I tried the YC founder matching thing several years ago. It was terrible. It asked all sorts of irrelevant questions and then used the answers to disqualify me from the service.

They overthought the problem. All thats needed is a list of people who are looking to connect plus their resume and a summary paragraph. Like a dating website basically. To keep it fresh and focused it should require you click a”still looking” email link once a week. Maybe fields for location/are you technical.

It might have changed in recent years but I never went back.
