This Nottingham-based business has helped energy suppliers support their customers through the pandemic by facilitating payment holidays and bolstering service levels. Its software platform enables companies, such as Centrica and Ovo Energy, to improve their customers’ experience, for example by providing quotes and managing billing and payments online. It was founded in 2010, and co-founder and chief executive Jon Slade, 41, led a management buyout backed by LDC for £15m in 2017. As part of the deal, Ian Peters, 61, former managing director of British Gas, joined as chairman. Sales this year hit £12.4m.
