Supabase: $100 Million Series E At $5 Billion Valuation Raised For Postgres Development Platform

By Amit Chowdhry • Oct 3, 2025

Supabase, an open-source Postgres development platform, has announced the close of a $100 million Series E funding round, valuing the company at $5 billion. The round was led by Accel and Peak XV, with participation from Figma Ventures and other returning investors. This latest round comes just four months after its Series D funding round, bringing the total funding to over $500 million.

In a move that reflects its deep commitment to the open-source community, Supabase plans to allocate a portion of the Series E funding for community members to co-invest alongside institutional partners. This initiative will allow developers and advocates of open-source software to participate directly in the company’s growth, reinforcing Supabase’s community-first ethos.

The funding caps off a huge year for Supabase, which has become the preferred backend platform for AI-driven development. More than 100,000 customers now rely on Supabase, including over half of the most recent Y Combinator cohort and major enterprises such as PwC, McDonald’s, and GitHub Next. The platform’s appeal lies in its ability to rapidly spin up backends that respond instantly to AI-generated commands, making it a natural fit for developers working with tools like Cursor and Claude Code.

Supabase currently serves over 4 million developers worldwide, offering a scalable and intuitive solution for building modern applications. With the new capital, the company will accelerate development of “Multigres,” an enterprise-grade version of its platform designed for large, data-intensive workloads. To lead this effort, Supabase has hired Sugu Sougoumarane, co-creator of Vitess —a widely respected open-source database technology used by companies such as YouTube.

Sougoumarane joins a growing team of industry veterans at Supabase, including core contributors to Postgres, the co-founder of NGINX, and founders from several Y Combinator-backed startups. Together, they are building a next-generation infrastructure platform that blends the reliability of Postgres with the flexibility and performance needed for AI-powered applications.

How the funding will be used: With this Series E funding, Supabase is poised to deepen its role as a foundational layer for modern software development, empowering developers and enterprises alike to build faster, smarter, and more scalable systems.

KEY QUOTES:

“Our community is what makes Supabase special, and it’s a priority to give them the opportunity to co-invest in what we’re building. With the new capital we’ll continue serving our community of over 4 million developers while building open source tools to scale Postgres.”

Paul Copplestone, co-founder and CEO of Supabase

“Supabase is scaling with clarity and conviction while redefining what it means to build applications with AI. With millions of developers, enterprise validation, and a team of entrepreneurial builders, Supabase is emerging as the defining database for the next generation of software.”

Arun Mathew, partner at Accel

“We’re excited to co-lead Supabase’s Series E alongside Accel. Supabase started with managed Postgres but is now evolving into a platform company. Their incredible developer-first mindset has made them a critical enabler for hundreds of thousands of new AI startups globally, powering the AI supercycle for millions of developers. This is our third consecutive investment since co-leading their Series C a year ago, reflecting our deep conviction in Paul, Ant, Rory and their leadership team. We’re thrilled to continue this enduring partnership as Supabase scales to its next phase of growth.”

Peak XV’s Shailendra Singh

“We invested in Supabase at the seed because developers shouldn’t have to choose between speed and scale. Today, the ability to build in a weekend and scale to millions is not just possible, it’s routine with Supabase. This new financing aims to accelerate Supabase’s efforts to become the backend for everyone, from startups to some of the most demanding, data-intensive enterprise workloads.”
