Zero to One
Zero to One is a startup founder simulation game where you go from getting laid off at Meta to pitching at YC Demo Day.
Core trick
Each NPC keeps a persistent memory store shared across characters, and a deterministic engine gates progression around LLM-generated dialogue.
Description
Zero to One is a startup founder simulation game where you go from getting laid off at Meta to pitching at YC Demo Day. Every NPC (Garry Tan, early users, VCs) is powered by Gemini with persistent cross-NPC memory — what you tell one character affects how others treat you. The game uses Gemini 3 Flash for dynamic scene generation (NPC dialogue + player choices), Gemini 2.5 Flash TTS for real-time character voice acting with lip sync, and a deterministic game engine layered on top so LLM creativity doesn't break progression. Built with Next.js, TypeScript, Zustand, and Tailwind.
