B. What We Do

Powerfull is building an agentic AI platform that automatically optimises home batteries and energy trading — starting with Tesla Powerwall owners on the Agile Octopus tariff. Our platform helps households cut energy bills and increase earnings from stored energy by making intelligent, real-time optimisation and trading decisions on their behalf.

For the purposes of UK data protection laws, Powerfull acts as a Data Controller when determining how and why personal data is processed. In some cases, we may also act as a Data Processor when handling data on behalf of partners or project sponsors.
