After departing Walmart at the end of January, the serial entrepreneur has joined his brother, Chad Lore, to invest in Wonder, a business that is part food truck, part ghost kitchen, CNBC has learned. Scott Hilton, a longtime colleague of Marc Lore's and former chief revenue officer of Walmart's e-commerce business, is Wonder's chief executive, a person familiar with the investment said. Chad Lore also holds a top role, while Marc is serving in an advisory capacity, said the person, who requested anonymity since the business is still in an early stage. Marc Lore, 49, is most known for creating innovative e-commerce businesses and selling them to corporate giants like Amazon and Walmart.
