On June 28, Walmart is inviting more than 500 businesses from across the U.S. to pitch their Made in the U.S.A. products at its Bentonville, AR, headquarters, providing entrepreneurs the opportunity to potentially reach the retailer’s consumers in-store and online.

Now in its fourth year, Walmart’s Open Call is an investment in promoting American jobs by accelerating the growth of U.S. manufacturing. In addition to showcasing entrepreneurship, this year’s Open Call is said to focus on ingenuity and diversity. For example, a quarter of the businesses that will participate in the event this year identify themselves as women-owned.
