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’s funding arc has moved from a Series A for an open-source alternative to Firebase, through an $80M Series B and a $100M Series E, to this much larger round. The new valuation is double the valuation reported with the October 2025 financing.
Coverage before the announcement had already identified GIC as the expected lead and framed the round at roughly the same size and valuation. Its completion confirms that investors are assigning greater strategic value to backend tooling as AI-assisted application creation expands.
First-order effects
Supabase gains $500M of additional capital and a high-profile lead investor, giving it substantially more capacity to invest in its backend platform and pursue growth from a stronger valuation base.
The round resets Supabase’s market benchmark at a $10B pre-money valuation, strengthening its position as an independently funded open-source Firebase alternative.
Second-order effects
Backend-platform rivals, including Google’s Firebase, face a better-capitalized competitor for developers building and operating AI applications; differentiation around developer workflow and managed infrastructure becomes more consequential.
The financing validates the infrastructure layer beneath AI-assisted software creation, potentially directing more investor and customer attention toward services that turn rapid front-end prototyping into deployable applications.
Third-order effects
If AI-assisted and “vibe-coded” applications continue to increase software output, the bottleneck may shift from writing interfaces to reliably provisioning databases, authentication, and other backend capabilities—raising the strategic value of platform providers in that layer.
The result could be a more concentrated market for developer infrastructure, even as open-source products remain an entry point: large funding rounds can help open-source vendors commercialize and scale managed services rather than compete solely on code availability.
The trend: This is part of the shift from financing AI models alone toward financing the developer-infrastructure platforms needed to build, deploy, and operate the applications created with AI assistance.
@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]

Salesforce Ventures is proud to invest in @supabase: the new backend for the AI era 🚀 Building a modern backend has always been more painful than it should be: stitching together a database from one vendor, auth from another, storage from a third, and glue code to hold it all [im…
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]
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…
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!
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/...
