Team

Will Headley

Head of Prediction, System1 Group

I graduated from Bristol University in 2000 with a Microbiology & Pathology Degree before joining Simon Godfrey Associates, part of Research International. Here I completed their graduate programme and MRS training, developing a passion for innovation, experimentation and validation. From 2003 I worked across the Kantar network, from a global innovation and advanced analytics role in the TNS Marketing Science Centre to UK Consumer Account Director and an exciting secondment in Mexico. I love working across a diverse range of markets and categories,although food and drink are particular personal favourites that I like to be experimental with at home too. I joined System1 Research in 2012 to validate, shape and create modern research methods that draw on the behavioural sciences. I have helped to develop our Fame, Feeling and Fluency brand tracking and applied System 1 forecasting enhancements to concept and ad testing, such as the application of response time data.
