Agent Database Platform Supabase Raises $150M, Acquires Turso

Just four months after closing a $500 million Series F, Supabase is raising again. It announced $150 million in new funding along with the acquisition of database startup Turso, all in one go.

Supabase is an open-source Postgres platform that bundles the databases, authentication, storage, and edge functions an app needs for its backend. It became a unicorn with a $200 million Series D in April 2025, followed by a $100 million Series E that October and a $500 million Series F at a $10.5 billion valuation in June. The new round was led by Singapore’s sovereign wealth fund GIC, with participation from CapitalG, Alphabet’s independent growth fund, as well as IronArc and SquarePeg. The company did not disclose a valuation for this round. Part of the funding will provide liquidity for employees’ shares.

AI agents are driving the growth. Supabase now adds more than 1 million users and 4 million databases every month, and 70% of new databases are created by agents or AI-driven tools — up from 60% when it announced the Series F in June. As AI coding tools like Claude Code and Codex write apps on developers’ behalf, the backend databases those apps need are increasingly spun up by agents rather than people. The platform now has more than 13 million developers.

Why Turso

If every app an agent builds needs its own database, the number of databases balloons far beyond what humans ever created by hand. Launching a dedicated server for each one would be too costly and too slow. Supabase’s view is that an agent should be able to create a database as easily as creating a file. Small, short-lived workloads suit lightweight SQLite, while Postgres is what you want as an application scales — and the developer experience should carry over from one stage to the next.

Turso built the architecture for exactly that pattern. It rewrote SQLite in Rust and built a cloud platform where a single server can manage millions of databases, loading each when needed and suspending it when idle. Services including Superhuman, Sauna.ai, CTO.new, and Mastra run per-agent databases on it. The Turso platform will keep operating, with a path into the broader Supabase ecosystem. Financial terms were not disclosed. Turso founder Glauber Costa will join Supabase as Head of Agentic Services alongside co-founder Pekka Enberg. Costa made his name as a Linux kernel contributor and has worked as an infrastructure engineer at Red Hat, ScyllaDB, and Datadog. Supabase’s official blog says nothing changes for existing users.

Supabase was founded in 2020 by Paul Copplestone and Ant Wilson. CEO Copplestone previously built a services marketplace in Southeast Asia and co-founded office-management startup Nimbus. He says agents are the future, and that Turso’s architecture will help Supabase become the backend platform for it.

The Competition

Consolidation is already underway in agent databases. Serverless Postgres company Neon was acquired by Databricks for roughly $1 billion in May 2025, in part because so many of its databases were being created by AI agents rather than humans. PlanetScale competes as an independent serverless database, while Google’s Firebase offers a large integrated backend service. With Turso now folded into Supabase, independent agent-database companies are visibly gathering under bigger platforms.
