Supabase raises $150m and buys Turso to fuel AI coding surge

Supabase, the Singapore-based database platform, has raised an additional $150 million in funding and acquired database-on-demand startup Turso. The rapid double-move comes just four months after the company announced a massive $500 million Series F round, as it scrambles to support an extraordinary surge in AI-generated software development.

The new funding round was led by Singapore's sovereign wealth fund, GIC, and brings in Google’s growth fund, CapitalG, as a first-time investor. That backing is notable because one of Supabase’s primary competitors is Firebase, which is owned by Google. Supabase chief executive Paul Copplestone said the investment fund’s connections to the broader Alphabet ecosystem would be highly valuable as the startup prepares for its next phase of growth.

The fresh capital brings Supabase’s total funding to more than $1 billion. Its existing roster of high-profile backers includes Accel, Peak XV, Craft, Coatue, Y Combinator, Stripe, Salesforce Ventures, and Figma.

What is driving the growth

A smaller funding round coming so hot on the heels of a half-billion-dollar raise is unusual, but Supabase is scaling at a pace that demands rapid infrastructure expansion. According to figures released by the company, the platform is now adding more than one million users and four million databases every single month.

The real story behind those numbers is the rise of AI. Fully 70% of those four million new databases are now being created by automated agents and AI-driven tools, rather than human engineers writing code by hand. This follows a massive 600% year-on-year increase in databases reported in June, when AI bots were already responsible for the majority of new deployments.

In this environment, where tools like Claude, ChatGPT, and dedicated coding bots can write and launch functional apps in minutes, the bottleneck has shifted from writing code to provisioning backend infrastructure.

Why Supabase bought Turso

To solve that bottleneck, Supabase has acquired Turso, a startup that allows databases to be spun up instantly on demand.

When AI agents are building software on the fly, the underlying databases need to be created and configured just as quickly. Turso’s technology will allow Supabase to manage the sheer volume of databases being demanded by these automated workflows. The company wants its tools to be the default backend for any software created by AI bots.

Although its founders are not Singaporean, they met in the country during an Entrepreneur First accelerator cohort. The company has since grown into a multi-billion-dollar global business from its Singapore base, proving that startups in the city-state can scale internationally without being confined to regional markets.
