Our team combines the two disciplines that make our solution unique: “rocket science” algorithms and analytics, combined with down-to-earth yet forward-thinking marketing expertise.
Two of Pursway’s co-founders come from a highly analytical data mining background; the third co-founder brings the marketing and CRM know-how. Together, they created a solution that is a technological breakthrough, yet grounded in the reality that drives the marketing organization towards bottom line-results.
