Poppy Gustafsson, the co-founder and chief executive of the British cybersecurity firm Darktrace, is to leave the company after its $5.3bn (£4.2bn) sale to the US private equity business Thoma Bravo.
Gustafsson, one of the best-known figures in the UK tech industry, founded Darktrace in Cambridge in 2013 with backing from the late billionaire Mike Lynch’s Invoke Capital.
