Upflow

We're building the reference payment platform for B2B businesses in Europe. Getting paid on time remains a significant problem for B2B businesses. We're on a mission to revolutionise how companies manage their outstanding payments. To do this, we're building a fully fledged payment platform from scratch - think Stripe but for traditional (non-tech) businesses. It's an extremely complex and multi-faceted problem which affects almost 500,000 businesses across Europe. We run on React / GraphQL / Node / Express / Postgres. We're still really small (3 developers) and are looking for great hackers to work across the stack on problems ranging from payments, security, product and data.
