Sir Robin Keith Saxby (born 4 February 1947)[2] is an English engineer who was chief executive and then chairman of ARM Holdings, which he built to become a dominant supplier of embedded systems.

When he was appointed CEO in 1991, he took 12 engineers from Acorn Computers into the newly formed joint venture between Acorn and Apple Inc. With a limited budget of a $1.5 million investment from Apple, he made those 12 engineers into one of the most formidable management teams in the industry.

Saxby also introduced the licensing model for selling microprocessors, which led to a 95% market share in the mobile phone sector.

[1] During his 10 years as CEO, he made ARM the most valuable company in the Cambridge cluster, with a market capitalisation of over $10bn.

[1] Since his retirement from ARM, he has become a tireless promoter of young entrepreneurs and is involved in a number of start-up companies which he supports with advice, finance and infinite patience.
