Supabase has raised $100 million in a Series E round at a $5 billion valuation, with Accel and Peak XV leading the investment. The milestone comes just four months after the company closed its $200 million Series D at a $2 billion valuation, also led by Accel.
That Series D followed another raise just seven months earlier — an $80 million Series C backed by Peak XV (the Sequoia spinoff) and David Sacks’ Craft Ventures. PitchBook estimated Supabase’s valuation at about $765 million post-money, even though the company did not disclose it at that stage.
In total, Supabase has raised $380 million in the past year and now boasts more than $500 million in cumulative funding. The rapid funding cadence marks a valuation surge of over 500% within twelve months, assuming PitchBook’s Series C estimate is accurate.
Founded in 2020 by CEO Paul Copplestone and CTO Ant Wilson, Supabase emerged as an open-source Postgres-based alternative to Google’s Firebase, initially incubated at Y Combinator. While Firebase was designed to power AI applications, Supabase sought to offer developers a more open, flexible option.
The platform integrates Postgres with enterprise-grade open-source tools, enabling features such as authentication, auto-generated APIs, file storage, and a vector toolkit for AI apps. By reducing the complexity of database setup to a few clicks, Supabase quickly gained traction as a go-to backend for “vibe-coding” tools that generate apps from natural language prompts. Its adoption has expanded to fast-growing startups like Lovable and Bolt, as well as popular AI-focused tools like Replit, Cursor, Claude Code, and even Figma.
With a community of more than 4 million developers, Supabase remains committed to its open-source ethos. In line with that vision, the company announced that community members will also have the opportunity to purchase stock as part of the Series E round.
