Emily Weiss

In 2010, she captured the attention of millions with her beauty blog, Into The Gloss, which gives an insider's view of the routine and careers of beauty and fashion's biggest names. In 2014, she capitalized on her blog's popularity to launch Glossier, which now offers 22 different beauty products. Weiss's brand has become a cult favorite among millennials — to say the least (the brand once had a 10,000-person waitlist for its brow gel.) But her rise to prominence in the beauty industry didn't happen overnight. In the seventh grade, the Connecticut native wrote a letter that was published in Vogue magazine about a fashion spread featuring model Trish Goff. As a teenager, she worked as a weekend babysitter for a neighbor who worked for Ralph Lauren. Weiss scored an internship at 15 years old that helped to jump-start the rest of her career. Her hard work caught the attention of senior design director Whitney Fairchild. Fairchild recommended Weiss to Amy Astley, who was editor-in-chief of Teen Vogue at the time. Astley was impressed with the young intern and brought her on board to work at the magazine. From there, Weiss held a number of assistant jobs at Condé Nast before making the decision to launch her blog in 2010. Today, Glossier is continuing to expand, and has plans for a retail space set to open later this year that will allow the company's customers to buy products both online and in-store.
