Supabase Raises $150 Million and Buys Turso Four Months After a $10 Billion Round

Supabase announced Oct. 2 that it raised $150 million in a round led by Singapore's GIC and agreed to acquire Turso, a SQLite database company, for an undisclosed price. Pulse 2, which republished the company's release, lists CapitalG, IronArc and SquarePeg as participants. The release does not give a valuation.

The round arrives four months after Supabase's Series F, posted June 4, which raised $500 million at a $10 billion pre-money valuation, also led by GIC. Part of the new money is employee liquidity, meaning staff selling shares rather than the company receiving cash, per RuntimeWire.

What the two rounds disclose

	Series F (June 4)	This round (Oct. 2)
Amount	$500 million	$150 million
Valuation	$10 billion pre-money	Not disclosed
Lead	GIC	GIC

The Series F post says employees can sell up to 25 percent of their vested stock in each funding round and have 10 years to exercise options after leaving. Under that policy, every round carries some liquidity, so a second one four months later is consistent with it. How much of the $150 million went to employees rather than the balance sheet is not given.

Why Turso, and what stays the same

In the acquisition post, Chief Executive Paul Copplestone writes that agents are creating millions of databases for prototypes and apps, and that Supabase already launches over one million databases per week. Turso rebuilt SQLite in Rust and runs a cloud platform where one server manages millions of databases, loading each when needed and suspending it when idle. Its named customers are Superhuman, Sauna.ai, CTO.new and Mastra.

The post says existing users see no change: Supabase keeps building around Postgres, and Turso keeps working on SQLite. The plan the post lays out is SQLite for small workloads and Postgres as an application grows, and the post puts it this way: "Postgres is what you want as your application scales." Turso founder Glauber Costa becomes Supabase's head of agentic services, and co-founder Pekka Enberg joins with the Turso team.

The usage numbers do not line up exactly

The blog says more than one million databases a week. The release says Supabase adds more than 1 million users and 4 million databases a month, which is roughly the same rate.

The share created by machines is where wording shifts. In June the Series F post said over 60 percent of new databases were launched through some A.I. tool. The October release says about 70 percent are created by agents or A.I.-driven tools. Those are different definitions, so the 10-point rise cannot be read as one trend. The release also gives more than 13 million developers on the platform, against nearly 10 million in the June post.

Copplestone said in the release: "The past year has been the fastest growth in our history by a wide margin." CapitalG General Partner Derek Zanutto called Supabase "the critical open infrastructure layer powering the AI revolution." Neither quote comes with a revenue figure, and the Series F post does not mention revenue either.

Elsewhere, Microsoft made its MXC sandbox for agent-written code generally available on Oct. 7, and Hone raised a $60 million seed for its A.I. agents. The next thing to watch is whether the Turso close is announced with a price, or only folded into a later round.
