Octopus Energy entered the UK energy market in 2015 as a challenger brand, growing rapidly to serve millions of customers. Traditional energy suppliers relied on large, expensive customer service operations that delivered poor experiences — the industry consistently ranked among the lowest in UK customer satisfaction. Scaling customer service to handle complex billing enquiries, tariff changes, meter readings, and complaints while maintaining quality created a fundamental tension between growth and service standards.
The broader energy sector faced a technology deficit: most suppliers operated on legacy billing systems designed in the 1990s, making it difficult to launch innovative tariffs, integrate renewable energy sources, or respond to regulatory changes quickly. The transition to smart meters, time-of-use pricing, and distributed energy generation required technology platforms that incumbent systems could not support.
Octopus Energy built Kraken, a proprietary AI-powered energy technology platform that manages every aspect of the customer relationship — from billing and communications to smart-meter integration and energy trading. Kraken's AI tool, Magic Ink, uses GPT-style models to summarise customer histories and generate personalised responses, cutting service times while maintaining a personalised touch. The AI now handles the equivalent of 250 employees' worth of customer support — with customer emails answered by AI achieving an 80% satisfaction rate compared to 65% for human agents.
The platform automates up to 40% of digital communications and reduces cost-to-serve by 40%, enabling utilities to launch new tariffs and products in days rather than months. Beyond customer service, Kraken powers demand-flexibility programmes through Kraken Flex, where participants save an average of $340 annually on electricity while contributing to grid stability during peak demand events.
In September 2025, Octopus Energy spun off Kraken as a standalone business valued at $8.65 billion, with $500M in committed annual licensing revenue. Kraken is now contracted to serve over 70 million household and business accounts worldwide across multiple energy companies.
