What does Tesana do?
Tesana is an AI game-creation platform that turns natural-language prompts into playable 3D games, using a proprietary engine (its closed-source Muranyi-3 model) that translates descriptions of environments, mechanics, characters and rules into structured game code. It ships a games marketplace, a desktop (Tauri) build and subscription tiers, and reported roughly 10,000 paying customers within its first weeks after demoing at GDC 2026. Co-founded by Johannes Vermandois (CEO) and Eric Heimer (CTO).
