As a long-time financial services marketer, you would expect Dan Marks to have the science of marketing down pat. And indeed he does, having built a predictive marketing spend model at First Tennessee Bank (see my book The CMO's Periodic Table: A Renegade's Guide to Marketing!) and the marketing tech infrastructure in his current role. But Marks sees the trend towards data-driven marketing going too far, explaining that, "Just doing the science without starting with the purpose is a recipe for failure." Embracing the art-side of his job, he encourages his team to "remember that we are ultimately serving people" and to look at what's happening with people in other categories."

Dan Marks is the CMO for Hancock And Whitney Bank, a regional bank in the Gulf South spanning from Houston, Texas, to Tampa, Fla. At the bank, Marks is responsible for overall strategy and execution of marketing and leading a digitally enabled client-focused transformation. Recognitions have included the Presidents Circle CMO Award, "Top CMO on Twitter," and "Top 40 under 40."
