Our Vision

A habitable world for future generations through climate-driven decisions


Unravel's story

We started on this journey because we have only 6 years left to decelerate the impacts of climate change. But less than 10,000 companies of 400M companies globally are measuring their carbon emissions.

Unravel enables enterprises to decarbonize themselves and their large ecosystems of enterprises, with speed and scale.

Our Team

We are a team of software engineers, data scientists, founders and climate experts with a passion to solve the world's most pressing issue — climate change.
