Paul Copplestone is CEO and co‑founder of Supabase with a decade of experience building developer platforms and scalable web applications. He combines product leadership with hands‑on engineering, contributing across the stack—from sign-up UIs to core libraries like supabase-js and auth-js and backend systems such as supabase/realtime. His technical footprint spans Postgres schema and policy design, OAuth and multi‑tab session handling, and an unusual deep dive into realtime replication using Elixir/Phoenix and the Cainophile library. A repeat founder (Nimbus For Work, ServisHero) and YC alum, he focuses on growing Supabase as the open‑source Firebase alternative while still shipping tests, docs, and core infrastructure code.
