Supabase raises $500m at $10.5bn on 600% database growth driven by AI agents

Summary

Supabase, the open-source Firebase alternative and Y Combinator S20 alumnus, raised $500m in a Series F on 4 June 2026 at a $10.5bn post-money valuation. GIC led; Accel, Y Combinator, Craft, Felicis, Coatue, Stripe (its second cheque into Supabase) and Salesforce Ventures also participated. The raise doubles the $5bn valuation the company reached in an October 2025 Series E, in eight months. Growth is AI-native: the platform recorded 600% year-over-year database growth, and Anthropic's Claude Code is Supabase's single largest driver of new database creation since early 2026. The company counts 250,000+ paying customers and nearly 10 million developers. 59% of Y Combinator's W26 batch and over 1,000 YC alumni built on Supabase in production.

The split

US and India open-source press frame the raise as validation that AI agent workloads are causing a structural step-change in database demand, separate from the vibe-coding hype cycle. Stripe's re-investment is read as infrastructure-layer consolidation: payments and data co-investing in the same agentic stack. No critical international voice disputes the demand numbers; the remaining debate is whether open-source database valuations can hold up against cloud-native hyperscaler alternatives.

By the numbers

  • $500m, Series F size.
  • $10.5bn, post-money valuation (doubled from $5bn in October 2025).
  • 600%, year-over-year growth in databases on the platform.
  • 250,000+, paying customers.
  • ~10 million, developers on the platform.
  • 59%, share of YC W26 batch building on Supabase.
  • Claude Code, single largest new-database driver in 2026.

Why it matters

Supabase's raise makes the infrastructure layer beneath AI-coded apps the next major venture asset class. The Claude Code correlation directly links AI Coding Startups investment with backend database demand, showing that coding AI adoption has moved from experimentation into production workloads at scale.

What to watch

  • Whether Supabase files for an IPO in 2026 or 2027 alongside Databricks and Stripe.
  • How Stripe uses its infrastructure stake as agent payment flows grow.
  • Competition from Firebase/Firestore, PlanetScale and Neon as hyperscalers add AI-agent database features.
