"Came from" is the job each person left to join, from their public career history; internships are left out. Start dates aren't public for Jack Lindsey and Trenton Bricken.

Leaders who worked at Stripe

Four of the 15 people on Anthropic's own leadership page (as of 2026-10-18) worked at Stripe at some point, plus Kate Jensen, who runs the Americas. Some went somewhere else in between, so the arrivals chart above, which counts only the job people left to join, shows fewer.
