The Supernova founder learned that generating code was the easy demo. The durable company would have to understand everything around it.
Supernova
Supernova is an AI-powered platform that turns a company's design system into structured context that both people and AI coding agents can use. Founded in Prague and now building a U.S. headquarters in San Francisco, it centralizes design tokens, component APIs, documentation and rules as a single source of truth, then feeds that context into tools like Figma, Storybook, Cursor, GitHub Copilot and Claude Code so product teams can prototype, hand off and ship features faster. A Y Combinator alum, it is used by hundreds of organizations including Air France, KLM, Kraft Heinz, Paramount, Mozilla, LaunchDarkly and Skyscanner.
