Revenue: £162m (+57%)
Headcount: 930
Having built a substantial Microsoft business via a trio of acquisitions in 2021 and 2022, this Derby-based co-location and private cloud provider saw revenues power up 57% to £162m in its year to 31 March 2023. It claims it exited the period with a “strong” order book. The Providence Equity-backed outfit, which sells to the midmarket and via the channel, made only one purchase in 2023 in the form of security and technology risk specialist ThreeTwoFour.
Oxygen ice-breaker: In August 2023, Node4’s recently acquired risual business bagged a £74m, two-year digital services contract with Defra (in partnership with Atos-owned Eviden).
