Greg is the founder and CEO of Octopus Energy Group, the green energy tech pioneer based in the UK with over 3.1 million customers, further operations in 13 countries and over 23 million accounts licensed worldwide to its green technology platform, Kraken. Launched in 2016, the company’s mission is to bring cheaper, greener power to all. Octopus Energy is also a leading investor in solar and wind energy, managing a £3.4bn portfolio of renewable energy assets across Europe.

Greg's vision of using technology to disrupt the energy market has enabled Octopus Energy to create tariffs which unlock the power of the green grid - offering cheaper electricity when the sun is shining and the wind is blowing. Its technology platform Kraken also achieves dramatically lower cost to serve than rivals, so cheaper, green power is delivered hand in hand with unbeaten customer satisfaction levels. With its smart tariffs proving customer appetite for flexibility, Octopus is pioneering a global system change to enable a cheaper, faster transition to renewables.

In September 2021, Octopus Energy Group was valued at approximately $5 billion following a $600 million investment from Generation Investment Management and a $300 million investment from Canada Pensions Plan Investments Board. Both investors back businesses that drive sustainability, promote green energy and tackle climate change. It was the company’s third major investment round since launching to the market. With operations in the US, Japan, Germany, Spain, Italy, New Zealand and Australia, Octopus Energy Group's mission to drive the affordable green revolution is going global.

Greg is an experienced digital entrepreneur, passionate about using technology to make positive change. He’s founded a number of successful businesses, including e-commerce company C360, and is an angel investor in a wide range of tech start-ups. He also served as Director of several innovative businesses, including Zopa, the world’s first peer-to-peer lender, which has now lent almost £2bn fairly and responsibly.
