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.
