What do we do? Most consumer behavior is influenced by the opinions of people we know and trust – family, friends, and colleagues. While marketers have known this for quite a while, they are challenged to act on it. Pursway empowers consumer-facing organizations to scale their target audience by identifying like minded individuals with a strong social affinity to their brand. Using our solutions, leading global organizations in telecommunications, retail, and financial services extend their marketing reach to the friends of their audiences. How do we do it? Pursway has developed a proprietary database that maps relationships between more than 150 million North American consumers. Leveraging machine learning, anti-terrorism techniques, Pursway is able to analyze billions of pieces of data from thousands of open data sources and connect the dots. The technology platform accurately determines who is a real-life friend of whom while matching entities to create a human network in which real-life connections are identified. What’s unique about us? We have sufficient transactional evidence that friends really do buy what their friends buy. Since we have the unique ability to identify the best friends of your target audience, we can extend your marketing reach to target the best friends of your best audiences. Our audience scoring capabilities include the ability to target both high propensity buyers and the most influential customers in your base, both of which are proven techniques used by sophisticated direct marketers. Why are we doing it? We believe that targeting the friends of your best audiences is a smarter way to extend your marketing reach and better reflects real life social buying behavior. It has proven to be a more reliable way to get results than targeting via social media.
