FintechOS raises $28M Series B for AI-native financial product operations platform

FintechOS Raises $28M Series B

FintechOS, a provider of an AI-native platform for unified financial product operations, has raised $28 million in Series B funding. The round was announced on September 21, 2026.

What FintechOS Does

FintechOS provides an AI-native platform for unified financial product operations. The platform lets banks, insurers and other financial institutions design, price, launch and service products in a single operational flow on top of their existing core systems.

The key architectural point is that FintechOS sits on top of existing core systems rather than requiring replacement. For financial institutions with long-lived core banking and policy administration systems, that positioning lowers the barrier to adoption and shortens deployment timelines.

Company Background

FintechOS was founded in 2017 and is headquartered in London and New York, with an office in Bucharest. The company serves banks and insurers across the US and Europe.

Named customers include:

• Societe Generale
• Admiral
• Howden Group

That customer base spans banking and insurance across two major regions, which is notable for a company operating in the financial infrastructure layer where procurement cycles are long and reference customers carry significant weight.

Investors

The Series B included participation from:

• Bek Ventures
• International Finance Corporation
• Cipio Partners
• Molten Ventures

No lead investor was disclosed.

The presence of the International Finance Corporation among the investors is notable given the company's focus on financial institutions across the US and Europe.

Why This Matters for Financial Infrastructure

Banks and insurers have historically managed product operations through a patchwork of core systems, spreadsheets, manual pricing processes and bespoke integrations. Launching a new product or repricing an existing one often requires coordination across multiple disconnected systems, which slows time-to-market and increases operational risk.

FintechOS's proposition is to unify that flow — design, price, launch and service — into a single operational layer that works on top of whatever core systems an institution already runs. Adding an AI-native dimension to that layer reflects where financial infrastructure is heading: not just digitizing processes, but applying intelligence to product decisions and servicing.

The company's customer roster suggests it has moved past early adopter territory. Societe Generale, Admiral and Howden Group are established institutions with demanding compliance, security and integration requirements. Serving them across both banking and insurance in the US and Europe indicates a platform that has been hardened across multiple regulatory environments.

What the Funding Supports

At $28 million, this Series B gives FintechOS capital to expand its presence across the US and Europe, deepen its AI-native capabilities and continue serving its existing bank and insurer customers. The round also provides resources to pursue additional enterprise deployments in a segment where implementation quality and referenceability drive the sales cycle.

Acquisition Angle

For acquirers in financial software, core banking, insurance technology or enterprise AI, FintechOS represents a growth-stage asset with several attributes worth tracking:

• Strategic positioning. Sitting on top of existing core systems makes the platform complementary to incumbent core vendors rather than competitive with them — a profile that often attracts strategic interest.
• Cross-segment reach. Coverage of both banking and insurance broadens the addressable market and the set of potential acquirers.
• Enterprise validation. Named customers including Societe Generale, Admiral and Howden Group provide third-party proof of enterprise readiness.
• Geographic footprint. Operations across London, New York and Bucharest give the company delivery capacity across major financial centres.

Financial infrastructure has been an active area for both strategic acquisitions and private equity roll-ups, particularly for platforms that unify product operations without forcing core replacement. FintechOS's Series B gives it the capital to scale that position further before any such conversation becomes relevant.
