Hello - I'm one of the people at YC who work on YC's co-founder matching site (which, if you aren't familiar with it, is at https://www.ycombinator.com/cofounder-matching ). It's not totally clear to me if OP is referring to that product specifically or something else, but I figured I would take the opportunity to get feedback anyway! We are very actively working on the co-founder matching site and would love to hear…
I’ve met more than a few pre seed folks who are focused on equity retention. This is all well and good for a few exceptional founders, and they are welcome to seek out a compatible match. However there should be an asterisk on when people are looking for a founding engineer or otherwise giving out marginal equity.
I had a few such meetings which were educational- but ultimately non productive as it would not make financial sense for me to join a seed stage firm for less than a 50% stake. Of course the discussion is different for later stage firms.
That being said the speed dating events were fantastic.
