Finexer has been named #32 on the Sifted 100: UK & Ireland 2026 Leaderboard, which recognises the 100 fastest-growing startups across the UK and Ireland. The ranking is backed by the Financial Times and based on audited two-year revenue growth.
This year’s list features some of the most ambitious technology companies in the region. The average two-year CAGR across the 100 companies has reached 248%, up from 171% in 2024 and 204% in 2025. Fintech remains the top-performing vertical for the third year running, with 36 companies featured. Being named amongst them is a recognition we do not take lightly.
What this reflects
Finexer was built to solve a specific problem. UK businesses were losing £19.6B annually in payment processing fees. £28B in working capital was sitting locked in payment delays. 94% of UK firms were struggling to access real-time financial data. Open Banking existed as a solution to all of this – but the infrastructure to access it was built for enterprise, not for the accounting platforms, payroll providers, legal technology companies, and ERP systems that needed it most.
We set out to close that gap. A single API giving mid-market platforms access to verified bank data, account-to-account payments, and bank-grade verification – across 99% of UK banks, under FCA authorisation, at usage-based pricing that works for platforms at every stage of growth.
The Sifted 100 ranking reflects the commercial response to that positioning. Demand has been driven almost entirely by inbound – platforms actively searching for Open Banking infrastructure that works at their scale.
The wider context
A new report from Open Banking Limited and EY confirms that Open Banking is already generating £2bn in annual economic value across the UK, with a pathway to £43bn at full maturity. The UK recorded 24 billion successful Open Banking API calls in 2025, up 27% year-on-year.
The infrastructure buildout that makes this value accessible to mid-market platforms is what Finexer is focused on. This ranking is a milestone on that journey.
From our founder
“This recognition is a reflection of the platforms we serve and the problem we are solving together. Mid-market businesses have needed Open Banking infrastructure that works at their scale for years. We are building it. The market is responding.”
