Supabase Raises $150M Led by GIC, Acquires Turso for AI Agent Databases

Supabase has raised $150 million in new growth funding led by Singapore's GIC and is acquiring database startup Turso, a pairing that signals where the San Francisco company sees its next phase of growth: databases built for AI agents rather than only for the developers who write code by hand.

The company announced the financing and the acquisition together. Alphabet's CapitalG, IronArc and SquarePeg also participated in the round, which arrives just four months after Supabase closed a $500 million Series F.

What Supabase Does

Supabase is an open-source development platform built on Postgres. It gives developers a managed backend in one place, including a Postgres database, authentication, file storage, edge functions, real-time subscriptions and vector search. The company now describes itself as agentic infrastructure, reflecting how much of its usage comes from AI coding tools that spin up backends on a user's behalf.

Growth Numbers Behind the $150M Round

The scale of that shift shows up in the company's own figures. Supabase says 13 million developers use the platform, and that it is adding more than 1 million users and 4 million databases every month. Roughly 70% of new databases are now created by agents or AI tools rather than by a person clicking through a dashboard. As of June, the number of databases on the platform had grown 600% year over year.

Those numbers help explain why investors returned so quickly after the Series F. Every AI-generated app still needs somewhere to store data, and Supabase has become a default choice for many of the tools generating them.

Why Supabase Is Acquiring Turso

Turso is a database platform designed for agentic workloads, the high-volume, short-lived database activity that AI agents produce. Founder Glauber Costa will join Supabase as Head of Agentic Services, alongside Turso co-founder Pekka Enberg. Supabase says the Turso platform will keep operating, with a pathway for customers into the Supabase ecosystem.

"The future is agents and the architecture Turso provides will help us accelerate Supabase," said Paul Copplestone, co-founder and CEO of Supabase, in the announcement.

Financial terms of the acquisition were not disclosed.

How Supabase Will Use the Funding

The company plans to put the capital toward product development around agent-driven databases. A portion of the round is also earmarked for employee liquidity, giving staff a way to sell some of their shares while the company remains private.

What It Means for Developers

For teams building on Supabase, the practical read is continuity with more investment behind it. The core Postgres platform stays in place, while the Turso deal adds architecture aimed at workloads where thousands of small databases are created and discarded by software.

For the wider market, the round is another data point in the race to own the infrastructure layer under AI-built applications. Backend providers are competing to become the automatic choice when an agent needs a database, and with $650 million raised in four months and a sovereign wealth fund now leading its cap table, Supabase has the resources to press that advantage.
