Hi! We are Billie, the leading provider of “Buy Now, Pay Later” (BNPL) payment methods for businesses, offering B2B companies innovative digital payment services and modern checkout solutions. We are here to transform and upgrade the operating system of B2B Payments. Thus, we enable businesses to pay and get paid on their own terms, having the same frictionless and flexible experience as consumers are used to nowadays. To do so, our solutions are based on proprietary, machine-learning-supported risk models, fully digitized processes and a highly scalable tech platform. This makes us a deep-tech company building financial products, not the other way around. We love building simple and elegant solutions and we strive for automation and scalability. Our vision to create new freedom through innovation has attracted exciting strategic partners and highly experienced investors, making us join forces with Klarna and securing an outstanding $100 million Series C funding round nearly quadrupling our previous valuation. Our investors include VCs such as Dawn Capital, Creandum, Picus and SpeedInvest.

Join us to create the future of B2B payments!
