Dropbox

Dropbox stores files in the cloud and keeps them in sync across computers and phones, so a team works on the same folders wherever it is. Files and folders are shared by link with access controls, version history and recovery. Around storage, the company sells several separate products: Dropbox Sign for legally binding e-signatures, DocSend for sharing documents with viewer analytics and data rooms, Dropbox Replay for frame-accurate feedback on video, image and audio, Dropbox Dash for searching across a company's work apps, and Dropbox Fax. Dropbox is used by freelancers, creative teams and small and mid-sized businesses, as well as by individuals for personal storage.
