72. Wavenet

Revenue: £60m (+14%)

Staff: 238

Having boosted its revenue runrate beyond £100m in November 2021 when it acquired Excell, Wavenet made another sizeable purchase in August 2022 in the form of IT support and cybersecurity outfit OGL. The headline number in this profile - which relates to the year to 30 April 2021 - consequently does no justice to the Mitel, Microsoft, Silver Peak and Cisco partner's enlarged scale. Wavenet has made four acquisitions since Macquarie Capital replaced Beech Tree as its private equity backer in May 2021.
