Building a Marketing Machine

Equip teams to confidently respond to events in the marketplace

Proving and improving the impact of marketing to protect and grow budgets



ProRelevant was founded in 2002 in Atlanta, Georgia by current President Guy Powell. The company was born out of the developing marketing analytics market, when a statistical model was the only method available to analyze marketing success.


Our team helped bring to market one of the first uses of artificial intelligence through our proprietary MarketSim technology.


ProRelevant worked with leading marketers around the world to model how consumers make purchase decisions in a comprehensive way. Our analyses take into account consumers’ short-term response to media, pricing and distribution, as well as the long-term emotional impact of brand health (awareness and purchase intent) and brand imagery (brand relevance) using our Brand Equity Machine and MarketSim models.  


ProRelevant’s method of developing a completely competitive model led to deep insights on how to trade off the impact of short-term and long-term media, how to optimize the launch of a new brand or product, and how to respond to competitive initiatives.


Since its founding, the company has become a leader in applying machine learning and artificial intelligence (AI) to critical business problems. More importantly, ProRelevant has helped make the analytics function a core element of marketing operations.


Read more about this in the book, Marketing Machine: The Secret History of the Future of Marketing (ROI), which describes how marketing can be transformed into a predictable, reliable, and accountable generator of sales to help the company meet and exceed corporate sales and profit targets with high certainty and low risk.  ProRelevant also offers marketing machine training for brands that need help building their marketing machine.
