Clarus Networks today announced that it ranked among the UK’s 50 fastest-growing technology companies in the 2025 Deloitte UK Technology Fast 50, a ranking of the 50 fastest-growing technology companies in the UK.

Clarus Networks also received two special recognitions – as a Women in Leadership winner and as the top-ranked communications company in this year’s awards.
Derek Phillips, Co-founder and Managing Director of Clarus Networks, credits the company’s growth to its focus on delivering innovative connectivity solutions and exceptional service. He said:
“This recognition from Deloitte reflects the dedication and innovation that define our team. We’ve built our business around solving real-world connectivity challenges for organisations across the globe, and being named both a Fast 50 and Women in Leadership winner highlights the strength of our vision and our people.”
Debra Phillips, Co-founder and Commercial Director, added:
“We’re immensely proud to be recognised not just for our growth, but for our leadership values. Diversity and inclusion have been at the heart of our journey, and this award reinforces our belief that empowering women in technology leads to stronger, more innovative companies.”
The 50 fastest-growing UK technology companies, as ranked by Deloitte, generated £2.41bn in combined total annual revenues in the year 2024/25. The Deloitte UK Technology Fast 50 recorded an average three-year growth rate of 1,905%.
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.
