Nine months after reportedly putting itself up for sale, Birchbox appears to have found a buyer for a majority stake in its business. Viking Global Investors, a hedge fund and prior investor in Birchbox, has invested $15 million into the subscription box retailer, according to a report from Recode. If accurate, the price would undoubtedly be a massive disappointment for Birchbox, which has raised nearly $90 million in total funding since its launch in September 2010. The retailer had a valuation as high as $485 million after its $60 million Series B funding in April 2014, making it clear that the Birchbox brand has since fallen out of favor in the eyes of potential buyers.

This latest round of funding brings Drift’s total amount raised to $107 million. The company said the funding will be used to improve customer service and success teams, as well as expand its product beyond email and messaging and into voice and video.
