Supabase raises $150M and buys Turso to become the database layer for AI agents
Supabase announced $150 million in new funding led by GIC and the acquisition of Turso, betting that agents creating millions of databases need infrastructure built for on-demand, per-agent databases.
Supabase wants to be the database that AI agents reach for, and it just bought the company built for exactly that workload. The open source Postgres platform announced on October 2 that it has raised $150 million in new funding led by GIC, with CapitalG, IronArc, and SquarePeg participating, and that it is acquiring Turso, the company behind a high-volume SQLite platform for agentic workloads. The round comes just four months after Supabase's $500 million Series F.
The numbers explain the urgency. Supabase says it is now adding more than 1 million users and 4 million databases per month, with 70% of new databases created by agents or AI-driven tools, and that it is launching over one million databases per week. Those are company-reported figures; the announcement does not define how it counts users or databases. The growth follows a 600% year-over-year increase in databases that the company reported in June, when agents were already deploying the majority of new databases on the platform.
Why Turso fits the agent pattern
Turso is the infrastructure answer to that curve. The company rebuilt SQLite in Rust and built a cloud platform where a single server can manage millions of databases, loading them when needed and suspending them when they are idle. That makes it possible to provision a database per agent on demand, whether on Turso Cloud or in customers' own clouds, an architecture already used by customers including Superhuman, Sauna.ai, CTO.new, and Mastra. Turso will keep operating its existing platform, with Supabase planning a path for customers into the broader Supabase ecosystem as workloads grow.
For existing users, the companies say nothing changes: Supabase continues building around Postgres, Turso continues its work on SQLite, and Turso co-founders Glauber Costa and Pekka Enberg join Supabase with the rest of the team, with Costa leading the agentic infrastructure effort. Paul Copplestone, Supabase's co-founder and CEO, framed it as a future bet: "The future is agents and the architecture Turso provides will help us accelerate Supabase as the backend platform for supporting that future." The round will also provide employee liquidity.
The thesis behind the deal is simple enough to state: agents should be able to create a database as easily as creating a file, without provisioning a dedicated machine each time. SQLite fits small, on-demand workloads; Postgres fits applications that scale. Supabase is now trying to own both ends of that path, from the first agent-spun prototype to production.
