The UK has been one of Europe’s leading fintech markets for years. London, in particular, has become a major home for startups working in digital banking, payments, lending, wealth management and financial technology.
But the UK’s newer fintech startups are now going beyond traditional digital banking. Many are using artificial intelligence, stablecoins, automation and new financial tools to solve specific problems for businesses, investors and consumers.
The funding market has also become more competitive. UK fintech investment fell during the first half of 2026, but startups using AI continued to attract investor interest. According to KPMG, AI-focused fintech companies received £445 million across 79 deals in H1 2026.
Here are some of the UK fintech startups worth watching in 2026.
Velocity is a UK fintech startup focused on stablecoin payments and financial infrastructure.
The company is building technology that helps businesses move money internationally using stablecoins. Its platform also connects digital assets with traditional financial systems.
In 2026, Velocity raised $38 million in Series A funding. The round was led by Dragonfly and FirstMark, with participation from investors including Coinbase Ventures, Ripple and Capital One Ventures.
The company is targeting businesses that need faster ways to handle international payments, treasury management and settlement.
Why it stands out: Velocity is working at the intersection of fintech, payments and digital assets instead of competing directly with traditional digital banks.
Nevis is building an AI-powered platform for wealth management.

Nevis has attracted major investors, including Sequoia Capital, ICONIQ and Ribbit Capital.
The company is part of a growing fintech trend where AI is being used to help financial professionals save time and handle routine tasks.

The London-based fintech provides multi-currency financial services for people who live, work or do business internationally.
In 2026, nsave received electronic money institution authorisation from the UK’s Financial Conduct Authority. This was an important step because it gives the company more control over its payment and account services.
Founded in 2022, nsave has reported more than 500,000 users who move around $1 billion each year.
The company is solving a common problem for people who work or live internationally: managing different currencies without depending completely on traditional banks.

The company says it now serves more than 100,000 UK households and has raised more than £15 million in equity funding.
Nous is not trying to replace a traditional bank. Instead, it aims to become a useful financial tool that helps people manage the services they already pay for.
Why it stands out: With household expenses remaining a major concern for consumers, tools that help people save money can have strong demand.

The company is developing banking and payment services for businesses that operate across multiple countries and currencies.

Its focus comes at a time when more businesses are selling products and services internationally. These companies need financial systems that can handle different currencies, markets and payment methods.
Why it stands out: TuningBill is targeting the growing need for easier and faster cross-border financial services.
The UK fintech industry is becoming more mature. The market is no longer focused only on digital banks and mobile payment apps.
New startups are now building specialised financial products that solve specific problems.
AI is expected to remain one of the biggest areas of growth. KPMG’s 2026 figures show that investors are still putting money into AI-focused fintech companies, even as overall fintech investment becomes more cautious.
Stablecoins and blockchain-based payment systems are another area to watch. Companies such as Velocity are exploring how digital currencies could make international payments and treasury management faster.
At the same time, companies such as nsave, Outpost and TuningBill are working on the growing need for cross-border financial services.
The UK’s fintech startup market is changing quickly. New companies are not simply trying to become the next digital bank. Instead, they are focusing on AI, stablecoins, wealth management, international payments, alternative lending and automated financial services.
Velocity, Nevis, Adfin, nsave, Nous, Capsa.ai, Outpost, TreeCard, BLEND Network and TuningBill each represent a different part of this new fintech market.
As the sector continues to grow, startups that can combine strong technology with clear business value and regulatory readiness could have the best chance of standing out.
