Why Octopus Energy sold its AI advantage to its own competitors

Why Octopus Energy’s generative AI tools worked better than most competitors’ attempts, and the multi-year infrastructure decision that made it possible

The specific difference between an AI copilot (human drafts, AI assists) and an autonomous AI agent (AI acts, human can intervene), and why Octopus deployed them in that order

How to evaluate whether an internal tool your team built for yourselves could become a product you sell to others, including direct competitors

A 7-day exercise for auditing your own internal AI tooling for hidden product potential

Octopus Energy, a UK energy retailer founded in 2015, built its own cloud-native operating platform, Kraken, from day one instead of buying legacy utility softwareOctopus Energy was officially founded in August 2015 by Greg Jackson, James Eddison, and Chris Hulatt, a tech entrepreneur frustrated by the UK energy market’s legacy systems and poor customer service who partnered with backing to build an energy company that acts like a tech company.

Once generative AI became viable, Octopus layered AI drafting and response tools directly onto that unified data platform. Its CEO reported the tools were doing work equivalent to about 250 customer support employees, with an 80% customer satisfaction score against 65% for trained human agents.

Rather than keep the platform internal, Octopus licensed it to other utilities, including direct competitors, and by late 2025 Kraken was contracted to manage over 70 million accounts across 27 countries.

In December 2025, Kraken spun out as a standalone company backed by a $1 billion funding round from Ontario Teachers’ Pension Plan, Fidelity International, and Durable Capital Partners.

The mechanism worth studying isn’t the AI. It’s the sequencing and the willingness to sell the tool to the people it was originally built to beat.
