6 World Wide Technology

Revenue: £611m (0%)

Net profit: NA Staff: 160

This 7,000-strong global IT solutions provider employs around 160 staff at its London base near Moorgate and claims to be a "go-to technology integrator for large institutions in the region".

A $13.4bn-revenue powerhouse globally, WWT does not file any UK accounts, making the headline number in this profile pure guesswork (although in the dim and distant past insiders assured us UK/EMEA revenues top £500m).

In a recent interview with CRN US, CEO Jim Kavanaugh revealed that the St Louis-based outfit has onboarded 1,000 net new staff in 2021, and plans to repeat the feat in 2022. In a break from tradition, it may also consider acquiring some "boutique" companies next year, he added. WWT was last month named Americas Partner of the Year at the Cisco Partner Summit Global awards.
