Deloitte is calling on the most innovative and rapidly growing technology scale-ups across the Thames Valley to apply for the firm’s prestigious UK Technology Fast 50. Applications for this year’s programme are officially now open.
The annual ranking celebrates the fastest-growing tech companies across the UK, based on average revenue growth over a three-year period. Last year’s Technology Fast 50 winners had a collective average three-year growth rate of 1,905% and generated total revenues of £2.41 billion in 2024/25.
Eighth in last year’s ranking, ValStream Limited provides 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%.
David Stevens, ValStream CEO, said: “ValStream being recognised as one of the UK’s fastest growing companies and as South East’s regional winner is a wonderful reflection of both the ambition of our company and relentlessness of our team.
“I would strongly encourage any technology business that is pushing boundaries and driving real innovation to apply for this year’s Deloitte Technology Fast 50. Being part of this programme has not only validated what we are building at ValStream but has opened doors and connected us with a community of equally ambitious companies. If you believe in what you are building, put yourself forward, recognition like this can be a powerful catalyst for what comes next.”
Lee Waterson, Deloitte Private Region Lead for the South East, said: “Securing a spot on the Fast 50 ranking offers a unique opportunity to create new opportunities for investment and partnerships; elevate your profile and credibility within the competitive tech landscape; and position your company as an employer of choice for top tech professionals within the Thames Valley and more broadly the UK.
“If your company is on a growth trajectory, pushing boundaries, and ready for that next big leap, then this is something you should be looking at – don’t miss the chance to showcase your achievements and elevate your brand on a national stage.”
