Supabase CEO Paul Copplestone says AI builders could drive 1.2 billion personal databases monthly, as Supabase surpasses 13 million users.
Supabase co-founder and CEO Paul Copplestone says the company has grown from about 3 million sign-ups to 13 million in a year, with revenue expected to quadruple and databases under management approaching 50 million. He describes Supabase’s shift from dashboard to API to code-first tools, as agents generate roughly 70% of new activity and non-engineers increasingly build software. Copplestone envisions people owning personal databases for finances, health, and other life data, with AI agents creating tailored apps on top. To serve everything from prototypes to petabyte-scale companies, Supabase is developing a lightweight tier after acquiring Turso. He also says coding-agent use among engineers rose from 10% to 60% in six months, requiring better error messages and extensive agent evaluations. His advice: choose durable markets, dogfood your product, and adapt quickly.
