Supabase raises $150m and acquires Turso to power AI databases

Database developer Supabase has raised $150 million in a new funding round led by Singapore’s sovereign wealth fund GIC, alongside the acquisition of fellow database startup Turso.

The capital injection, which also featured participation from Google parent Alphabet’s CapitalG, IronArc, and SquarePeg, was announced alongside the purchase of Turso for an undisclosed sum. Supabase intends to use the money to provide liquidity for employees and to build out features specifically designed for artificial intelligence workloads.

The twin announcements point to a rapid shift in software development. The rise of autonomous AI agents has triggered a massive wave of database creation. Because these agents constantly build prototypes, dashboards, and temporary applications, they need to spin up and tear down databases at a scale traditional infrastructure was never designed to handle.

Why is Supabase acquiring Turso?

As AI agents build more software, database demand is expected to surge. Supabase, which is built on the popular open-source PostgreSQL relational database, claims it is already launching more than one million databases every week. PostgreSQL is highly prized for its reliability, and Supabase builds on this with paid features like user login management, automated backups, and task scheduling. It also supports vector embeddings, which allow neural networks to store knowledge.

However, spinning up a full PostgreSQL instance for every minor task or temporary agent is resource-heavy and expensive. That is where Turso's technology fits in.

"Agents should be able to create a database as easily as creating a file, with just as little concern about cost," Supabase co-founder and chief executive Paul Copplestone said in a statement. "For smaller workloads, that shouldn’t require provisioning a dedicated machine every time."

How does SQLite fit into the AI agent boom?

Turso offers a solution through its architecture built on SQLite—a highly efficient, open-source database engine that has a small hardware footprint and can run on low-power devices. Turso rebuilt SQLite in Rust to create a cloud platform capable of managing millions of databases on a single server, active only when needed and suspended when idle. It also supports embeddings and encrypts individual storage pages to reduce security risks.

Companies like Superhuman, Sauna.ai, CTO.new, and Mastra already use Turso to spin up on-demand databases for individual users or tasks.

The acquisition coincides with the launch of Supabase Compute, a new service that provides hosted sandboxes for long-running AI agents. These agents will be able to use Turso's lightweight SQLite instances for quick operations, keeping costs down without needing a full-scale relational database.

What is next for Supabase and Turso?

Despite the acquisition, Supabase says nothing will change immediately for existing users. Supabase will continue to focus on Postgres, while Turso will go on developing its SQLite platform.

Turso's co-founders, Glauber Costa and Pekka Enberg, will join Supabase along with their team. Costa is set to lead the startup's new agentic infrastructure division.
