Finexer Among UK’s Fastest-Growing Open Banking Firms

Finexer is an Open Banking infrastructure provider. It offers UK scaleups and mid-market platforms a unified API across three core areas:

Account Information Services Real-time transaction data, balances, and up to seven years of financial history across 99% of UK banks.

Payment Initiation Services Account-to-account payments and bulk payouts, reducing reliance on card networks that typically charge 1.5% to 3.5% per transaction and carry multi-day settlement delays.

Data Enrichment Standard Open Banking data converted into structured, categorised financial records with added merchant identity, spending categorisation, billing pattern detection, and location signals, processed in under 100ms across a database of more than 100 million merchants.

Platforms retain full control of their product and user experience. Finexer manages bank connectivity, FCA compliance, and the underlying data layer. Integration timelines are typically measured in weeks rather than months. Pricing is based on actual API consumption rather than pre-committed volume tiers.

Growth signals

Finexer was ranked #32 on the Sifted 100: UK and Ireland 2026 Leaderboard, which measures the region's fastest-growing startups by audited two-year revenue growth. Fintech was among the top-performing sectors on the list for the third consecutive year.

Finexer has also been shortlisted in two categories at the 2026 UK FinTech Awards: Best Open Banking Initiative and Innovator of the Year.

Growth has been driven by increasing inbound demand from product teams across accounting, payroll, and legal technology actively seeking Open Banking infrastructure that fits their development timelines without requiring them to build compliance architecture independently.

Ravi Ranjan, Co-Founder and CEO of Finexer, said:

"Eighteen months ago, most scaleups we spoke to saw Open Banking as a future consideration. Today, the focus is on how quickly they can go live. The inbound demand reflects a shift in how product teams approach financial infrastructure."

Finexer is backed by SFC Capital and the British Business Bank and is currently in its growth round. 

Where the market is heading

The conditions for broader adoption are now in place. Regulatory frameworks are established, UK bank coverage is near-universal, and infrastructure providers like finexer are reducing integration and pricing barriers.

For accounting, fintech, and SaaS platforms, the decision is increasingly shifting from whether to adopt Open Banking to how quickly it can be deployed in production environments.

Finexer is authorised by the Financial Conduct Authority under the Payment Services Regulations 2017 (FRN 925695) as an Authorised Payment Institution.
