Upflow

Upflow, founded in 2018 and a Y Combinator alumnus, builds a B2B payments platform designed to help finance teams collect outstanding invoices faster without damaging customer relationships. The platform automates the full accounts receivable workflow - from payment reminders and collections sequences to support for modern payment methods - removing the friction that typically surrounds late-payment follow-ups.

The company serves hundreds of B2B businesses, with customers including Lattice, Front, and ProductBoard. Its platform holds SOC 2 Type 2 certification, a baseline compliance requirement for finance software handling sensitive payment data. Upflow is backed by investors and counts Y Combinator among its notable backers.

Upflow operates as a distributed company with teams in New York and Paris, spanning three continents. Many team members bring direct experience working in or alongside finance functions, and the company's product direction reflects a focus on the practical frustrations of accounts receivable: slow collection cycles, awkward customer interactions, and fragmented tooling. Its target users are finance teams at B2B companies looking to modernize how they manage and collect payments.
