This Bowmark Capital-backed telecoms, IT, data and energy provider has seen its headcount swell to 800 employees following a frenetic M&A drive (which included four acquisitions in 2022). Revenues hit £115.7m in its year to 30 November 2021 - a 45 per cent pro-rated rise - as its acquisitions of swcomms and three other deals tied up during the period bolstered its top line. The West Sussex-based Mitel, Cisco and Avaya partner vowed in its strategic report to continue making acquisition in the unified comms space.
