Dropbox

Dropbox is the company that made 'just put it in my Dropbox' a sentence everyone understood. Founded in 2007 after Drew Houston got tired of forgetting his USB drive, it turned file sync into a verb and grew into a content-collaboration platform used by roughly 700 million registered users and about 18 million paying subscribers. Today the San Francisco company, public on the Nasdaq as DBX with about $2.5 billion in annual revenue, is betting its next chapter on Dash, an AI-powered universal search layer that hunts across every app where your work actually lives.
