- Joining and browsing are free

- Only matching searches appear, with the reasons
How it works
Say what you offer and seek
A short, structured profile: role, skills, how much time you commit, and your founder experience. Founders add a co-founder search for their venture.
See who fits, and why
Suggestions are ranked by a fit score that works in both directions. Every criterion shows what one side offers and what the other seeks.
Meet when both say yes
Send an intro with a personal note. Contact details are shared only after the other side accepts.
The fit score
See why it fits, before anyone talks
Once you have a profile, every suggestion is scored in both directions: what the search needs from a co-founder, and what the co-founder needs from the venture.
- Must-haves have to fit fully
- Each criterion shows the level of fit
- Rule-based and explained, no black box

Questions
What does it cost?
Cofoundista is free during the beta. Joining as a co-founder and browsing searches are free. Founders publish their co-founder searches for free during the beta.
Who can see my profile?
Visitors see search teasers, never your profile. Members with a checked profile see your first name, photo, role, skills, city and bio. Your full name, links and company names follow when you send someone an intro or accept theirs. Email and phone are shared only after both of you said yes.
How is the fit score calculated?
By rules, not by AI. Each criterion fits, partly fits or does not fit, and counts by its weight. Must-haves have to fit fully. Each side gets its own score, and the mutual score is the lower of the two, so a match has to work for both.
I have no idea yet. Can I still join?
Yes. Join as co-founder: you see searches from founders whose terms fit yours and can ask for an intro. Matching two people who both have no idea yet is not possible for now.
Where is Cofoundista available?
Cofoundista is for founders and co-founders in Europe: the EU, Iceland, Liechtenstein, Norway, Switzerland and the United Kingdom, starting in English and German. The beta phase starts with programme partners in selected countries.
