GTO World is a curated startup ecosystem for founders, operators, and investors, bringing together more than 10,000 members across cities including London, New York, San Francisco, Munich, Berlin, Lisbon, Barcelona, Zurich, Shanghai, and Austin. Its guiding principle is mutual benefit: when one member succeeds, the wider network should benefit too. GTO views startups and startup communities through the lens of game theory, arguing that founders and other participants make decisions with distinct actions and goals, and that the ecosystem has substantial unrealized potential.

The community offers ways to connect, collaborate, and participate through events, a fellowship, ventures, media, and jobs. Members can meet peers, invest in the network, hire from it, or help build the ecosystem. GTO also presents its ideas through a startup-focused thesis and positions its network as a source of advantages for people who reason mathematically about building companies. Its offering is designed to help members play, invest, hire, and build within a connected community where individual and collective success are linked.
