This software licensing behemoth became Europe's second-most valuable reseller behind only Bechtle this August upon its £2.2bn debut on the Swiss stock exchange. The Microsoft and Adobe partner's UK arm saw revenues rocket 27 per cent to £174.8m in its year to 31 December 2018, which it attributed partly to having a "stronger and more senior salesforce", while net profits bulked up from £2.3m to £3.4m. Recent acquisition Comparex outgrew it in the UK last year, however.
