About Entropy

About Entropy

We built the kind of measurement and marketing consultancy we wanted when we were client-side.

Entropy combines specialist measurement expertise with senior marketers who have been responsible for the decisions that measurement is supposed to inform. That changes how we work: we start with the decision, make complex evidence understandable, and stay focused on what the organisation needs to do differently as a result.

Entropy MMM

We bring client-side marketing expertise, radical transparency, and a challenger mindset to MMM – powering faster, sharper P&L decisions.

We continually innovate to solve modern measurement challenges for our clients and the industry. Some recent examples include:

Developing best practice for OOH to be measured in MMM with the trade bodies ISBA and Outsmart


Similar work we’ve done for radio and influencer media.


A faster, cheaper approach to MMM we call Dynamic Marketing Mix Modelling (DMMM) suited to “scale up” brands.


Recently we’ve also been rapidly developing our approach to Amazon MMM to help clients optimise the largest source of retail media spend globally.
