Langstone, South Wales, 7th November 2025 — de Novo Solutions today announced that it ranked number 13 in the 2025 Deloitte UK Technology Fast 50, and was named the highest-ranked business from across the South West and Wales region. Rankings are based on percentage revenue growth over the last three years. de Novo Solutions grew 2,284% during this period.

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.”
Dave Rozier, Deloitte partner based in Wales, said: “To be included in Deloitte’s Technology Fast 50 requires consistent revenue growth over a three-year period, so being one of the 50 fastest growing technology companies in the UK is a great achievement. de Novo Solutions should be applauded for its strategic vision and commitment to innovation.”
Mark Sweeny, Founder and Group Chief Executive at de Novo, credits the company’s innovative solutions and team commitment with its exceptional growth.
“To be ranked 13th fastest growing tech company in the UK and named Wales’ fastest growing by Deloitte is absolutely fantastic – especially after making the Sunday Times 100 earlier this year. This is all down to our team’s relentless focus on delivering real transformation for clients, not just cookie-cutter implementations. And we’re immensely proud to be proving Welsh tech can compete at the highest level.”
