Supabase, the preferred database in the vibe-coding community, has experienced a remarkable year. On Friday, the company revealed it secured a new $100 million Series E round at a $5 billion valuation, with Accel and Peak XV leading the investment. This comes only four months after it wrapped up a $200 million Series D, also led by Accel, at a $2 billion valuation.
That Series D followed just seven months after Supabase closed an $80 million Series C, which was led by Peak XV, a Sequoia offshoot, and Craft Ventures, founded by David Sacks. The valuation for that round wasn’t disclosed, but PitchBook estimated Supabase’s post-money value at about $765 million.
Altogether, Supabase has brought in $380 million in funding over the past year, with its valuation jumping more than 500%, assuming PitchBook’s Series C estimate is accurate. The company now reports a total of $500 million raised to date.
Supabase, an open source database platform, was established in 2020 by CEO Paul Copplestone and CTO Ant Wilson (pictured above), predating the surge in LLM-driven vibe-coding. The company began as a Y Combinator participant, aiming to provide developers with an open source, Postgres-based alternative to Google’s Firebase—a database also built to support AI applications.
Supabase integrates Postgres with a suite of enterprise-level open source tools, offering features such as authentication, automatically generated APIs, file storage, and a vector toolkit essential for many AI projects. By streamlining the complex process of database setup to just a few clicks, it quickly became a favored backend for vibe-coding platforms—where apps are created using natural language prompts—like the rapidly expanding Lovable and Bolt. According to the company, it is also increasingly chosen as the database for Figma and other leading AI coding tools, including Replit, Cursor, and Claude Code.
Notably, Supabase’s open source nature and its developer community—which the company says numbers 4 million users—mean that community members are being given the opportunity to purchase shares as part of this Series E round, according to the company.
