Hyperlayer, a London-based fintech startup, has raised £19.5 million in a series A funding round led by existing investor Flintlock Capital, valuing the company at £195 million post-money. The follow-on brings Hyperlayer’s total capital to nearly £50 million since October 2025 and will be used to expand product, engineering and implementation teams as the company pursues growth across the US, Europe and Asia-Pacific — a sign of continued investor appetite for banking middleware that upgrades legacy systems without ripping them out.
Why it matters
Banks face a difficult trade-off: modernise quickly or preserve the resilient core systems that keep payments and compliance running. Hyperlayer’s approach — a modular platform that sits above those cores — promises to shorten the timeline for new product launches while avoiding large, risky core replacements. That model is gaining traction with global banks and was part of why Hyperlayer was selected for Mastercard’s Start Path programme and has been engaged on transformation projects with Tier 1 institutions.
Inside the product
Hyperlayer describes itself as an intelligent banking platform with modular, customisable components that let banks, wealth managers, merchants and other firms launch new financial products without replacing back-end systems. The company points to real-world deployments, including the UK consumer app Hyperjar, as evidence its technology can support live, customer-facing services. The platform emphasises resilience and compliance by integrating with existing cores rather than acting as a full replacement.
Who are the investors?
The round was led by Flintlock Capital, with participation from Mouro Capital, Susquehanna Private Equity Investments, LLLP, and a mix of existing and new investors. The investment values Hyperlayer at £195 million post-money and brings total funding to nearly £50 million (about $66 million) since October 2025. As part of the deal, Joe Shamess, Co-Founder and General Partner at Flintlock Capital, will join Hyperlayer’s board.
In the announcement, Joe Shamess, Co-Founder and General Partner at Flintlock Capital, said:
Hyperlayer’s promise is clear. Banks, credit unions and other financial institutions must modernise at fintech speed without ripping out the core systems that protect them. A year on, that thesis is proven with world class customers and strong market pull. Leading this round, and joining the board, is us doubling down on where Rob and Paul take the business next.
The investor mix includes dedicated fintech backers and institutional participants that previously backed the company in its larger Q3 2025 round. That prior financing funded product scaling and international expansion, setting the stage for this follow-on.

Founder perspective
In the announcement, Rob Rooney, Co-founder and CEO at Hyperlayer, said:
We're fortunate to be backed by deep experts in fintech. They've watched us go from a standing start to mandates with global Tier 1 banks in three years. That's what's convinced them to back where the company goes next.
Hyperlayer also named two internal leadership moves. Louise Chan, a board director who has been serving as Chief Operating Officer, becomes Chief Commercial Officer, while Ben Helps, currently Chief Strategy Officer, will move into the Chief Operating Officer role.
In the announcement, Rob Rooney, Co-founder and CEO at Hyperlayer, said:
Both are exceptional colleagues and serious contributors to our success to date. Louise has been closing the deals that prove the model works. Ben has been building the operating discipline and strategy that let us deliver for clients and scale without breaking. These appointments recognise the roles they are already playing as Hyperlayer grows and gathers pace.
The bigger picture
This funding round underscores a continued investor focus on middleware and composable banking solutions that reduce the cost and risk of legacy modernisation. For UK and European banks, regulatory and operational constraints make wholesale core replacements unattractive, so solutions that integrate quickly have clearer commercial routes to revenue. Hyperlayer’s traction with established banks, membership in Mastercard’s Start Path and growing investor support reflect that dynamic.
The outcome also illustrates ongoing momentum in the UK fintech ecosystem: investors remain willing to fund companies that position themselves between legacy infrastructure and nimble fintech product development, and those companies are increasingly targeting international expansion as the next growth lever.
