Marc Lore was President and CEO of Walmart eCommerce U.S. from 2016-2021. Under Lore, Walmart expanded its online merchandise catalog eightfold, while giving small merchants selling on Amazon another marketplace option to try to diversify their businesses. Walmart also introduced free two-day shipping, as well as next-day and same-day delivery options on a limited selection of goods.

Prior to Walmart, Lore worked in the finance industry, at Banker's Trust, Credit Suisse First Boston, and Sanwa Bank, then embarked on entrepreneurial ventures. Lore founded companies including Diapers dot com, Jet dot com, and The Pit, Inc.

In 2005, he and Vinit Bharara founded 1800DIAPERS, which would be rebranded as Diapers dot com and fall under the parent corporation Quidsi, Inc. According to a 2009 interview, his vision for Diapers was inspired by his own family's experience with the difficulty of keeping necessary baby-care goods in stock.

From 2005 to 2012 the company launched a portfolio of websites catering to families, including Soap dot com and Wag dot com. Lore and Bharara were successful in building a loyal customer base among young parents in urban areas. To improve the economics of shipping bulky, low-margin products like diapers to their customers, they established warehouses relatively close to urban areas to take advantage of ground shipping rates, instituted algorithms to minimize ship cost, and conducted warehouse operations using Kiva robots. The company was sold to Amazon in 2011 for $545 million.

Lore left Walmart in January 2021, with plans to spend more time on philanthropy, advising startups, and serving on public company boards, while also writing a book and working on developing a TV show.
