RedstoneConnect holds the distinction of being the only firm in this report that no longer exists. The AIM-listed outfit rebranded as SmartSpace Software in July 2018 following the sale of its managed services and systems integration activities to Excel IT in May. It now focuses solely on developing its own occupancy management software, an activity that generated just £5.3m of its £47.6m revenues in its year ending 31 January 2018.
