Romanian-founded FintechOS has closed a $28 million (approximately €26.5 million) funding round in combined equity and debt to accelerate its push into the United States and consolidate its footprint across Europe.

Existing backers Bek Ventures, IFC, Cipio Partners, and Molten Ventures provided the equity portion, while Santander CIB supplied a senior debt facility, bringing the London-headquartered firm's total funding to nearly €170 million since its inception in 2017.

The capital injection marks a calculated shift for the company, which acts as an AI-native technology layer over aging core infrastructure. Banks and insurance companies are notoriously sluggish when it comes to modernizing these foundational systems built decades ago, leaving many financial institutions struggling to launch new products or meet modern consumer expectations.

A deliberate pivot from efficiency to expansion

For the past few years, the broader technology sector has been obsessed with capital efficiency and runway preservation. FintechOS played this game exceptionally well, securing $60M Series B+ in 2024, and achieving profitability in the first half of 2026. During the period, the firm also grew its recurring revenue by 40 percent year-on-year and boosted operational EBITDA by more than 102 percent.

Cyril Desouza, Chief Financial Officer at FintechOS, explains that this outcome was highly intentional. "Reaching profitability was not an accident, it was the outcome of a deliberate, multi-year effort to get our cost base, our margins and our delivery practice right before we pushed harder on growth again," he points out. Desouza adds that this discipline is now paying off, allowing the business to make a confident shift back into a high-growth phase.

The mix of debt and equity is particularly telling. Rather than relying entirely on a dilutive priced equity round, FintechOS is using debt capital to scale, a financing route that becomes significantly more accessible once a software company crosses the threshold into profitability.

Targeting the American core banking market

The true engine behind this impressive 2026 performance is the US market, which saw a staggering 130 percent growth over the past year. FintechOS is not resting on these laurels; the leadership team is targeting more than 200 percent year-on-year growth in the US over the next twelve months.

To steer this aggressive expansion, the company is overhauling its governance structure in the region. This includes appointing a new US board and a new chairman to navigate strategic partnerships. A critical component of this strategy relies on deep integrations with established core banking providers. By partnering with heavyweights like Finxact, which is part of Fiserv, and Finastra Phoenix, FintechOS is opening the door to a massive pool of bank and credit union clients that are desperate for modernisation.

"Growth and profitability go hand in hand, not at the expense of one another," notes Teo Blidarus, Founder and CEO of FintechOS. He stresses that the support from Santander CIB and other investors provides the capital to chase the extraordinary potential in the US without compromising the discipline that led to their current financial stability.

European consolidation and agile delivery pods

While the US represents the fastest-growing frontier, FintechOS is actively consolidating its strong position across Europe. The company is securing new clients in the UK while expanding ties with systemic organisations like BRD Groupe Societe Generale, Admiral, CEC Bank, and Bankinter. The firm expects a record year overall, anticipating that more than 20 new financial institutions will adopt its platform by the end of 2026.

This client acquisition is largely driven by a new approach to product delivery. The company's FintechOS 8 platform features an AI copilot named Dex, which allows non-technical users to configure financial products directly. To maximise this capability, the company is rolling out "forward-deployed" agile client pods. Each pod consists of a technical consultant and an engineer who work intimately with a client's product team to dramatically cut time to market and lower the total cost of ownership.

As traditional banks face mounting pressure to innovate quickly, this blend of AI-native tooling and embedded engineering support offers a compelling alternative to massive core migration projects. The upcoming FintechOS Elevate '26 executive conference in London this October will likely serve as the prime stage for Blidarus and his team to prove that their profitable growth model is the blueprint for the future of financial software.
