Decisions That Made Me: Greg Jackson (Octopus Energy)

Born in Halifax, West Yorkshire, Greg Jackson left school at 16 to write computer games, later joining Greenpeace before returning to study economics at Cambridge. Growing up in a family so stretched that the energy supply was cut off, he channelled that experience into a drive to make energy fairer and more affordable. By his twenties he was running a mirror business, before moving into tech start-up investing. In 2016 he founded Octopus Energy. Less than a decade on, it serves more than 7 million customers in 18 countries, manages a £6 billion renewable portfolio, and licenses its Kraken technology to utilities worldwide — with the company now valued at close to $9 billion.
