The deal, backed by private equity firm Vespa Capital, will see West and the management team acquire the shareholdings from the company’s co-founders, chief executive Andrew Mabbutt and chief strategy officer Matt Eames, along with those of chairman Nicholas Wheeler and the minority shareholders.

West becomes chief executive, with the rest of the management team comprising chief finance officer Richard Sawney; technical director Paul Greatbatch; Steph Heasman, director of customer success; and James Winn, US vice-president of sales and operations.

West said: “This new investment will fuel our programme of enterprise-level expansion, while enabling further innovation within our market-leading data analytics and artificial intelligence capabilities. The continued evolution of our technology as a comprehensive customer experience management platform is enabling brands to make smarter business decisions every day.”

The agreement was completed on 15 November with the co-founders and existing shareholders being advised by Stella EOC. The management team, led by West, were advised by Livingstone.
