The Cisco Gold partner's impressive revenue growth is tempered only slightly by the fact that there was one set of accounts posted in between last year's Top VARs figure (£46.2m) and this year's.

The Leatherhead-based MSP reported growth across all areas of the business in its 2023 accounts, including collaboration, cloud, security and managed services.

In particular, the growth was supported by 50 per cent infrastructure sales growth over the course of the year.

It added 56 strategic accounts over the course of the year, and aims to continue this progress this year.

It has leaned on strategic vendor relationships with Cisco and Microsoft.
