Mike Lynch obituary

British tech entrepreneur who sold his Autonomy software group to Hewlett-Packard and was later cleared after a long-running US fraud case

Mike Lynch, who has died aged 59 in the wreck of his yacht, was sometimes described as Britain's Bill Gates". It was a huge exaggeration, but Lynch could claim two parallels with Gates: he developed world-leading technology (in his case in machinelearning or AI) and, unlike so many UK scientists, he learned how to turn it into commercial success.

Such was this success that his company, Autonomy, was valued at $11bn when he sold it to Hewlett-Packard in 2011, but the fall-out from the sale would come to overshadow his technological achievements, and lead to a national debate about the circumstances in which UK citizens may be extradited to the US.
