Overview

Pax Historia is a San Francisco-based AI-powered alternate-history grand strategy sandbox game platform. Players create, edit, and publish maps and presets, then play out counterfactual scenarios with AI-driven nations and events. Public sources conflict on the founding year (2024 vs. 2025), so I use 2024 from the LinkedIn company/lead-profile evidence.
