Walmart has added Kevin Systrom, the co-founder and CEO of photo-sharing service Instagram, to its board. The retail giant, based in Bentonville, Ark., said it picked the 30-year-old for his tech and entrepreneurial background. “Kevin’s entrepreneurial background and his technical and digital expertise will be invaluable as we further connect with customers and deploy new capabilities through e-commerce and mobile channels,” said Walmart Chairman Rob Walton, in a release. Systrom, who sold Instagram to Facebook in 2012 for $1 billion, will serve on the company’s Technology and eCommerce Committee and its Compensation, Nominating and Governance Committee. Another tech veteran on the company’s board is Yahoo CEO Marissa Mayer.
