Sir Michael Moritz and Harriet Heyman
Rank 2017

Moritz recently likened fellow private equity billionaire Stephen Schwarzman to a character in Goodfellas, the Martin Scorsese mafia film, for his close relationship with Donald Trump. He had previously described the US president as “little more than a hustler who takes from the rich ... and also takes from the poor”. Cardiff-born Moritz, 62, is a partner in the Silicon Valley firm Sequoia Capital. He is the wealthiest person from Wales on our list.
   Sequoia was an early backer of Google and saw the value of its £8m investment in the search engine colossus soar to £6.3bn at its peak. Backing Apple, PayPal, Yahoo and WhatsApp has also paid off handsomely.
   A Manchester United fan, Moritz wrote a book on leadership with former manager Sir Alex Ferguson. Moritz and his wife, the American author Harriet Heyman, live in San Francisco. They recently donated $50m to the University of Chicago’s scholarship programme for low-income students, following a similar £75m gift to Oxford, where he studied history. Moritz was knighted in 2013 for his promotion of British economic interests and his philanthropy.
