This London-based IBM Platinum partner this October appointed industry veteran Simon Frisk as group chief executive to "spearhead continued growth". The acquisitive cloud and managed services provider - which has in recent years gobbled up Niu Solutions, APSU and Tectrade - had yet to file its 2019 numbers as we went to press. Its calendar 2018 accounts, which do little justice to its enlarged scale, show a £2.1m net profit on revenues of £44.8m.
