Company History and Business Evolution

Yolt Technology Services traces its origins to 2015, when ING Group launched a fintech lab in Amsterdam to explore open banking opportunities. The initial project, codenamed “Yolt,” focused on creating a personal finance management app for consumers. By 2017, the lab had developed a robust API layer that enabled account aggregation across multiple banks. Recognizing the technology’s potential, ING spun off Yolt Technology Services as a separate entity in 2020, with €50 million in seed funding from ING and external venture partners. The company’s first major milestone came in 2021 when it launched its Payment Initiation Service (PIS), processing over 1 million transactions in its first year. In 2022, YTS acquired Finnovate, a London-based open banking consultancy, expanding its presence in the UK market. The following year, it secured a full Electronic Money Institution (EMI) license from the Dutch Central Bank, enabling direct issuance of IBANs and e-money wallets. By 2024, Yolt Technology Services had expanded to 12 offices across Europe, including Berlin, Paris, and Warsaw, and exceeded €100 million in annual recurring revenue (ARR). Key product launches include the Data Enrichment Engine (2023), which uses machine learning to categorize transactions with 98% accuracy, and the Fraud Detection Suite (2024), which reduced chargeback rates by 40% for beta customers. The company’s evolution reflects a strategic shift from consumer app to B2B infrastructure provider, mirroring the maturation of the open banking market. Today, YTS serves over 500 enterprise clients, including 10 of the top 20 European banks, and processes more than €2 billion in payments annually. Its history is marked by continuous innovation, strategic acquisitions, and a commitment to regulatory leadership, positioning it as a cornerstone of Europe’s open banking ecosystem.

Mission, Vision, and Core Corporate Values

Yolt Technology Services’ mission is to democratize access to financial data, enabling any organization to build secure, compliant, and innovative financial services. The company envisions a future where open banking is the default — a seamless, transparent, and user-controlled data economy. To achieve this, YTS adheres to four core values: Trust Through Transparency — ensuring every API call is auditable and compliant with PSD2 and GDPR; Performance at Scale — delivering sub-100ms response times even during peak loads; Collaborative Innovation — co-creating products with clients and partners in an open marketplace; and Responsible Growth — balancing commercial success with ethical data use and financial inclusion. These values are embedded in every product decision, hiring process, and client engagement. For example, the company’s open-source contribution program encourages engineers to publish internal tools that benefit the broader developer community, fostering trust and collaboration. Moreover, YTS publishes an annual Transparency Report detailing security incidents, data requests, and uptime statistics, reinforcing its commitment to openness. The mission and values attract top talent who seek purposeful work at the intersection of finance and technology.

Business Strategy and Future Roadmap

Yolt Technology Services has a three-pronged growth strategy: Deepen European Coverage — expanding regulatory compliance to all EU member states and obtaining additional licenses in Switzerland and the United Kingdom; Extend Product Suite — launching variable recurring payments (VRP) and open finance products for mortgages and pensions by 2026; and Scale Through Partnerships — integrating with leading enterprise resource planning (ERP) platforms like SAP and Oracle to embed open banking into corporate treasury workflows. The company plans to invest €30 million in artificial intelligence and machine learning over the next two years, focusing on predictive analytics for cash-flow forecasting and fraud prevention. A key initiative is the “Yolt Connect” ecosystem, a white-label platform allowing banks to offer open banking services under their own brand. Future milestones include processing €10 billion in payment volume by 2027 and achieving a 95% market share among European neobanks. YTS also aims to go public via an IPO by 2028, assuming market conditions allow. The roadmap reflects a vision of becoming the essential infrastructure for Europe’s financial data economy.
