Octopus Energy

Greg Jackson and his wife Harriet Lamb launched Octopus Energy in August 2015 from London with a simple mission: to prove that renewable energy could be cheaper and more customer-friendly than the fossil fuel-heavy models dominating the market. The company grew rapidly by offering 100% renewable electricity plans and leveraging data to manage supply and demand more efficiently than traditional utilities. By late 2026, the brand had expanded its reach to serve approximately 14 million customer accounts across eight million households in the UK alone.

The business model relies heavily on technology rather than physical infrastructure. Through its Kraken Technologies division, Octopus provides software solutions that allow other global suppliers to run their operations digitally. This approach enabled the firm to expand into markets like France, Germany, Italy, Spain, Australia, Japan, New Zealand, and the United States without the heavy capital expenditure required by legacy power companies.

Recent strategic moves highlight a shift toward becoming an integrated energy platform. In September 2026, the company acquired Danish automated power trader BD Energy to strengthen its algorithmic trading capabilities in European markets. Earlier that same year, it secured a majority stake in Uplight to accelerate US expansion plans focused on grid flexibility and battery-enabled electricity services. [edit]
