Mercury is a San Francisco fintech that builds banking and financial software for startups and growth-stage companies. Through partner banks, it offers FDIC-insured checking and savings, corporate cards, treasury, venture debt, bill pay, and an API - aimed at founders who would rather not call a branch manager.
Henrique Dubugras is the Brazilian co-founder of Brex, the corporate card and spend management company he built from a Y Combinator pivot at age 21 into a $12.3B peak-valuation fintech unicorn - ultimately acquired by Capital One for $5.15 billion in 2026. He taught himself to code at 12 to avoid paying for a Korean MMO, sold his first payments company (Pagar.me) at 20 while processing $1.5B annually, dropped out of Stanford after 8 months, and found his billion-dollar idea by simply failing to get a credit card for his own startup. Now operating in stealth, he has said he found his 'calling' again.
