Angel investor and founder of electronics, hardware and consumer goods design, manufacturing and distribution firm PCH, Liam Casey (54) has set down some roots in London recently, buying a house there last year.

But the Cork native still also flits between there, San Francisco and Shenzhen as well. The Cork-headquartered firm is unlimited, meaning its accounts aren’t public. At one stage, his 33pc stake in it was worth at least €150m, but that may have since changed. Casey appointed former Flex CEO Mike McNamara as PCH’s chairman last year, and it’s thought he took a stake in the business, attracted by recent renewed growth after the loss of a lucrative contract with Apple several years ago, when revenues would have been about $1bn a year.
