Better known as an ISP in its native Hull, KCOM also provides contact centre solutions to large enterprises and public sector customers via its Kcom Enterprise division. The fate of this Cisco and AWS partner is a little unclear, however, with a report from the FT in May suggesting that new KCOM owner Macquarie is looking to sell off non-core units. Slightly dusty accounts show Kcom Enterprise turned over £89.7m in its year to 31 March 2019.
