What We Do
Modulr has grown to become the leading provider of embedded payments to organisations across the UK and Europe. Embedded payments is a new category that permits payments to become part of organisations’ technology stack, upgrading them to become payments companies themselves. Modulr enables over 200 enterprise customers and thousands of SME customers to embed account creation, payment out, reconciliation of payment in, card issuing and many open banking and similar features into their own business process flows via API calls and webhooks into Modulr’s cloud platform. Core to Modulr’s success has been the platform itself, Modulr’s regulatory status as an EMI in the UK and Europe, its connections to payments and other financial service schemes, its ability to operate at scale, and its compliance rigour. Today Modulr handles over £100bn of annualised payment volume and its platform handles, on average, 30 API calls per second
