Company profile
researched Aug 2026Unnax is a Spanish fintech providing banking-as-a-service infrastructure that lets companies build and embed financial services without obtaining their own regulatory licenses. Its modular API platform covers user validation and onboarding, fraud prevention, creation of bank accounts and virtual wallets, IBAN issuing, payment initiation and collection, bank aggregation, and analysis of financial data for scoring processes.
Unnax is described as the first Spanish fintech to hold a triple license from the Bank of Spain, covering account information services (AISP), payment initiation services (PISP) and status as an Electronic Money Institution (EMI). At the time of its 2024 acquisition, it served more than 60 financial services customers in banking, consumer finance, fintech and software across Spain and Latin America, and offered financial data aggregation in Spain and Mexico.
Since the acquisition Unnax operates within Powens Group, which combines Open Finance data access with embedded banking and payments on a single platform. The Unnax brand was retained for the Iberian and Latin American markets, while Powens serves as the reference brand elsewhere in Europe; Powens Group's EMI licence is held via Unnax, through the legal entities Unnax Regulatory Services EDE SLU and Unnax Payment Systems SLU.
Founding story
Unnax was founded in 2016 by Julián Díaz-Santos Hernández and Jordi Pérez Roselló to address demand for as-a-service financial technology, providing the banking technology and regulatory authorization that companies need in order to launch new financial services.
Business model
B2B provider of licensed financial infrastructure, delivering banking, payment and data-aggregation capabilities to other companies through a single API so that they can embed financial services without holding their own regulatory authorizations.

Latest developments
In April 2024 Powens finalized its acquisition of Unnax after approval from Banco de España, creating Powens Group under CEO Bertrand Jeannet with a mixed executive team.
