Sir Michael Jonathan Moritz KBE (born 12 September 1954)[3] is a Welsh-born American billionaire venture capitalist, philanthropist, author, and former journalist.

Moritz works for Sequoia Capital, wrote the first history of Apple Inc., The Little Kingdom, and authored Going for Broke: Lee Iacocca's Battle to Save Chrysler.

[9] Moritz earned a bachelor's degree in history at Christ Church, Oxford, and in 1978, an MBA from the Wharton School of the University of Pennsylvania as a Thouron scholar.

[12] According to Andy Hertzfeld, in response to the fact that a history of another computer company had been published a year earlier, Jobs said: "Mike's going to be our historian."

His research included a lengthy interview with Jobs' high school girlfriend, Chrisann Brennan, in which she discussed the history of their child, Lisa.

[17] In the prologue to Return to the Little Kingdom, Moritz states that he was as incensed as Jobs was about the Time Magazine special issue: Steve rightly took umbrage over his portrayal and what he saw as a grotesque betrayal of confidences, while I was equally distraught by the way in which material I had arduously gathered for a book about Apple was siphoned, filtered, and poisoned with a gossipy benzene by an editor in New York whose regular task was to chronicle the wayward world of rock-and-roll music.

Steve made no secret of his anger and left a torrent of messages on the answering machine I kept in my converted earthquake cottage at the foot of San Francisco’s Potrero Hill.

I finished my leave [and] published my book, The Little Kingdom: The Private Story of Apple Computer, which I felt, unlike the unfortunate magazine article, presented a balanced portrait of the young Steve Jobs.

[19] In 1986, Moritz joined Sequoia Capital after co-authoring Going for Broke: The Chrysler Story with Barrett Seaman, Time's Detroit bureau chief.

[20] He currently sits on the boards of 24/7 Customer, Earth Networks, Gamefly, HealthCentral, Green Dot Corporation, Klarna, Kayak.com, LinkedIn, Stripe and PopSugar.

[21] Google was one of several co-investments with John Doerr of rival venture capital firm Kleiner Perkins Caufield & Byers,[22] and the initial public offering of the company in 2004 made Moritz one of Wales' richest men.

[36][37][38] In July 2010, Moritz was awarded an honorary fellowship from Cardiff University,[39] where his father Alfred had previously been Vice-Principal and Professor of Classics.

[10][23] In May 2012, Moritz announced that he had been diagnosed with a rare, incurable medical condition and would step back from his day-to-day responsibilities at Sequoia Capital while also being elevated to the position of chairman.

[52] In October 2016, The Guardian reported that Michael Moritz "donated $49,999 to a divisive ballot measure intended to clear San Francisco’s streets of homeless encampments, according to campaign filings".
