Lynch, 51, raised $1bn for his venture capital fund Invoke Capital – while being sued for £3.4bn. He sold his software company Autonomy to HP for £6.5bn but the tech giant took legal action, claiming he "engaged in fraudulent activities". Lynch countersued for more than £100m. A Cambridge graduate who grew up in London's East End, he had a stake in Autonomy worth £489m, but amid the legal uncertainty we value him at £469m.
