Everything you need to find the right partner
Built specifically for founders, operators and investors.
Smart matching
Matched on complementary skills — not similar ones. A builder needs a seller, not another builder.
Mutual match only
Chat only unlocks when both people connect. No cold messages, no awkward intros.
Work style quiz
We match on how you work, not just what you do. Async vs sync, risk tolerance, decision pace.
Verified profiles
LinkedIn sync and portfolio links so you know exactly who you're talking to.
Starter prompts
Every chat opens with a question designed to spark a real conversation, not a cold hey.
Match analytics
See your compatibility breakdown — exactly why you scored high with each match.
