Most founder communities sell access. Mezzanine offers expertise. Network matching founders into circles of 6-8 peers in their city — meeting monthly, in person, no screens. Vetted by ambition, not revenue. Mentored by operators, not influencers. 1:1 sessions with founders who've actually scaled and exited. Plus Ping Pong, Padel, dinners, retreats, and running clubs across 24 cities. Entrepreneurship is lonely. We give you a room of people who are in it with you.
