Birchbox is a New York City-based online monthly subscription service that sends its subscribers a box of four to five selected samples of makeup or other beauty-related products.

[2] Birchbox was established in September 2010[3] by Katia Beauchamp and Hayley Barna, both graduates of Harvard Business School.

[9] In 2015, Barna stepped down from the co-CEO role at the company and joined the First Round Capital firm as a venture partner.

Five months after raising $90 million, it had a minority stake acquired in October 2018 by Walgreens, whose stores began offering its service.

[13][14] After being purchased by start-up FemTec for $45 million in October 2021,[15] the online subscription service was acquired in 2023 by Retention Brands.
