Folio is a B2B fintech and procure-to-pay platform built specifically for the hospitality industry, primarily hotels and their restaurants.

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.
