Marketing systems that use the power of artificial intelligence to process enormous amounts of structured and unstructured data are beginning to reap significant benefits for marketers. I recently discussed the opportunities and challenges related to AI in marketing with David Steinberg, CEO and co-founder of Zeta Global. Steinberg's company has been partnering with marketers to tap massive amounts of data and link it to specific individuals in order to help marketers create personalized actions based on relevant insights. Here are the highlights of our discussion. John Ellett: Why did you start Zeta Global? David Steinberg: When my partner John Sculley and I started Zeta 10 years ago, it was all about unlocking data and turning it into actionable capabilities.
