About Paul Copplestone
Paul Copplestone is co-founder and chief executive of Supabase, an open-source application platform built around PostgreSQL. He grew up in New Zealand and worked in Australia and Southeast Asia. He co-founded the marketplace ServisHero in 2015 and also co-founded Nimbus For Work.
In December 2019 he pitched Ant Wilson on building an open-source database company. They began building in February 2020 and joined Y Combinator's Summer 2020 batch. Crunchbase lists his location as Singapore.
Supabase has since raised a US$500 million Series F at a US$10 billion valuation, according to NZ Herald.
Public databases count his angel investments differently. Crunchbase lists 20 investments. PitchBook lists 54 investments, 42 portfolio companies and 10 exits. Tracxn lists 48 companies. The figures differ by source and are not confirmed by him.
PitchBook dates recent deals from April 2025 (Tldraw) to mid-2026. Co-investors across his deals include Y Combinator and Guillermo Rauch.
AgentMail is building email inboxes for AI agents. It announced a $6M seed round on March 10, 2026, led by General Catalyst. Y Combinator and Phosphor Capital also took part, as did angels including Paul Graham and Dharmesh Shah. The company's announcement names Copplestone as an angel and identifies him as CEO of Supabase. The Lounge deals desk lists two AgentMail seed entries (2026-03 and 2026-09). Only the March 2026 round is confirmed in public sources.
Command Code builds a coding agent that learns a developer's coding preferences. It announced a $5M seed round in February 2026. Preston-Werner Ventures led the round, and Copplestone is listed among the participating individuals. Crunchbase also shows him in the company's earlier pre-seed round.
PitchBook also lists Mem0, Firecrawl and Lovable, each dated mid-2025. Tracxn names Mistral AI as a notable investment.
The visible portfolio leans toward developer tools, infrastructure and software for builders. Tracxn lists Enterprise Applications and Enterprise Infrastructure as his top sectors. His deals span the United States, the United Kingdom and other countries. The deals shown here are mostly seed or earlier. He has not published a check size or a statement of what he looks for, so none is given here.
