Revenue: £45.3m (+85%)

Staff: 392

This LDC-backed buy-and-build now has a £60m revenue runrate and 600 staff, it claimed last July when it announced its latest acquisition (that of TDS Global Holdings' comms and compliance practice). In its first full reporting year, ending 31 March 2022, the Microsoft, Genesys and Citrix partner notched up an adjusted EBITDA of £7m on revenues of £45.3m. Those numbers were bolstered by its acquisitions of cloudThing and Gyrocom in May and October 2021.
