About the Company

Upflow is the Financial Relationship Management (FRM) platform that helps B2B finance teams collect smarter and get paid by their customers faster, with AI agents working alongside the team.
The order-to-cash process is mission critical for businesses, yet it remains fragmented across tools, teams, and workflows. Upflow brings this entire process into one system — four products covering the cycle from invoice to cash (Insights, Collections, Payments, and Cash Application), with AI agents that work alongside the team and a shared intelligence layer underneath.
We serve 500+ companies across 30+ countries, including Vercel, Lattice, and 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.

Research shows that some candidates may hesitate to apply unless they meet every requirement.
