❯ Supabase raises another $150 million and acquires Turso to prepare for AI agents creating databases in bulk

A back-end toolkit for developersSupabase offers a development platform centered on the Postgres database, with authentication, file storage, real-time subscriptions and vector search, so developers can build apps without assembling their own back end. According to Runtime Wire, the platform has 13 million developers and adds 4 million databases a month, 70% of them created by AI agents or AI tools.

It raised $500 million in JuneIn June, Supabase closed a $500 million Series F at a $10 billion pre-money valuation, led by Singapore’s GIC. According to Trending Topics, it had about 10 million developers at the time, and its database count was growing 600% year on year.

Part of the new money cashes out staffThe $150 million announced this week is also led by GIC, with CapitalG, the growth fund of Google’s parent, IronArc and SquarePeg participating. The valuation for this round was not disclosed. Part of it lets employees sell shares they hold, and the rest goes to new features for AI agents. The company also introduced Supabase Compute, hosted sandboxes for long-running agents.

One database per agentSupabase also announced it is acquiring Turso for an undisclosed price. The deal is agreed but not closed. Turso is an open-source, SQLite-compatible database written in Rust that treats a database as a lightweight file instead of a standing server process and can be created on demand. Most of the 4 million databases Supabase adds each month are made by agents, and it needs a form of database that can be created instantly and in large numbers, which is the gap Turso fills.

▪ SIGNALThe main “user” of a database is shifting from developers to agents, so products will compete less on features and more on how cheaply and quickly an instance can be created.
