Octopus Energy

Octopus Energy is a global green energy company and the largest domestic energy supplier in the United Kingdom. It provides renewable electricity and gas to more than 10 million homes across 18 countries on four continents, and licenses its technology platform to other utilities. The company has raised over $1.5 billion in funding.

At the centre of its operations is Kraken, a proprietary technology platform used to manage energy retail operations and customer accounts. The platform supports 54 million customer accounts globally and is licensed to major utilities outside the Octopus Energy group. Technical work spans the Kraken platform itself, renewable energy generation management, smart grid and energy retail systems, and customer service automation.

Beyond software, the company manages a £6 billion renewable energy portfolio of more than 400 green generators, including wind and solar farms. During the energy crisis it absorbed over £150 million to keep its UK variable tariff at the lowest rate. Its customer-facing record includes a 5/5 Trustpilot rating from more than 760,000 reviews and a Which? recommendation for nine consecutive years.

Industry verticals include energy retail, renewable energy and utilities technology, with a stated focus on affordable, green energy and a mission-driven approach to the energy transition.
