HOW IT WORKS
Both sides set filters. Both sides swipe. A match only happens when interest goes both ways — so every conversation starts warm.
Your pitch, traction, and what you're looking for. Founders show numbers, investors show thesis and check size, cofounder seekers show skills and availability.
Stage, sector, geography, check size. Your deck only shows profiles that clear your bar — and whose bar you clear.
Mutual interest opens the chat. Share the deck, book the call, skip the cold-email dance.
TRY THE MECHANIC
Pass with ×, connect with the heart. When the interest is mutual, a chat opens — that's the whole product. Try it on three real-format cards, no account needed.
