Marc Lore's entrepreneurial ventures primarily include Quidsi and Jet.com. Quidsi, which he co-founded with Vinit Bharara, started with Diapers.com and expanded to other verticals like Soap.com and Wag.com. The success of Quidsi caught the attention of Amazon, leading to its acquisition in 2010. After Quidsi, Lore launched Jet.com in 2014, which aimed to provide a disruptive shopping experience by optimizing the supply chain and offering competitive pricing. Jet.com quickly gained traction, leading to its acquisition by Walmart in 2016. This acquisition marked one of the largest e-commerce acquisitions in history and demonstrated Lore's ability to create valuable companies.
