London-based MSP Redcentric jumped a whopping 16 spots in this year's ranking off the back of 51 per cent annual revenue growth. Meanwhile, its revenue run rate grew by 75 per cent according to its most recent set of filings.

The firm reflected on the past year as an ‘inflection point' having added hyper cloud transformation and cybersecurity professional services added to the portfolio.

In the past year, the business acquired several datacentre assets from fallen datacentre provider Sungard, in an effort to improve energy efficiency and be active in the energy market.

With the energy programme continuing, Redcentric expects the benefits to be fully reflected in its 2025 results for the first time.

The firm cited positive net new business after it invested in its organic growth.

In 2024 it will focus on integrating the recent acquisitions.
