36 Claranet UK

Revenue: £115.5m (-1%)

Net profit: 4.8% Staff: 506

Starting life in 1996 as an ISP, today this London-based, globe-trotting MSP turns over £440m and claims to be one of just five partners globally to hold MSP badges with AWS, Azure and Google Cloud. It also partners with VMware, Cisco and Nutanix. Claranet's UK arm saw revenues roll back one per cent to £115.5m in its year to 30 June 2020, "mainly due to the impact of Covid in the last quarter". The Tikehau Capital-backed firm, which has 2,500 staff and 10,000 customers, has acquired in Germany, Spain, Portugal and Brazil in 2021.

Covid impact

The pandemic has had a "minimal impact" on revenues overall, Claranet said. Although some customers put decisions on hold, others working in critical industries turned to the MSP to rapidly scale services, it explained.
