WHAT WE ALREADY KNOW ABOUT THIS INTERVIEW
Octopus Energy describes itself as an energy and technology group working across the post-transition energy value chain. Its Kraken platform supports customer management, billing, energy flexibility, smart devices, and utility operations.
The business is scaling quickly. Octopus Energy’s customer base grew from 5.3 million to 6.1 million during FY25, while Kraken revenue doubled year over year to £422 million.
Kraken reports more than 150 small production changes per day across client instances, with rollback capability. That makes safe delivery, observability, and practical technical judgment especially relevant topics to prepare for.
Every one of these came from something we read about Octopus Energy. The sources are linked, so you can check them.
