Journee tops Deloitte UK Technology Fast 50 ranking
Deloitte has announced the winners of its 2025 UK Technology Fast 50 awards that recognise and rank the 50 fastest-growing technology companies in the UK, based on average revenue growth over a three-year period. The awards are sponsored by Citi, Oracle NetSuite, Erevena, Binderr and Octopus Ventures.
The 2025 Fast 50 winners have a collective average three-year growth rate of 1,905% and generated total revenues of £2.41 billion in 2024/25.
Kiren Asad, lead partner for the Deloitte UK Technology Fast 50 programme, said: “For nearly three decades, the Fast 50 has highlighted rapidly growing and innovative technology companies across the UK. And 2025 is no different with this year’s cohort having grown around 20 times on average over three years, showing that the UK tech scale-up sector is continuing to demonstrate remarkable resilience amidst global economic shifts.
“I extend my warmest congratulations to all the companies recognised in the 2025 Deloitte UK Technology Fast 50. Their achievements are a testament to the vibrant spirit of the UK tech sector – creating jobs, driving economic growth and shaping a better future for the UK and beyond.”
Fast 50 2025 winners
Business-to-consumer travel company Journee has been named as the overall winner of the Fast 50 awards, having achieved a three-year growth rate of 10,171% to the year 2024/25. The London-based business, founded in 2019, matches travellers with a surprise trip based on their travel style through a matchmaking process, eliminating the need for customers to research, plan, or book the trip themselves. The traveller finds out where they're going at the airport.
Ed Tribe, Journee Co-Founder & CEO, said: "We’re on a mission to help people step outside their comfort zone and fall in love with somewhere new. This recognition is a powerful testament to the unwavering belief of our team in this mission, despite the unprecedented challenges of the past few years.
“From a small start-up facing a global pandemic, we've grown to send over 16,000 travellers, with significant expansion into the US market. This Fast 50 award fuels our commitment to empowering more individuals to explore the world with convenience, curiosity, and trust, validating our innovative approach to travel."
In second place is Monument Bank Limited, a London-based fintech company with a three-year growth rate of 9,518%. The challenger bank helps professionals, entrepreneurs and ambitious savers grow their wealth.
Ian Rand, CEO of Monument Bank Limited, said: "Being featured in the Deloitte Technology Fast 50 is an important milestone for everyone at Monument. It reflects how quickly we are growing by focusing on what matters most: our clients. They trust us with billions in savings, and we are building the technology and service to become the world's leading bank for mass affluent clients."
London continues to dominate the rankings
The majority of Fast 50 companies continue to be headquartered in London, with 70% based in the capital. The number of companies outside of London remains the same this year.
Midlands-based Previsico took fourth place (up from 14th in last year’s ranking) with a three-year growth rate of 3,624%. The environmental technology business provides a hyperlocal flood intelligence platform, combining advanced rainfall data with on-site sensors to generate property-level flood forecasts and warnings for surface water, river, and coastal flooding.
Other standout regional performances include eighth-placed ValStream Limited, who provide a Software-as-a-Service (SaaS) platform and consulting services for procurement and repair management. Based in the South East, the company’s three-year growth rate totalled 2,805%.
Scotland-based fintech LendingCrowd also made this year’s top ten, with a three-year growth rate of 2,792%. The company facilitates business loans for small and medium-sized enterprises (SMEs) by matching them with investors seeking to earn returns on their capital.
Cambridge-based decarbonisation company Levidian placed 16th in the main ranking, and scooped this year’s CleanTech award. Now in its third year, the CleanTech award recognises climate technology companies within the Fast 50 for their contribution to the UK’s net zero target.
Asad added: “The distribution of Fast 50 companies reflects the broader challenges of scaling outside of London and the South East. To unlock the full potential of the UK’s tech ecosystem, greater regional support - including funding, infrastructure and talent development, will play a crucial role in enabling more companies nationwide to scale.”
London-based Dexory Limited, who placed 21st in this year’s ranking, came out on top in the Women in Leadership category. This category recognises companies within the Fast 50 that are either led by a female* CEO or have a woman in their founding team.
US most attractive for expansion
The ranking coincides with a new Deloitte survey of UK tech company CEOs, highlighting their international expansion strategies.
The survey found that the US continues to be the dominant global market target, cited by 61% of respondents (compared to 62% in 2024). Europe’s attraction dipped from 53% in 2024, to 47% this year, with the Middle East moving from 32% in 2024, to 22% this year.
More companies are also prioritising domestic consolidation over cross-border growth – from 8% in 2024, to 12% in 2025.
Keynote speaker at the Fast 50 awards, Alex Depledge MBE, the Chancellor of the Exchequer’s Entrepreneurship Adviser, said: “What I love about the Deloitte Fast 50 is that it celebrates the brave ones - the founders who take an idea, back themselves, and build something brilliant.
“These businesses aren’t just growing fast; they’re fuelling jobs, innovation, and energy across the UK. That’s why it’s so important we keep this country the best place to start and scale a business. Huge congratulations to all the winners - they’re proof of what happens when ambition meets action.”
