Sunday Times Welsh Rich List: Wealth 'comes from internet'
Up to half the people on The Sunday Times' Welsh rich list made their fortunes through the internet or other forms of technology.
Cardiff-born Sir Michael Moritz - who has invested in Google and WhatsApp - is the wealthiest, worth £2.963bn
The Perkins family, owners of Specsavers, are second with £1.7bn, while Simon Nixon, Moneysupermarket.com co-founder, is third and has £1.25bn.
Robert Watts, who compiled the rich list, said many on it were self-made.
"Gone are the days when the rich list was dominated by the landed gentry and inherited wealth," he said.
"We're seeing a lot more self-made wealth created by entrepreneurs - often from modest backgrounds.
"Fortunes are still being made from traditional businesses like housebuilding, insurance and publishing, but it's striking how nearly half the names of our Wales list made their money through the internet or other forms of technology - often quickly amassing fortunes from businesses that were scarcely imaginable when we compiled our first rich list back in 1989."
The list - in its 30th year and published in The Sunday Times Magazine on Sunday - shows Wales has five billionaires.
Private equity billionaire Sir Michael, 63, who is a partner in the Silicon Valley firm Sequoia Capital, saw his fortune grow by £334m in the last year to again top the Welsh rich list.
The Perkins family - headed by Llanelli-born Douglas Perkins - increased their wealth by £100m this year to £1.7bn.
In third position was Simon Nixon, from Flintshire, who dropped out of university before later forming the internet giant Moneysupermarket.com.
His wealth increased by £74m this year, reaching £1.25bn, while Cardiff-born West Ham United co-owner David Sullivan's fortune remained unchanged at £1.1bn.
Celtic Manor owner Sir Terry Matthews, who is originally from Newport, was the only Welsh billionaire to lose money in the last year - his wealth fell by £95m to £1.075bn.
