Supabase, the open-source developer platform once touted as a Firebase alternative, has just raised an impressive $80 million in its Series C funding round, led by Peak XV and Craft Ventures. This new injection of capital brings the company’s total funding to $196 million and solidifies its growing dominance in the database world, as more enterprises and startups flock to its developer-friendly, Postgres-centric platform.
While the company hasn’t disclosed its valuation, co-founder and CEO Paul Copplestone emphasized that this was an “up round,” signaling an increase in market value. Interestingly, despite this fresh capital, Copplestone revealed that Supabase has only recently dipped into reserves from its 2022 Series B funding—another $80 million round—demonstrating fiscal prudence even as the company expands its offerings.
The latest surge in interest for Supabase comes largely on the back of the AI boom. Supabase was among the first platforms to offer support for the pgvector extension, a critical tool enabling Postgres databases to store and query vectors. This capability is vital for developers building generative AI applications that rely on large language models and unstructured data. “We were the first to offer pgvector, which gave us an early advantage. AWS came later, and we’ve since worked closely with them to promote usage industry-wide,” Copplestone shared. Today, about 10% of active databases on Supabase power AI use cases, underscoring the platform’s crucial role in this growing field.
Supabase’s rise has been swift. In just four years, it has amassed over 900,000 sign-ups, an unprecedented level of organic growth for a developer platform. While it began as an open-source alternative to Google’s Firebase, it has since positioned itself as a Postgres-first platform—a move that capitalized on the soaring popularity of Postgres databases. “People adopt us because we’re easy to use like Firebase, and also because we’re built on Postgres, which is growing in popularity,” Copplestone explained. “Combine those two factors, and we’ve become the easiest Postgres offering.”
What sets Supabase apart isn’t just its flagship Postgres database service. The company also provides a suite of complementary tools, including authentication services, real-time subscriptions, edge functions, storage, and vector embeddings. Many enterprises and startups begin their journey with Supabase by leveraging just one of these products, particularly its popular authentication service, before exploring the full breadth of its Postgres-based ecosystem.
Supabase’s growing traction with enterprises is notable. Developers at companies like Meta, Netflix, Microsoft, and GitHub Next have turned to Supabase to power experimental and cutting-edge applications. Furthermore, 40% of startups in the most recent Y Combinator cohort are using the platform—a statistic that showcases its broad appeal across different business stages.
Avra Capital, led by former YC Growth Fund Director Anu Hariharan, also participated in the Series C round, alongside existing investors Coatue, Felicis, and Y Combinator. Hariharan lauded Supabase’s momentum, stating, “Supabase has redefined database management with its open-source Postgres platform. Its organic adoption among developers is unprecedented, and with the recent Vercel marketplace partnership, we believe Supabase is fast becoming the preferred choice for developer-friendly database solutions.”
With its latest round of funding, Supabase plans to continue enhancing its product suite and expanding into enterprise markets. The question isn’t whether Supabase can keep up with its current momentum—it’s how much further it can push the boundaries of what a developer platform can do.
