About Stacks

Stacks is building an AI-native platform that reinvents how modern finance teams run the monthly close. The opportunity is massive: every growing company depends on accurate, timely financial data, yet most are still operating with tools and workflows built for a different era. In just two years, we’ve grown from a team of 2 to 30+ and are on a rapid trajectory. We’ve raised a $23m Series A led by Lightspeed Venture Partners, and we were recently recognised as one of Harmonic’s Hottest Startups of 2026. We’re already trusted by leading European scale-ups including Pleo, Freetrade, and Motorway. Our team is a blend of finance, product, and technical experts from top-tier companies like Uber, Plaid, Miro, Mollie, and Bunq, united by the drive to create a game-changing solution. We’re a team that is deeply customer-obsessed, plays to win, and isn’t afraid to take big, bold bets. We move fast, hold a high bar, and are committed to growing together as we scale.
