Staff: N/A

London-based NSC Global saw its revenue grow to £56m off the back of growing with its existing client base, expanding its global presence, improving quality of delivery, building its accounts, reliability, responsiveness and innovation.

The MSP cited client demand for multi-national coverage, combined with cost-cutting initiatives as a key growth driver for its most recent year.

After a monts-long stint with the company, industry veteran Alex Tatham left the business on friendly terms to return to his old home at Westcoast.
