Supabase raises $150M, agrees to acquire Turso

Supabase secures $150 million

Supabase Inc., a startup that commercializes the open-source PostgreSQL database, has raised $150 million in funding. Singapore's GIC sovereign wealth fund led the round, joined by Alphabet Inc.'s CapitalG, IronArc and SquarePeg. Supabase announced the financing on October 2, 2026, alongside an agreement to acquire fellow database startup Turso for an undisclosed sum.

Supabase offers a paid version of PostgreSQL with additional capabilities, including user login management, backups and scheduled data management tasks through an implementation of the open-source Cron tool. It also provides features for artificial intelligence workloads, including storage for embeddings, which are data structures where neural network models retain knowledge.

Turso targets AI agent workloads

Turso offers a database optimized for AI agents and based on SQLite, an open-source relational database with a small hardware footprint. SQLite can run on low-power devices such as smartphones and wearables. AI agents often create databases to store information they collect or generate. A coding assistant, for example, may need to retain programming instructions supplied by a user.

Turso's lightweight design allows agents to start database instances nearly instantaneously, reducing wait times. It also provides features not available in SQLite out of the box, including support for embeddings and a method of encrypting each database page that reduces the risk of hacking. Its core features are available for free, while a paid cloud version automates infrastructure management.

Supabase expands its agent infrastructure

Supabase could use Turso's technology to enhance Supabase Compute, a new cloud service providing hosted sandboxes for long-running AI agents. Those agents could create lightweight Turso instances for simple tasks that do not require a full relational database.

Supabase co-founder and CEO Paul Copplestone said AI agents are spinning up millions of databases for prototypes, explorations, dashboards and applications. He said the pattern requires an evolution in database infrastructure. Supabase will use the funding proceeds to provide liquidity for employees and build new features for AI agents.
