What We Do

ONZO combines the science of energy analytics with load disaggregation, energy lifestyle behaviour analysis and probabilistic forecasting to give utilities and their customers unprecedented insights into how, where and when energy is used. Leveraging granular smart meter data, ONZO’s patented algorithms result in richer, highly accurate, customer-specific insights that help utilities improve customer engagement and energy efficiency, while reducing churn and creating new revenue opportunities.

The company is headquartered in London, UK, with an office in the US, and works with clients all over the world.

Our Diversity

Diversity is crucial to the success of ONZO. We pride ourselves in sharing experience and cultures from all walks of life and fusing this experience into our approach, product and customers.


Telecoms, Research, Marketing & Advertising, Manufacturing & ERP, IT & Software Consultancy, Energy, SaaS and E-commerce experiences have all contributed to our product design.


Whilst our staff are diverse in professional background, they are equally diverse in origin and culture. Originating from the UK and Europe, Asia and the Americas, we’ve engendered an international culture within ONZO to help us to develop strong relationships with our customers around the world.


Through the promotion of close collaboration, we ensure that our design and user experience is core to every architectural and technical build. We have regular cross team workshops to help understand how we can all contribute to deliver the best experience we can.
