Brex was founded by two Brazilians from Rio - Henrique Dubugras and Pedro Franceschi. Together, in their teens, they launched and sold a fintech company called Pagar. They then moved to SF and applied to YCombinator.
At YC, Michael Siebel asked the founders - if you could build anything, what would you build? The founders replied - A business bank.
The problem was something they faced first hand. Despite receiving investment, startups struggled to get a corporate credit card.
Traditional banks were slow, manual, with archaic digital interfaces. Worst of all, they didn’t know how to underwrite early-stage businesses with no credit history.
The founders, Henrique & Pedro scoped out their MVP to a single sentence - build a corporate credit card for startups. They focused on features like fast sign up, higher limits without personal guarantees, and automated receipt capture.
The founders focused on friends and family who were either founders or finance people at small companies.
Since they graduated from YC, they also got a bunch of early customers from the YC community.
They also scraped LinkedIn for contacts of thousands of foreign founders (who typically lack FICO scores and struggle to get credit cards) & emailed them if they would be interested in the product. They had 100 pilot customers doing this.
They iterated based on feedback from these users & Brex delivered its first cards to the pilot customers in four months.
One of the things Henrique did to raise funds was to keep meeting & building relationships with VCs.
They updated them on developments and were always kept in the loop. They didnt stop or start any stage. It was a continuous process.
