Supabase Raises $150M and Acquires Turso to Give Every AI Agent Its Own Database

The round was led by Singapore's sovereign wealth fund GIC, with participation from CapitalG, IronArc and SquarePeg. It lands just four months after Supabase closed a $500 million Series F in June that valued the company at $10.5 billion; the company did not disclose a valuation for the new round. Part of the new money will provide liquidity to employees.

Supabase says more than 13 million developers now use its platform, and it is adding over one million users and four million databases every month. Roughly 70 percent of those new databases are created by agents or AI-driven tools rather than people, up from 60 percent when the Series F was announced in June.

Co-founder and chief executive Paul Copplestone framed the bet plainly: as AI coding tools such as Claude Code and Codex let more people build software, the backends those apps need are increasingly created by machines. An agent that builds an app for every user needs a database as easily as it creates a file — and launching a dedicated server for each one would be far too costly and too slow.

Turso rebuilt SQLite in Rust and runs a cloud platform where a single server can manage millions of databases, loading them when needed and suspending them when idle. That makes it a natural home for short-lived, per-agent databases, while Supabase's Postgres remains the destination as an application becomes durable and traffic grows.

Supabase describes the intended path as a ladder: an agent starts with a tiny isolated database, then graduates into Postgres as the application matures. Turso's founder Glauber Costa, who will become Supabase's Head of Agentic Services, said the two companies share a commitment to developers, open infrastructure and agentic databases. Turso's existing platform will keep operating, with a migration path into the broader Supabase ecosystem.

Investors are pouring money into the plumbing underneath the agent boom. The Supabase deal follows a string of large AI infrastructure rounds, and CapitalG's Derek Zanutto characterized Supabase as a critical open infrastructure layer for the AI build-out.

With agents now creating the majority of new databases on its platform, Supabase is betting that the company that gives every agent its own database cheaply and instantly will become the default backend for the next wave of software. Whether Turso's architecture can handle that scale inside Supabase's ecosystem is now the question the next few quarters will answer.
