LottieFiles and the business of a tiny moving heart
A little animation can create a surprisingly large amount of work. LottieFiles built a business around making that work disappear - from the first keyframe to the app in your hand.
Figma
Figma won by turning interface design into a shared room. Now the public company is trying to make that room the place where ideas, code, AI and the people with opinions about all three finally meet.
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.
