Supabase's Valuation Skyrockets to $5 Billion in Just Four Months - Here's How They Did It

Supabase's Meteoric Rise

It's been a whirlwind year for Supabase, the vibe-coding world's database of choice. On Friday, Supabase announced it raised a fresh $100 million Series E at a $5 billion valuation, led by Accel and Peak XV. This milestone comes just four months after closing its $200 million Series D at a $2 billion valuation, also led by Accel.

Rapid Fundraising Timeline

• Series D: $200 million at $2 billion valuation (April 2025)
• Series C: $80 million led by Peak XV and Craft Ventures (September 2024) - PitchBook estimated a post-money valuation of around $765 million

In total, Supabase has raised $380 million in just one year, with a more than 500% valuation increase assuming PitchBook's Series C estimates are accurate. The company has now raised a total of $500 million.

Origins and Growth

Open source database service Supabase was founded in 2020 by CEO Paul Copplestone and CTO Ant Wilson. It started as a Y Combinator startup offering developers a Postgres-based open source alternative to Google's Firebase. Supabase combines Postgres with other enterprise-grade open source tools for features like:

• Authentication
• Auto-generated APIs
• File storage
• Vector toolkit (essential for many AI apps)

Supabase simplified setting up a database to just a few clicks, making it a popular backend for vibe-coding tools that write apps with natural language prompts. It's increasingly used as the database of choice for:

• Figma
• Replit
• Cursor
• Claude Code
• Lovable and Bolt

Community Involvement

Because Supabase is open source and supported by a community of developers—claiming 4 million developers as users—the company is allowing community members to buy stock as part of this Series E funding.
