Marc Lore sold Diapers.com and his others sites to Amazon and worked for them for a couple years.

He then left Amazon and founded Jet.com. He ran Jet for a little bit and then sold it to Walmart. Walmart put him in charge of their US e-commerce sales, and they shut Jet down and pointed the domain to Walmart.com.

He left Walmart in recent years and I’m not sure what he’s up to currently.
