San Francisco, CA – October 3, 2025 – Supabase, a leading open-source Postgres development platform, today announced the successful closure of a $100 million Series E funding round, elevating the company’s valuation to an impressive $5 billion. This significant investment, co-led by prominent venture capital firms Accel and Peak XV, also saw participation from Figma Ventures and other returning investors, signaling strong confidence in Supabase’s trajectory and its increasing influence in the tech ecosystem. This latest funding infusion comes just four months after its Series D round, pushing Supabase’s total capital raised to over $500 million.
The new capital is earmarked to accelerate Supabase’s mission to serve the most data-intensive enterprises and further its position as the ‘preferred backend for AI-driven development.’ A key initiative is the development of ‘Multigres,’ an enterprise-scale version of its platform designed to handle large, complex data workloads. To spearhead this ambitious project, Supabase has brought on board Sugu Sougoumarane, the acclaimed co-creator of Vitess, an open-source database technology widely adopted by companies like YouTube. Sougoumarane joins a growing team of industry veterans, including core Postgres contributors and the co-founder of NGINX, reinforcing Supabase’s commitment to robust, scalable solutions.
Supabase has rapidly emerged as a critical enabler for the burgeoning AI startup ecosystem, powering the ‘AI supercycle’ for millions of developers. The platform is increasingly utilized alongside AI coding tools such as Cursor and Claude Code, demonstrating its versatility and responsiveness to modern development needs. Paul Copplestone, co-founder and CEO of Supabase, emphasized the company’s community-centric approach: “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.”
Arun Mathew, a partner at Accel, lauded Supabase’s impact, stating, “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.” Shailendra Singh, Managing Director at Peak XV, echoed this sentiment, highlighting Supabase’s evolution: “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.”
