International business payments sit in a gap between consumer-grade transfer services and the corporate treasury infrastructure that only large companies can afford to operate. For European SMEs and mid-market companies that trade across borders, the options have historically been either expensive bank wire transfers with poor exchange rates or consumer transfer services not designed for business use. IBANFirst was founded in Paris in 2013 to fill that gap. Its platform provides European businesses with multi-currency IBAN accounts, competitive FX rates, mass payment capabilities, and the treasury tools needed to manage currency exposure — packaged for businesses rather than corporate treasuries. The IBAN-based structure means that international clients can pay in their local currency to a local account number, reducing friction on the receivables side while IBANFirst handles the conversion and settlement. The company expanded across Europe and attracted backing from investors including Xavier Niel, building a customer base of European businesses with significant international payment volumes. In the European B2B cross-border payment market, IBANFirst occupies the space between retail transfer services and enterprise treasury platforms — a segment that is large, underserved, and increasingly competitive as payment infrastructure becomes more accessible.
