About

James Harris

James’ background began in replenishment at Walmart in 1999. This gave him the opportunity to learn a great deal about not only how Walmart operates, but also how great companies manage their business at Walmart, as well as the mistakes that other vendors make when working with a massive retailer like Walmart. This planted the seeds of the idea for High Impact.

After Walmart, James spent nine years with CPG brands, mostly at Unilever Foods on the Walmart team, followed by two years on the Target team. Additionally, he spent two years as the Director of Mass Sales for Sleep Innovations, which gave him exposure to many other retailers, including Sam’s Club, Kohl’s, Amazon, and of course, Walmart and Target. 

James started High Impact in 2007 with the vision to partner with emerging and mid-tier brands doing business at Walmart, to operate as an extension of their own teams and execute with excellence at Walmart and beyond.

James lives in Rogers, Arkansas, with his wife Amy and their three children Ellie, Drew, and TJ. In his free time, he enjoys water sports with his family, music, theater, basketball, and trying his best not to kill the plants in his garden.
