About company
Upflow
Upflow builds the reference cash collection platform to help B2B companies get paid faster, more predictably, and with stronger customer relationships. Today, the order-to-cash process is mission critical for businesses, yet it remains fragmented across tools, teams, and workflows. Collections, payments, and reconciliation are often manual, reactive, and disconnected from the rest of the business. Upflow brings this entire process into one system — combining data, agentic automation, collaboration, and financial services to turn receivables into a predictable and scalable engine. We serve 500+ companies across 30+ countries, including Vercel, Lattice, Productboard, and are backed by leading investors including Y Combinator, Hedosophia, Hexa, and Lorimer. With teams across the US and Europe, we’re building a category-defining company at the intersection of finance, payments, and AI.
