Tech Track 100

Patrick Caiger-Smith, 56, and Simon Anderson, 67, started this Cambridge business in 2006 and have since sold more than 5m of their smart energy monitoring devices across the UK and Europe. Its products — which include smart thermostats and metering devices — are mostly sold to utility companies such as British Gas and EDF, and are designed to help customers save money on their home energy bills. The firm’s eco credentials have helped it receive backing from the Low Carbon Innovation Fund, while other investors include the former Dragons’ Den tycoon Nick Jenkins. Sales hit £29.4m in the year to March 2018 and it is developing a Hybrid Home system, which combines metering, solar, storage and appliance control to maximise energy efficiency.
