Octopus Energy, a privately owned company headquartered in the UK, was founded in 2015. With an estimated 5,010 employees, the company operates across Europe, North America, Asia, and Australasia. It functions as an integrated energy technology developer and utility supplier, serving as the United Kingdom's largest domestic energy supplier by managing 14 million customer accounts across 8 million households. Its operations encompass multiple distinct units, including Octopus Energy Retail, Octopus Energy Generation, Octopus Energy Services, and Octopus Electric Vehicles, which collectively coordinate renewable asset management, heat pump manufacturing, and smart vehicle leasing. The company's operational foundation relies on its proprietary, AI-driven cloud software platform, Kraken Technologies. This platform is licensed to international utility conglomerates such as EDF, E.ON, and Origin Energy, where it dynamically automates localized smart-grid distribution, processes advanced time-of-use and variable customer tariffs, and manages over 50 million contracted consumer accounts worldwide to drive the systemic electrification of transport and heating infrastructure.
