About Upflow

Upflow revolutionizes the way B2B businesses get paid, unlocks owed cash reserves, and empowers companies to grow better.

We are a product-led SaaS startup, launched in 2018 and trusted by hundreds of companies across the US and EMEA, including Lattice, Front, Iziwork, ProductBoard, and more. We're also backed by leading investors (YCombinator, eFounders, Hedosophia) and top business angels from N26, Square, Mercury, Uber, and Netsuite.

This is an amazing opportunity to work and learn in a fast-growing Fintech and an international environment — we have offices in the US (NYC), EU (Paris) and are very remote friendly.
