Open source database startup Supabase has announced a $100 million Series E funding round, valuing the company at $5 billion. The round, led by Accel and Peak XV, comes just four months after the company’s $200 million Series D at a $2 billion valuation, and seven months after an $80 million Series C. Altogether, Supabase has raised $380 million in the past year and $500 million since its launch.
Founded in 2020 by CEO Paul Copplestone and CTO Ant Wilson, Supabase began as a Y Combinator project offering a Postgres-based open source alternative to Google’s Firebase. Its platform integrates authentication, auto-generated APIs, file storage, and a vector toolkit to simplify database setup for developers, reducing complex processes to a few clicks. This approach has made it a favorite backend option for the fast-growing “vibe-coding” ecosystem.
Supabase has become increasingly popular among AI coding tools such as Lovable, Bolt, Replit, Cursor, and Claude Code. The company also counts major platforms like Figma as users. Its rapid growth has been fueled by the surge in AI-driven app development, where developers rely on easy-to-use, scalable infrastructure to handle high demand.
In a unique move, Supabase said community developers, who now number around four million, will be able to participate in the latest funding round by purchasing stock. The company says this decision underscores its open source ethos and commitment to giving its developer community a stake in its future as it continues its aggressive growth trajectory
