About Rio

We are a British headquartered, international sustainability technology company.

Rio is an intelligent, accessible sustainability  software platform that helps businesses and individuals become more  sustainable through data analysis, learning, and governance. 

Our proprietary AI analyses your data and provides transparent,  actionable recommendations for improving environmental impact, managing sustainability risk, and saving money on waste, energy, water, and more. 

We take knowledge from the sustainability sector’s leading minds and put it into the hands of everyday people and organisations — so we can  all do better together.

The Rio history

Late 1990’s

The company was originally founded based on pioneering AI research and was subsequently awarded a patent for ‘Knowledge acquisition” in expert systems.


We led a fundraising round of £4m to create our SaaS greenhouse gas accounting solution, supporting businesses with their carbon footprint reporting.

From 2020

The surge in demand for sustainability performance information, driven by investors and regulators, led us to expand into financial services, raise a further £1m and appoint Daniel Botterill as CEO.

In 2024

Our customers use thousands of ready to go sustainability KPI’s because we believe sustainability management is based on materiality specific to an industry, maturity, and organisational ambition.

The Rio Consultant Group and Rio-bot are what make The Rio Way unique.
