Jack Arenas invests or supports investments through Founder Collective's published strategy: Back weird and wonderful, sector-agnostic seed companies where founders have strong founder-market fit and can create intrinsic customer value efficiently.

Hype without intrinsic customer value, poor founder-market fit and capital-inefficient strategies conflict with the firm's published ethos.
