It's an exciting start for the cybersecurity company, which had been dogged by the continuing allegations of fraud facing one of its key investors, Mike Lynch, who helped launch the company back in 2013. Lynch is facing extradition to the U.S. where he faces criminal charges relating to HP's $11 billion acquisition of his old company Autonomy. Lynch has denied all wrongdoing. Reports had also raised issues around Darktrace's hard-driving sales culture, while Forbes had previously reported on the abiding influence of Lynch and another former Darktrace director, Sushovan Hussain, who was convicted in the HP fraud case, though has been fighting an appeal. There were also allegations of sexual harassment within the startup.
