Hayley Barna is an American entrepreneur and venture capitalist who co-founded Birchbox in 2009 while at Harvard Business School. In 2015, Barna "stepped away from her day-to-day role" at Birchbox, but remains as one of their board members. With Birchbox on her resume, Barna joined First Round, a venture capital firm specializing in seed-stage funding, as their first female partner.
Barna began her career shortly after she graduated from Harvard University joining Bain & Company in New York. She moved to Christie's Hong Kong location where she worked in strategy and then in product management for Amazon.com.
While working towards her MBA at Harvard Business School, Barna met Katia Beauchamp and a friendship was born. So, too, was the idea of Birchbox which Barna founded with Beauchamp. What began as a business plan during B-School turned into a website where they began to acquire customers interested in "an ecommerce experience focused on new product discovery." As of 2015, Birchbox had received over $70 million in venture funding and had one million subscribers. Barna stepped down from her role as co-ceo of Birchbox in 2016, but remained a member of the board.
On February 16, 2016, Barna shared a post on publishing platform medium.com about her first day at First Round stating, "I can’t think of a better place to do this than , which led the seed round in my company Birchbox, and has always put founders first through good times and bad."
During her time at Harvard Business School, Barna met her husband, Fredrik Vik Maroe. They wed in 2014 at a private estate located in Staatsburg, New York.
