Pax Historia

Pax Historia is an alternate-history sandbox game where players choose a country, a moment in time, and rewrite the course of history. What if Rome never fell? What if the Soviet Union survived? What if Genghis Khan ruled for another generation?

We’re backed by Y Combinator, Pace Capital, and Z Fellows, have seen nearly 20 million rounds played, and are growing quickly. Your work will immediately ship to a product used by hundreds of thousands of players.

We're pushing the limits of what's possible with current AI models and web-based mapping libraries. Beyond a pretty standard stack (NextJS, Firestore, Supabase, and R2) we're developing custom tile serving infra, evals, harnesses, embedding models, generative models, and more.
