In this Top 10, FinTech Magazine explores the fastest growing neobanks, featuring giants like Nubank, Revolut and Monzo
A digital-first mentality has started to emerge as firms and institutions shift operations online.
A hallmark of the digital era comes in the form of neobanks – representing the fight for brick and mortar institutions over online-only services.
With disruptors offering various benefits that rival traditional banks, which titan will feature on top?
This ranking reflects a new era of maturity in the sector, where hyper-growth is now paired with robust profitability.
Latin American titan Nubank and European powerhouse Revolut showcase the sheer scale achievable through aggressive international expansion and diversified product suites.
Meanwhile, specialised players like Allica Bank and Starling prove that focusing on underserved segments, such as established SMEs and mortgage holders, provides a sustainable path to success.
- Curve
Company founded: 2015
Based in: London, UK
CEO: Shachar Bialick
Curve, acquired by Lloyds Bank, is a platform that consolidates a user’s entire financial life into one card and app.
Its success stems from its unique ability to ‘supercharge’ existing bank accounts rather than replacing them.
By offering features like ‘Go Back in Time’ – allowing users to switch the card used for a past transaction – and providing competitive FX rates, Curve has carved out a distinct niche that appeals to multi-card holders globally.
- Varo Bank
Company founded: 2015
Based in: San Francisco, US
CEO: Gavin Michael
Varo Bank made history as the first all-digital consumer fintech to receive a national bank charter in the US.
This milestone allowed it to offer the security of a traditional bank – including FDIC insurance – with the agility of a startup.
Varo’s innovation lies in its mission-driven approach to financial inclusion, providing high-yield savings and ‘Varo Advance’ cash flows to help Americans manage liquidity without the predatory fees often associated with legacy institutions, supported by a recent US$123.9m growth investment in its Series G funding round.
- Tandem Bank
Company founded: 2013
Based in: Blackpool, UK
CEO: Neil Chandler
Tandem Bank has pivoted successfully to become the UK’s leading ‘green bank’.

By integrating green finance into a seamless digital experience, Tandem has proven that profitability can align with environmental impact.
In 2025, the bank reported continued revenue gains, demonstrating the resilience of its specialised lending model in a challenging economy.
- Atom Bank
Company founded: 2014
Based in: Newcastle, UK
CEO: Mark Mullen
Atom Bank was a pioneer in the UK neobanking scene, launching as the first bank built exclusively for mobile.
Unlike peers that focused on current accounts, Atom prioritised high-value lending products such as mortgages and business loans.
This focus on the ‘fin’ as much as the ‘tech’ has led to impressive stability.
By keeping overheads low and focusing on a transparent, app-based mortgage process, Atom has successfully challenged legacy lenders.

This strategy has paid off – Allica reached profitability in record time, reporting a pre-tax profit of approximately £29.9m (US$38m) for 2024, proving significant value exists in serving complex SME needs.
- SoFi
Company founded: 2011
Based in: San Francisco, US

This Productivity Loop strategy has solidified its position as a dominant force.
