Emily Weiss is an American entrepreneur renowned for founding Glossier, a direct-to-consumer beauty brand established in 2014. Glossier emerged from her beauty blog, Into the Gloss, and quickly gained a dedicated following for its minimalist aesthetic and community-driven product development. Under Weiss's leadership, Glossier achieved a valuation exceeding $1 billion, revolutionizing the beauty industry by prioritizing customer engagement and leveraging social media for growth. In May 2022, Weiss transitioned from her role as CEO to Executive Chairwoman to focus on motherhood and strategic aspects of the company.

During her studies at New York University, Emily Weiss interned at Teen Vogue, gaining early exposure to the fashion and beauty industries. After graduating in 2007, she worked as a fashion assistant at W magazine and later as an on-set styling assistant at Vogue, collaborating with stylist Elissa Santisi. These experiences provided Weiss with a deep understanding of the beauty market and its consumers, laying the groundwork for her future entrepreneurial ventures.

In 2010, Emily Weiss launched Into the Gloss, a beauty blog that featured interviews with influential women discussing their beauty routines. The blog's success highlighted a gap in the market for beauty products that resonated with a modern, engaged audience. Leveraging this insight, Weiss founded Glossier in 2014, introducing a line of beauty products developed in collaboration with the brand's community. By harnessing the power of social media and fostering direct relationships with consumers, Glossier rapidly expanded its product offerings and customer base, securing substantial venture capital funding and achieving unicorn status within five years.
