Supabase, the open source database of choice for the vibe-coding world, has raised a $500 million Series F at a $10 billion pre-money valuation, the company announced Friday. That’s about $10.5 billion after the investment.

The newly minted decacorn has been doubling its valuation every few months for a couple of years now, as vibe-coding tools have driven its usage to astounding growth: over 600% in the past year, with over 60% of new databases launched “by some sort of AI tool,” CEO and co-founder Paul Copplestone wrote in a blog post announcing the raise.

The startup also now claims nearly 10 million developers as users, which has doubled in eight months. Copplestone particularly credits Claude Code and Codex for this growth because the popular AI models “expand the number of people who can build.” Supabase is also a database of choice for Bolt, Figma, Lovable, Replit, and others.

This new influx of cash follows a $100 million round at a $5 billion valuation in October. And that raise came just months after closing $200 million at $2 billion.

Supabase uses popular open source database Postgres as its engine, a database launched long before AI was a twinkle in Sam Altman’s eye. One of the more interesting things about Supabase is the work it’s doing to make Postgres less of a maintenance hog for developers and vibe coders as their apps grow and attract users.

For instance, it also this week launched a tool called Multigres that it describes as an “operating system” for Postgres. It’s intended to ease the complexity of running Postgres at scale, giving developers a central way to manage pesky tasks like read replicas, failovers, connection limits, backups, and so on.

Another interesting thing about the company involves the choices Copplestone made to build it. He told us on an episode of the Equity podcast in November how he refused to partake in the “sh*tification” of developer tools because he wouldn’t cater to enterprises offering multimillion-dollar contracts that then make product demands. Instead, he sticks to his own product vision. That’s the reverse strategy of most startups, but there’s no denying it’s been working for Supabase.

The round was led by GIC, with existing investors piling in like Stripe, and new investors Georgian and Salesforce Ventures.
