Revenue: £113.9m (+22%)

This acquisitive Microsoft partner's enlarged scale is done no justice by the headline figure in this profile, which is based on dusty old calendar 2020 accounts (2021 accounts were overdue as the report went to press). Nasstar claimed in November that it is now a £200m-revenue business, as it unveiled former New Signature UK boss Paul Cosgrave as its new CEO. This follows quickfire acquisitions of Nasstar plc, Smart421, Modality and KCOM's ICT business. In April 2022, the Mayfair Equity Partners-backed outfit began work on a "major" contract to kit out 59 MoD sites with a Fortinet SD-WAN and NAC solution.
