Why did Brex make the decision to offboard 20,000 small business customers?

Brex made this strategic decision after realizing they couldn't provide exceptional service to small businesses while focusing on their core startup customers. When analyzing their competitive edge, they found they lacked structural advantages in providing credit to small businesses compared to traditional banks, which was what these customers primarily valued. Simultaneously, their core customers needed more sophisticated software and automation tools to manage spending at scale. This created a clear direction - one market pulling them away (small businesses) and another pulling them in (startups). Despite being a painful PR moment with communication missteps, this focus allowed Brex to better serve their target customers rather than making promises they couldn't fulfill effectively.
