From my understanding, the Jet.com deal was more of an acquihire to get Marc Lore to work for walmart.com[1]. The Jet.com numbers didn't look good at all, and they were rapidly burning through capital. Walmart didn't have technology as a core competency (nothing wrong with that), so it saw an opportunity to grow into the digital space through this acquisition. This leads me to think that everyone from the company is likely in golden cuffs.
