Pinterest is making a big move as it pushes further into online shopping. The image-focused social media site is acquiring A.I.-powered shopping platform THE YES as it focuses on enhancing the user shopping experience. THE YES's technology gives users a personalized feed of products based on their preferences, and Pinterest is banking on the tech to give it an advantage among other social media apps with built-in shopping features. Julie Bornstein, founder and CEO of THE YES, joins Closing Bell to discuss the company's unique technology, why it agreed to sell to Pinterest, her vision as she takes over shopping initiatives, and more.
