Supabase, which provides backend tools for building AI apps, raised a $500M Series F led by GIC at a $10B pre-money valuation, up from $5B in October 2025

Context & Ripple Effects
Supabase has progressed from an open-source Firebase alternative automating backend work to a heavily funded platform for application builders. Its prior Series E valued it at $5B in October 2025, after earlier rounds that emphasized developer adoption and database creation.
The reported Series F doubles that valuation in roughly eight months and brings GIC in as lead investor, signaling that backend infrastructure is being valued as a key layer in the AI-app development stack rather than as a narrow developer-tool category.
First-order effects
Supabase gains $500M of fresh capital to fund its backend platform and a $10B pre-money valuation that materially raises the stakes for its execution after the $5B Series E.
GIC becomes the lead investor in a company positioned around infrastructure for AI application building, while Supabase’s existing open-source Firebase-alternative positioning gains a stronger financial backing.
Second-order effects
Google Firebase and other backend-tool providers face a better-capitalized open-source-oriented competitor, increasing pressure to retain developers as AI-assisted development lowers the effort required to launch new applications.
As more teams use AI-assisted or “vibe coding” workflows to create apps, demand can shift toward managed databases and backend services that reduce the operational work left after code generation.
Third-order effects
If this financing reflects sustained demand rather than a single-company re-rating, value in AI software may accrue not only to model providers and coding tools but also to the infrastructure layers needed to operate the resulting applications.
The pattern could widen the divide between backend platforms with developer ecosystems, managed-service capacity, and financing to scale, and smaller tools that cannot translate open-source adoption into durable infrastructure businesses.
The trend: AI-assisted software creation is increasing the strategic importance—and investor value—of the backend infrastructure that turns generated application code into deployable services.
Huge shout to all the helpers, contributors, feedback givers, triagers and more who show up every day to make this ecosystem better. Supabase wouldn't be what it is without your help!
We led @Supabase's Seed and Series A. Five years in, they're the open source Postgres platform powering the majority of AI app builders — and 9 million developers strong. As agents reshape how software gets made, Supabase has become the default backend underneath it. Proud to [im…
Backed @supabase at Series B because we believed they would win by becoming the default developer backend. Now at $10.5B, nearly 10M devs, and agents deploying the majority of databases - Postgres is the foundation of the agentic era !! 🐘 💚 🧡 https://x.com/...
Congratulations to @Supabase on raising $500M at a $10.5B valuation! When Felicis first backed Supabase at Series B, the company had one of the strongest developer growth curves we'd seen; it's was one of the fastest growing on GitHub. The thesis was that open source, [video]

@multigres And our community continues to grow. There are nearly 10M builders (and their agents) using Supabase now. Thank you to everyone who's contributed code, shared feedback, and built with Supabase. Now back to work :) [image]
