Supabase has raised $500 million at a $10.5 billion valuation, underscoring growing investor confidence in open source PostgreSQL infrastructure as AI coding tools drive demand for integrated backend platforms.
Supabase has secured $500 million in Series F funding at a post-money valuation of $10.5 billion, highlighting the growing importance of open-source infrastructure in the AI software era. The round was led by GIC, with participation from existing investors Accel, Y Combinator, Craft, Felicis, Peak XV, and Coatue. Stripe increased its investment, while Salesforce Ventures joined as a new investor.
Built on PostgreSQL, one of the world’s most widely used open-source databases, Supabase has evolved from an open-source Firebase alternative into a full backend platform designed for AI-era application development. The company combines database services, authentication, APIs, storage, real-time capabilities, serverless functions, and AI-ready data tools within a single platform.
The funding comes as AI coding tools such as Cursor, Claude Code, and Codex enable faster software development, increasing demand for backend infrastructure that can reliably support generated applications.
A key part of Supabase’s AI strategy is its use of PostgreSQL and pgvector, an extension that enables vector embeddings for semantic search, recommendation systems, retrieval-augmented generation (RAG), and enterprise AI assistants. By keeping traditional application data and vector data within the same Postgres environment, Supabase aims to simplify AI application development.
Alongside the funding announcement, the company introduced Multigres v0.1 alpha, described as a scalable operating system for Postgres. The project is designed to address PostgreSQL scalability challenges while preserving its open-source foundation for larger enterprise workloads.
The announcement signals growing confidence that open-source PostgreSQL infrastructure will play a central role in the next generation of AI-powered applications.
