Dropbox (NASDAQ: DBX) is an American cloud storage, file-sync, and collaboration company founded in 2007 by Drew Houston and Arash Ferdowsi out of MIT, headquartered in San Francisco, that pioneered the consumer "magic folder" model of automatic file synchronization across devices.
The company launched publicly through Y Combinator's summer 2007 batch and quickly became one of the canonical consumer SaaS success stories, scaling to hundreds of millions of users on a freemium model and going public on the NASDAQ in March 2018. Its product line has expanded well beyond raw file sync into Dropbox Paper, Dropbox Sign (formerly HelloSign), Dropbox Capture, Dropbox Replay, and a broad suite of integrations and admin tools aimed at distributed workforces and creative teams. Dropbox has continued to operate as an independent public company despite repeated speculation about acquisition by larger platform incumbents, and its founder-led leadership under Drew Houston has remained a recurring reference point for first-generation SaaS company culture.
