System1Group’s drive to discover breakthrough marketing solutions guaranteed to help their clients grow more (and waste less) has led to them being voted the “Most Innovative Agency” by clients and agencies alike for six of the past seven years:

  • System1Group have been the first to champion the predictive accuracy, cost & speed advantages of online research.
  • They’re also the first to use online’s interactive and recursive capability, to automatically capture and structure any number of open-ended consumer responses. Since 2000, System1’s MindReader has been used 50m times collecting over 100m open responses.
  • They are the first to champion the accuracy of Predictive Markets (wisdom of crowds) and validate its ability to better predict the market potential of our clients’ new product ideas. Since 2004 we have successfully assessed the market potential of over 50,000 innovations.
  • Finally, System1Group are the first to create an online measure of emotion and validate that a consumers’ feelings about a brand and its marketing are the best predictor of their market potential.

System1 is an ambitious business. Their objective is to continue to spearhead our industry’s change agenda. This innovative and entrepreneurial spirit has led to more major new global launches for this year that will change the way Marketing Leaders approach Market Research:

  • The first to launch a service that will test every single Ad that runs on Television in the UK and USA. System1 Ad Ratings will be online and subscription based and will provide predictive next day ratings for any new ad – and past 12 months advertising performance – for any brand or company. We are predicting this will become the industry standard – and a “must have” tool for every marketing leader in the world.
  • The first to launch a better, cheaper faster way for clients to test earlier, more often, more accurately than ever before. The System1 Creative Guidance System is a new Research & Strategic Guidance tool that has been specifically designed to be flexible enough to fit with any client’s existing advertising development process.
