UK cyber security vendor Darktrace is now valued at $1.65 billion after raising $50 million in a Series E funding round.
The AI firm claimed to have seen its revenue increased 100 per cent year on year in July.
The extra cash will be used to fuel an international expansion which has seen it open offices in Los Angeles, Mexico City and Sao Paolo.
Darktrace claims to have increased its headcount by 60 percent over the last year, giving it an employee base of 750 staff.
This latest investment round was led by Vitruvian Partners and included existing investors KKR and 1011 Ventures.
