About Finto
Finto is on a mission to reinvent how enterprises run their finance operations. Starting with AI-powered automation for accounts payable, we eliminate manual invoice handling, supplier chasing, 3-Way-Matching and ERP data entry. Backed by Y Combinator, we’re building the future of enterprise accounting.
Our mission is to free the world’s finance teams from repetitive, low-value tasks so they can focus on impactful work. That starts with building a place where everyone can do their best work. Whether you’re building on our platform, partnering with our customers, or shaping our story: We just make things finance teams want.
