Supabase Raises $150 Million and Buys Turso for A.I. Agents

Supabase is leaning harder into the idea that A.I. agents need databases the way builders need tools. The company has raised $150 million, or about 128 million euros, and it is also buying Turso, a database specialist focused on lighter-weight workloads for agents. SiliconANGLE reported the deal. The round is led by Singapore’s sovereign wealth fund GIC, with CapitalG, IronArc and SquarePeg also in the mix.

This comes only months after Supabase’s last big fundraise. In June, it raised $500 million in a Series F at a $10 billion pre-money valuation, again led by GIC. Supabase has not said what this new round values the company at. Some of the cash is set aside for employees who want to sell shares. The rest is going toward new features for A.I. agents, which is where the company thinks the demand is.

And the demand is not subtle. Supabase says more than 13 million developers now build on its platform, up from just under 10 million in June. More than one million users and four million databases are added every month. Around 70 percent of new databases are created by A.I. agents or A.I. tools, and the number of databases launched is up 600 percent year over year.

Supabase was founded in 2020 by Paul Copplestone and Ant Wilson, and it sits on PostgreSQL, adding things like user management, automated backups and scheduled tasks. Turso brings a different piece of the puzzle: a lightweight SQLite-based database aimed at A.I. agents, with support for embeddings and page-by-page encryption. Its basic version is free, while the company sells a paid cloud offering. Supabase did not disclose the purchase price.

The pitch is straightforward enough. Agents are creating huge numbers of prototypes, dashboards and apps, and each one needs a database that can be spun up quickly and cheaply. Turso is meant to help power Supabase Compute, the company’s hosted environment for long-running A.I. agents. Turso founder Glauber Costa is joining Supabase with his team and will lead agentic services. Meanwhile, the competition keeps piling in: Databricks bought Neon last year, and PlanetScale and Google’s Firebase are still chasing developers too.
