It\u2019s been a whirlwind year for the vibe-coding world\u2019s database of choice: Supabase. On Friday, Supabase announced that it raised a fresh $100 million Series E at a $5 billion valuation, led by Accel and Peak XV. This is just four months after closing its $200 million Series D at a $2 billion valuation,<\/a> led by Accel.<\/p>\n And that Series D was just seven months after raising an $80 million Series C<\/a> led by Sequoia spinoff Peak XV and David Sacks\u2019 Craft Ventures at an undisclosed valuation. PitchBook estimated Supabase was valued at around $765 million in that deal, post-money.<\/p>\n So that\u2019s $380 million raised in a year and a more than 500% valuation step up, assuming PitchBook\u2019s estimates of the Series C valuation are in the ballpark. Supabase has now raised a total of $500 million, it says.<\/p>\n Open source database service Supabase was founded in 2020 by CEO Paul Copplestone and CTO Ant Wilson (pictured above), a few years before the LLM-powered vibe-coding craze spawned. It was originally a Y Combinator startup that offered developers a Postgres-based open source alternative to Google\u2019s Firebase. Firebase is a database that was also designed to power AI apps.<\/p>\n Supabase combines Postgres with other enterprise-grade open source tools for features like authentication, auto-generated APIs, file storage, and a vector toolkit (necessary for many AI apps).\u00a0It simplified the difficult parts of setting up a database down to a few button clicks. Consequently, it became a popular back end for vibe-coding tools \u2014 which write apps with natural language prompts \u2014\u00a0like fast-growing Lovable<\/a> and Bolt. It is increasingly used as the database of choice for Figma<\/a> and other uber popular AI coding tools like Replit,<\/a> Cursor<\/a>, and Claude Code<\/a>, it says.<\/p>\n Interestingly, because Supabase is open source and supported by a community of developers \u2014 claiming 4 million developers as users \u2014 it is allowing community members to also buy stock as part of this Series E funding, the company said.<\/p>\n Techcrunch event<\/p>\n
