The Backend for the AI Era
Our investment in Supabase.

Summary
Supabase is the open-source Postgres platform giving developers a complete backend — database, auth, storage, realtime, and more — through a single SDK. We’re thrilled to participate in their Series F.

Building a modern backend has always been more painful than it should be. For most developers, it means stitching together a database from one vendor, an auth system from another, object storage from a third, and then writing the glue code to make them talk to each other. The result is complexity that slows down early-stage development, creates maintenance overhead at scale, and introduces points of failure at every seam. Supabase was built to eliminate this complexity with a single open-source platform that gives developers a complete Postgres backend, with auth, storage, realtime, and edge functions included, wired together from day one.
Supabase sits at the convergence of two powerful secular trends. First, Postgres has cemented itself as a leading database standard for developers, driven by its open-source model, extensibility, and absence of vendor lock-in. StackOverflow’s 2025 developer survey shows PostgreSQL at 58.2% professional developer usage, a 7-point jump since 2024.
Second, the rise of AI coding tools (Claude Code, Cursor, Lovable, v0, etc.) has created an entirely new distribution channel, and Supabase has emerged as one of the most common backends within it. This creates a compounding defensibility that can’t be easily replicated simply by standing up managed Postgres. As these tools wire Supabase in, the integration surface deepens across auth, storage, edge functions, and agent workflows. Switching costs accumulate at the platform level, not the database level.
Supabase was founded in 2020 by Paul Copplestone and Ant Wilson. Paul, a third-time founder and lifelong community builder, came up with the idea for Supabase after migrating off another platform where spinning up a backend meant juggling four separate vendors with no clean way to tie them together. The idea resonated with his friend Ant, who also has deep expertise in large-scale storage systems. Together they built a real-time Postgres layer that bundled the whole stack. They strategically built it in the open since day one — curating best-in-class open-source tools where they existed (Postgres, PostgREST) and writing and open-sourcing their own where they didn’t (e.g., a real-time Elixir server that streams Postgres changes over WebSockets). The bundled, fully self-hostable stack took off organically. Five years later, more than seven million developers have signed up and Supabase has become the go-to backend for a generation of builders.
The product that sits at the center of Supabase’s momentum is genuinely differentiated. Supabase wraps a full, unmodified Postgres instance with auth, row-level security, storage, realtime features, edge functions, and vector search in a single integrated SDK. This means a solo developer can now ship a full-stack application without cobbling together separate services. An AI coding tool can wire up a complete backend in a single step. That bundled simplicity is why developers say Supabase is their default choice, and why switching costs, once auth and realtime are integrated, are high. Further, Supabase is making ambitious bets on the enterprise and scale problems. Multigres, led by Sugu Sougoumarane (co-creator of Vitess, which helped scale YouTube’s database), brings transparent horizontal sharding to Postgres, removing the scale ceiling that has historically pushed growing companies toward elsewhere. OrioleDB, led by Alexander Korotkov (a top-10 Postgres contributor), replaces Postgres’s legacy storage engine with a modern architecture that delivers significantly higher throughput. Together, these two initiatives are building the bridge from a beloved developer tool to an enterprise-grade infrastructure platform.
Supabase’s growth reflects a strategy that’s working on two fronts: deepening its developer community while steadily moving upmarket to serve larger enterprise customers. The customer base ranges from individual developers and YC startups — 55% of the latest batch builds on Supabase — to a growing number of tech scale-ups and enterprises. Strategic partnerships with Vercel, Figma, and Bolt continue to expand the platform’s reach and deepen the distribution flywheel.
All said, we’re proud to join GIC, Coatue, Accel, Peak XV Partners, Felicis, and others in backing Paul, Ant, and the entire Supabase team. The combination of Postgres momentum, AI distribution, a product developers genuinely love, and a team making the right long-term technical bets is an exciting and rare convergence. We believe Supabase is building the foundational infrastructure layer for how software gets built in the AI era, and we’re thrilled to now be part of their story.
