Despite Covid making for an "extremely challenging" second quarter, this Staffordshire-based public sector reseller and system builder grew by a quarter in calendar 2020. As well as selling its own-brand PCs and devices and solutions from the likes of Cisco Meraki, Acer, Lenovo and Microsoft, Souter Investments-backed Stone doubles up as an IT asset disposal firm, and in October 2020 launched a "game changing" app - Stone 360 - designed to help customers organise equipment takeback.
The first national lockdown prevented Stone's ITAD and engineering services from operating, leading it to lean on the government's furlough scheme to the tune of £772,000 during the year. But trading returned to "record levels" by Q4 "as the country came to terms with how to live with the virus", Stone said.
