Supabase $150M Round: GIC Leads, Turso Buy Targets AI Agents

What happened

Supabase, the open-source backend platform built on Postgres, has raised $150 million and announced it is acquiring database startup Turso in the same move 13. Singapore's sovereign wealth fund GIC led the round. Alphabet's independent growth fund CapitalG also participated, alongside IronArc and SquarePeg 3.

The company says both the money and the acquisition are meant to speed up work on databases built for AI agents 1. Part of the round will also go toward liquidity for employees 13.

The timing is notable. The round comes roughly four months after Supabase closed a $500 million Series F at a $10.5 billion valuation in June, a round GIC also led 13. That deal followed a $100 million Series E in October 2025 at a $5 billion valuation and a $200 million Series D in April 2025 that first made the company a unicorn 13.

Conflicting details on terms

Reports differ on several particulars:

• Valuation. Supabase did not disclose a valuation for this round 3. Layerbase, citing Y Combinator, reports a figure of $10.65 billion, only slightly above June's mark 5.
• Total raised. One account puts Supabase's cumulative funding past $1 billion 1. Layerbase counts four raises in 18 months totaling about $950 million 5. That figure matches the sum of the Series D, E, F and this round.
• Who led and how it is labeled. Stackademic describes GIC and CapitalG as co-leads and calls the deal a "Series E extension" 2. That label sits awkwardly next to a completed Series F, and other outlets describe GIC as sole lead with CapitalG participating 34.

The most defensible reading is a GIC-led growth round with CapitalG adding weight. A modest step-up, if the $10.65 billion figure holds, would suggest the round is less about repricing the company than about funding consolidation and rewarding staff.

Why agents are the story

The core argument is usage. Supabase says it now adds more than 1 million users and 4 million databases every month, and that 70% of new databases on the platform are created by AI agents rather than by people clicking through a dashboard 3. The company links this surge to coding tools such as Claude Code and Codex, which are widening the pool of people who build software and multiplying the number of apps they ship 1.

Stackademic frames the deal as Supabase trying to become the default backend for agentic coding tools: systems that scaffold apps, migrate schemas and provision infrastructure on their own 2.

Turso fits that goal. It makes lightweight, embedded, SQLite-compatible databases that can be spun up on demand for edge and serverless workloads 2. That suits agents that create and discard databases constantly 1. Turso's founders, Glauber Costa and Pekka Enberg, are joining Supabase 4.

The Venture Capital Archive newsletter pointed out that because the raise and the acquisition landed together, part of this funding round is effectively paying for consolidation 4.

The consolidation pattern

The deal also fits a broader trend. Layerbase notes that Databricks bought Neon for roughly $1 billion and Snowflake acquired Crunchy Data for about $250 million in 2025 5. With Turso, three of the best-known independent Postgres and SQLite infrastructure startups have been absorbed by larger platforms in under a year 5.

The likely logic is that agent-driven app creation rewards whoever controls the default database layer, and buying that layer is faster than building it.

The open-source question

One point deserves more attention than it has received. Turso's libSQL engine, a fork of SQLite, was reportedly already in maintenance mode before the deal 5. Costa is moving into an agentic-services role at Supabase rather than continuing to steward libSQL directly 5.

That leaves the fork's future with a company whose stated roadmap is to move SQLite users onto Postgres 5. Developers who built on libSQL may want clarity on support before assuming it will continue to evolve.

Our read

Supabase is using its position as a favored backend for AI-generated apps to raise capital quickly from deep-pocketed, repeat backers and turn some of it into acquisitions. The 70% agent-created figure is the number to watch. If it holds, the database market's center of gravity is shifting from human developers to the tools acting on their behalf. Smaller infrastructure players will face pressure to sell to the platforms those agents pick by default.
