Supabase will win a $5 billion valuation four months after reaching $20 billion

A selection database of atmosphere worlds: For Supabase, it was a whirlwind year. On Friday, Supabase announced it had raised a fresh $100 million Series E at a $5 billion valuation led by Accel and Peak XV. This is just four months after closing the $200 million Series D at a $2 billion valuation led by Accel.

And that Series D came just seven months after raising an unreleased rating of the $80 million Series C, led by Sequoia Spinoff Peak XV and David Sacks’ Craft Ventures. Pitchbook estimated that Supabase was valued at approximately $765 million in its agreement, post money.

So, assuming Pitchbook’s estimate of Series C ratings is in the ballpark, $380 million will be raised over a year, increasing the valuation stage of over 500%. Supabase is currently raising a total of $500 million.

Open source database service Supabase was founded in 2020 by CEOs Paul Copplestone and CTO Ant Wilson (pictured above) a few years before the LLM-powered Vibe-Coding epidemic. Originally, it was the Y Combinator startup that provided developers with post-gress-based open source, which replaces Google’s Firebase. FireBase is a database designed to power AI apps.

Supabase combines other enterprise-grade open source tools targeting features such as authentication, auto-generated APIs, file storage, and vector toolkits (required by many AI apps). A few clicks on the database simplified the difficult part of setting up a database. The result has become the popular backend for vibe coding tools that write apps at natural language prompts, like the rapidly growing adorable bolt. It is increasingly used as the best database for Figma and other popular AI coding tools.

Interestingly, the company says that Supabase is open source and supported by a community of developers who claim to be 4 million developers as users, allowing community members to purchase stocks as part of the Series E funding.
