Originally founded as Nordic API Gateway in 2011, the company rebranded to Aiia in 2020. In 2021, Aiia was acquired by Mastercard to strengthen its open banking capabilities. Aiia operates a platform that aggregates financial data from thousands of banks, allowing third-party developers, fintechs, and other businesses to build services on top of this data. Their core services include Account Information Services (AIS), which provides access to aggregated account data, and Payment Initiation Services (PIS), which enables direct account-to-account payments. The company's mission is to empower businesses and consumers by creating simple and secure access to financial data.
