Cosign

What it is

A reputation and vouching tool for the startup ecosystem — founders, investors and operators vouch for people they have actually worked with, so warm intros carry more weight.

Why I recommend it

Pricing is not published on the site, so treat the free tier as unconfirmed until you sign up. A vouching network is only as good as who else is on it.
