Santander CIB provided a senior credit facility as part of FintechOS's $28 million combined equity and debt financing. The London-headquartered B2B fintech and AI platform for banks and insurers also raised equity from existing shareholders Bek Ventures, IFC, Cipio Partners and Molten Ventures.
The size of the debt sleeve was not disclosed. The only announced figure is the combined $28 million across equity and debt. FintechOS said the capital will be used to support its US expansion, serve European financial-institution clients and scale delivery of its AI-native platform.
Founded in Romania in 2017 by Teodor Blidarus, its chief executive, and Sergiu Negut, FintechOS is headquartered in London and also has offices in Bucharest and the US. The company sells to banks and insurers, positioning its platform around digital product delivery and AI-enabled financial-services infrastructure.
Blidarus described Santander CIB's support alongside existing investors as a vote of confidence and said the capital allows the company to pursue US potential without compromising profitability discipline. Cyril Desouza, chief financial officer, said profitability was the result of deliberate multi-year discipline, adding that the combination of profitability and growth enabled FintechOS to take a round structured this way.
The financing follows a $60 million raise in 2024. Earlier financing included a $10 million IFC investment in 2021, a $60 million Series B in 2021 and a $14 million Series A in 2019. FintechOS has raised more than $150 million in total. The company said it reached operational profitability in H1 2026, with recurring revenue growth of about 40% and US revenue up 130% year on year.
UK Companies House filings for FintechOS Technology UK Ltd show an outstanding charge in favour of Banco Santander, S.A. created on 22 May 2026. That filing may indicate the Santander facility closed before the announcement, but it does not disclose an amount.
A separate charge in favour of Kreos Capital VI (UK) Limited was created on 11 January 2022 and remains outstanding.
