## About Worldbuild

Worldbuild is a thesis-driven venture capital firm based in New York that partners with creative technologists at pre-seed and seed. Its debut fund, Worldbuild I, closed at $30 million in May 2026, with a top 20 university endowment and multi-stage VC firms among its LPs.

It backs founders in two categories: Model Economy Infrastructure, spanning the compute, data, energy, and security that AI models need to improve, and Post-Skeuomorphic Applications, workflows that become possible only because of AI.

Worldbuild is led by a solo general partner and former a16z partner who turns published theses on tech trends into early investments, backing technical founders before products reach market.
