+1 on the site being lower value than it could be for repeat founders with previous successes, but who still want to build things with other people with extensive experience and a track record.

You could argue that if you're in that situation you should be relying on existing networks to propel you into your next thing, but sometimes you want a new start or things just aren't aligning time-wise with your former allies.

The majority of folks on the site have never done a startup before and are entirely unproven in a startup context, or have a couple of short stints that they unfortunately didn't learn much from because the thing never gained any traction, so they did "1 year experience 3 times over". Doesn't mean they're not potentially great startup material, it's pretty hard to get something to take off. But, it's still a pretty risky bet for someone who wants to derisk partners a tad more.
