Job Description
About Upflow
Upflow builds Financial Relationship Management (FRM) technology to help B2B companies get paid faster, more predictably, and with stronger customer relationships.
Today, the order-to-cash process 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, automation, and collaboration to turn receivables into a predictable and scalable engine.
FRM is the foundation, AI is the accelerator. Our platform leverages AI agents already operating on real financial data and customer interactions to help teams prioritize, automate, and scale decisions across every invoice and every relationship.
We serve 500+ companies across 30+ countries, including Lattice, Productboard, Veryable, 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.
It’s a perfect time to join if you’re looking for an exciting personal growth opportunity and international experience.
