Supabase Raises $150 Million and Buys Turso, as Agents Now Create 70% of Its New Databases

Supabase, the company behind the open-source Postgres development platform, announced \$150 million in new funding led by Singapore sovereign wealth fund GIC, with Alphabet's independent growth fund CapitalG, IronArc and SquarePeg participating. The raise lands just four months after a \$500 million Series F, and part of it will fund liquidity for employees.

The number that explains the round is not the raise. Supabase says it is now adding more than 1 million users and 4 million databases per month, and that roughly 70% of new databases are created by agents or AI-driven tools. In June the company reported a 600% year-over-year increase in databases, at which point agents were already deploying the majority of new databases on the platform.

Alongside the funding, Supabase said it is acquiring Turso, a database company built for agentic workloads, for an undisclosed sum. Turso's architecture is based on SQLite — small enough to run on phones and wearables — and is designed to let a platform launch enormous numbers of isolated, on-demand databases without provisioning a dedicated machine for each one. That is precisely the pattern that breaks when every agent wants its own store for collected files, intermediate state and instructions.

Turso's customers include Superhuman, Sauna.ai, CTO.new and Mastra. It supports embeddings and encrypts each database page slightly differently to reduce the value of a single breach, and it offers deployment both in the public cloud and in bring-your-own-cloud environments. Founder Glauber Costa will join Supabase as head of agentic services, alongside co-founder Pekka Enberg and the rest of the team; the Turso platform will keep running with a migration path into the Supabase ecosystem.

"Agents are spinning up millions of databases to power the prototypes, explorations, dashboards, and apps they're building," Supabase co-founder and CEO Paul Copplestone wrote. "This new pattern, at this massive scale, requires an evolution in database infrastructure." CapitalG general partner Derek Zanutto framed the bet more bluntly, calling Supabase "the critical open infrastructure layer powering the AI revolution."

Supabase was founded in 2020 and says more than 13 million developers use its platform, which bundles Postgres with authentication, storage, edge functions, real-time subscriptions and vector search, plus a marketplace of more than 100 integrated tools. The acquisition also pairs with Supabase Compute, a service for hosted sandboxes that keep long-running agents alive, announced the same day.

What this means: the coding-agent boom is quietly rewriting the economics of the database layer. When the primary consumer of infrastructure is software writing software, provisioning overhead — not query performance — becomes the constraint, and vendors that can spin up an isolated database in milliseconds win by default. Supabase is buying that capability rather than building it, and GIC's check signals that sovereign funds now treat agent infrastructure as core infrastructure, not a trend bet.
