Supabase Inc. has raised $150 million in a funding round led by GIC, Singapore’s sovereign wealth fund. Alphabet Inc.’s CapitalG, IronArc and SquarePeg also participated in the deal. The startup, which commercializes the open-source PostgreSQL database, announced the raise today alongside an agreement to acquire fellow database startup Turso for an undisclosed sum.
Supabase sells a paid version of PostgreSQL, one of the most widely used relational databases because it is free and reliable. Its paid offering adds capabilities including easier management of user logins and backup generation. An implementation of the open-source Cron tool lets customers schedule automated data management tasks at intervals they define. The company also offers features tuned for artificial intelligence workloads, such as storage for embeddings, the data structures neural network models use to retain knowledge. An MCP server allows external AI agents to read and edit records.
The Turso acquisition is intended to extend those AI capabilities. Turso offers a database optimized for AI agents and based on SQLite, an open-source relational store with a small hardware footprint that can run on low-power devices including smartphones and wearables. AI agents frequently create databases to hold the information they collect or generate, and a coding assistant, for example, may need to retain programming instructions supplied by the user. Turso’s hardware efficiency allows agents to spin up databases almost instantaneously, cutting wait times for users.
Turso adds features not available in SQLite out of the box. It supports embeddings and encrypts each database page, or unit of storage, in a slightly different way, which reduces hacking risk. Its core feature set is free, and it monetizes through a paid cloud version that automates infrastructure management.
Supabase could apply Turso’s technology to Supabase Compute, a new cloud service it introduced today that provides hosted sandboxes for long-running AI agents. Those agents may benefit from spinning up lightweight Turso instances for simple tasks that do not need a full relational database. Supabase co-founder and Chief Executive Paul Copplestone wrote in a blog post that agents are spinning up millions of databases to power prototypes, explorations, dashboards and apps, and that this pattern at massive scale requires an evolution in database infrastructure.
Supabase will use the funding proceeds to provide liquidity for employees and to build new AI agent features. The round and the acquisition target the growing US market for AI infrastructure, where agent-driven workloads are pushing demand for lightweight databases that can be created quickly and managed automatically.
