Cambridge CleanTech company Levidian at the double in Deloitte UK Fast 50

Two other companies from the region invaded a London-dominated show – Duxford-based FinTech company Monavate in 23rd with 1314 per cent growth and 44th based Cambridge software specialist Obrizum Group with 662 per cent growth over the period. London had the top three fastest growers and six of the top seven!

Based in Mercer's Row, Cambridge, Levidian is on a mission to decarbonise the world's most carbon-intensive industries. Powered by its patented LOOP technology, the business provides a comprehensive decarbonisation service that converts carbon liabilities into a competitive advantage, solving the dilemma between decarbonisation and business performance.

London-based travel company Journee topped Deloitte’s 2025 UK Technology Fast 50 awards with a three-year growth rate of 10,171 per cent to the year 2024/25.

The combined revenue of the Fast 50 companies totalled £2.41 billion in 2024/25, with an average revenue growth of 1,905 per cent over the three years under review.

Julian Rae, Deloitte Cambridge office senior partner and Head of Emerging Growth for the UK firm 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.

“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.”

Deloitte research found that the US continues to be the dominant global market target, cited by 61 per cent of respondents (compared to 62 per cent in 2024). Europe’s attraction dipped from 53 per cent in 2024, to 47 per cent this year with the Middle East moving from 32 per cent in 2024, to 22 per cent.

More companies are also prioritising domestic consolidation over cross-border growth – from eight per cent in 2024 to 12 per cent in 2025.
