Supabase Raises $150M as AI Agents Drive Explosive Database Growth

Supabase, the open source Postgres development platform and agentic infrastructure company, has announced $150 million in new funding led by GIC. CapitalG, Alphabet's independent growth fund, along with IronArc and SquarePeg, also participated in the round.

The new investment comes only four months after Supabase's $500 million Series F and reflects the accelerating demand for backend infrastructure as AI coding tools and autonomous agents dramatically increase the amount of software being built.

Alongside the funding announcement, Supabase revealed that it is acquiring Turso, a database platform designed to help developers provide databases at significantly higher volumes for agentic workloads.

The combination of fresh capital and the Turso acquisition is intended to accelerate Supabase's development of infrastructure built specifically for the growing number of AI agents creating and operating software.

AI Agents Are Driving a New Wave of Database Growth

Supabase said it is now adding more than 1 million users and 4 million databases every month.

One of the most notable figures is that 70% of new databases created on the platform are now being created by agents or AI-driven tools.

This represents a major shift in how software infrastructure is being consumed.

AI coding tools such as Claude Code and Codex are enabling more people to build software, while increasingly capable coding agents are allowing those systems to create more sophisticated applications with less direct human involvement.

As the number of AI-generated applications increases, the infrastructure required to support those applications also grows.

For Supabase, that means more developers, more applications and potentially millions of additional databases being created and managed through its platform.

The company previously reported a 600% year-over-year increase in databases in June, when AI agents were already responsible for the majority of new database creation.

Supabase now wants to position itself as the backend infrastructure layer that developers and AI agents turn to whenever they need databases and other application services.

Building Infrastructure for Agentic Software

Traditional software development generally involves developers manually creating applications, configuring infrastructure and managing databases.

The rise of AI coding agents is changing that workflow.

Agents can now create applications, modify code and interact with backend infrastructure with increasingly limited human intervention. As this trend develops, infrastructure providers need to support a much larger number of software projects and databases.

Supabase believes this shift could create a new category of infrastructure requirements.

The company's platform already combines an open source Postgres database with authentication, storage, edge functions, real-time subscriptions and vector search.

It also operates a marketplace containing more than 100 integrated partner tools.

The company said more than 13 million developers currently use Supabase to build and scale applications.

Why Supabase Is Acquiring Turso

The funding announcement was accompanied by Supabase's acquisition of Turso.

Turso has built infrastructure designed to make it possible to provision large numbers of databases at low cost. Its architecture is particularly relevant to AI agents, which may require their own isolated databases for individual applications, tasks or workloads.

Supabase said an agent should be able to create a database instantly, while infrastructure platforms should be capable of launching enormous numbers of isolated databases without requiring a dedicated machine for every database.

Turso's technology supports on-demand per-agent databases both in the public cloud and in bring-your-own-cloud environments.

Its customers include Superhuman, Sauna.ai, CTO.new and Mastra.

The acquisition will allow Supabase to incorporate Turso's architecture into its broader platform while continuing to support the Turso platform.

Turso Team Joins Supabase

Glauber Costa, founder of Turso, will join Supabase as Head of Agentic Services.

Turso co-founder Pekka Enberg and the rest of the Turso team will also join Supabase.

Costa said his long-term goal had been to serve more than a billion databases for customers. He believes joining Supabase can bring that ambition closer because of the company's large developer community and expanding partner ecosystem.

The two companies share a strong focus on open source and developer experience, as well as an emphasis on solving difficult infrastructure problems.

That alignment makes the acquisition more than simply a technology transaction. Turso's architecture is intended to become part of Supabase's broader strategy for supporting agent-driven software development.

New Capital Comes Four Months After $500M Series F

The $150 million investment is notable not only because of its size, but also because of its timing.

Supabase raised $500 million in its Series F only four months earlier. The company is now securing another substantial round as demand for infrastructure supporting AI-driven software continues to accelerate.

The latest funding will be used to support continued product development around agent-driven databases.

Supabase also said the financing will provide liquidity for employees, which the founders view as an important part of building a strong company for engineers.

The participation of GIC, CapitalG, IronArc and SquarePeg gives Supabase additional institutional backing as it enters its next stage of expansion.

CapitalG general partner Derek Zanutto described Supabase as an important open infrastructure layer for the AI ecosystem and highlighted the company's growth among developers and AI agents.

Supabase's Bigger Bet on AI Agents

Supabase's latest moves point toward a broader shift in software infrastructure.

As AI agents become capable of creating applications themselves, infrastructure providers may need to support software being produced at a scale that traditional development workflows were never designed for.

That could mean dramatically more databases, isolated environments and backend services being created dynamically.

Supabase's acquisition of Turso is aimed directly at this challenge.

Instead of treating databases as infrastructure that developers manually provision and manage, the combined technology is designed to make database creation increasingly automatic and scalable for agent-driven workloads.

The company's strategy is therefore moving beyond being simply an open source Postgres platform.

Supabase is positioning itself as infrastructure for a world where AI agents become active participants in building and operating software.

What Comes Next

With $150 million in new funding and the Turso acquisition, Supabase now has additional resources to expand its agentic infrastructure strategy.

The company is seeing more than 1 million new users and 4 million new databases each month, while 70% of new databases are reportedly being created by agents or AI-driven tools.

Those numbers could continue to grow as coding agents become more capable and software creation becomes increasingly automated.

Supabase's challenge will be to ensure its infrastructure can scale alongside that growth while maintaining the developer experience and open source focus that helped it build a community of more than 13 million developers.

For now, the company's latest funding and Turso acquisition signal a clear bet: as AI agents create more software, the infrastructure underneath those agents could become one of the most important layers of the AI economy.
