainly want to feel when I read a profile is a sense of "oh this person would be fun to jam on ideas with" and in addition, "yea I think they got the same level of hustle/urgency as I do." Concurrently, I want to get a sense of the person's motivations - are they all about the $$, I'm a pass usually in that scenario. I just want to build something people love.
I think I've already seen a few people who match that criteria.
Aside: kinda worried about how many people are looking to start an "ai startup" rather than solve a problem which might involve AI.
