John Collison

In Stripe's 2025 annual letter, co-authored with brother Patrick, John Collison called for regulatory, capital markets, and labor reforms to revive European prosperity. He criticized European regulations like GDPR for imposing disproportionate compliance costs on small firms that favor large incumbents, and argued Ireland's proliferation of 303 unaccountable agencies since 2000 has stalled infrastructure and housing.

John Collison has donated approximately $233,000 to Democratic candidates and organizations as of August 2024, including contributions to Kamala Harris and the Democratic National Committee. This represents personal political giving, not company contributions.

In 2024, John Collison launched a five-year health initiative in Ireland, funded in the millions, aimed at halving the time it takes to diagnose cerebral palsy in newborns. The initiative represents a significant personal commitment to healthcare access in his home country.

In April 2023, John Collison adopted over 40 abandoned horses in Ireland to aid a rescue operation facing closure due to capacity issues. His intervention prevented euthanasia and funded rehabilitation of the animals through his personal resources.

John Collison is a founding donor of Arc Institute, a $650+ million initiative co-founded by his brother Patrick Collison in 2021 to reform scientific research funding. The institute provides scientists with 8-year renewable research terms without requiring external grant applications.
