Henrique Dubugras and Pedro Franceschi (Brazilian ex-Pagar.me founders) launched Brex in 2017 through Y Combinator, building corporate cards, expense management, and business banking for startups. After peaking at a $12.3B valuation in 2022, the distributed Delaware C-corp endured 11% layoffs that October and a 20% cut in January 2024 before refocusing on enterprise (Q1 2025 enterprise revenue grew 70%, NRR exceeded 130%, customers include OpenAI, DoorDash, Airbnb). Brex hit operating-cash-flow positive in October 2025 and shipped its Agent Mesh and Brex Assistant for autonomous finance workflows. Capital One agreed in January 2026 to acquire Brex for $5.15B, closing April 7, 2026.
