MarTech is evolving rapidly, trouble is, marketers may not be keeping pace with tech advancements. According to Walker Sands' 2018 Marketing Technology report, more than two-thirds of marketers don't think there's such a thing as the "perfect stack" for marketing technology, believing instead that it's always a work in progress. The survey, conducted among 300 marketers in Q1 from companies of various sizes, found that the majority feel that the marketing technology landscape has evolved rapidly (48%) or at light speed (15%) over the past 3 years.
