Supabase’s Series E: An Era-Defining Database
Supabase CEO and co-founder Paul Copplestone likes to say that “it doesn’t matter what you start, it matters what you finish.” That conviction drove the launch of Supabase, a Postgres-based platform built to address the lack of tools to quickly build scalable applications. Five years later, Supabase has grown by appealing to developers for its speed and to enterprises for its reliability.
Supabase is now one of the most credible challengers in the database market. The company now serves over 100,000 customers, spanning half of the latest Y Combinator batch and enterprises like PwC, McDonald’s, and 1Password.
As developer workflows change, Supabase has become a fixture in AI-native builds. It works seamlessly alongside tools like Claude Code and Cursor, making it easy to spin up backends that respond to AI commands. Its gentle learning curve and clean UX attract both skilled developers and low-code builders alike, with Bolt, Figma, and Lovable all selecting it as the default backend for projects on their platforms.
This new capital will fund the development of Multigres, a highly scalable version of the Supabase platform designed for large enterprises and data-intensive applications. To lead Multigres, Supabase has hired Sugu Sougoumarane, who built Vitess while at YouTube to solve the platform’s MySQL scaling challenges before co-founding PlanetScale.
Scaling up hasn’t meant leaving the developer community behind. Paul and co-founder Ant Wilson have kept Supabase’s four million developers at the center of every decision. The company holds meetups in dozens of countries and just hosted its first user conference, Supabase Select. All the while, Paul has stayed in the weeds, combing through online mentions of “Supabase” and jumping into threads to help users troubleshoot problems or take advantage of new features. (If you see @kiwicopple reply to you on X or GitHub, yes, it’s really him.)
Behind that balance of growth and community is one of the strongest technical teams in database infrastructure. In addition to Sugu Sougoumarane, over 30 database and open-source founders have joined Supabase, including Postgres core contributors, the co-founder of NGINX, and founders of various Y Combinator companies.
We’re co-leading Supabase’s Series E alongside Peak XV. What makes this round notable is that every participant is an existing investor, underscoring strong conviction in the momentum and enterprise value the company is creating. True to its open-source DNA, Supabase also gave community members the opportunity to invest alongside institutional partners, reflecting the same balance of conviction and inclusion that has fueled its rise.
Supabase is defining the database standard for the AI era, built with and for the developer community. We’re proud to be partners in that mission.
