Dropbox

Overview

Dropbox was founded in May 2007 by MIT students Drew Houston and Arash Ferdowsi. Houston has said he was inspired to build the service after repeatedly forgetting a USB flash drive while traveling between Boston and New York. The company was initially incorporated as Evenflow, Inc. and received seed funding from Y Combinator before rebranding to Dropbox, Inc. in October 2009. Dropbox is headquartered in San Francisco, California, and went public on March 23, 2018, listing on the Nasdaq exchange under the ticker symbol DBX.

Dropbox works by synchronizing a designated local folder on a user’s device with files stored on Dropbox’s servers, so that changes made in one location propagate automatically to all linked devices and to the web interface. The service later expanded beyond simple file sync to include shared folders, file-request links, a collaborative document editor called Dropbox Paper (launched in January 2017), and Smart Sync, which lets users see and open cloud-stored files without keeping a full local copy. Dropbox offers free and paid subscription tiers, with paid plans (marketed under names such as Plus, Essentials, Business, and Business Plus) providing increased storage, extended version history, and administrative controls for teams.

• Dropbox Paper — Collaborative document editor for real-time team writing and planning
• Smart Sync — Access to cloud-stored files without downloading a full local copy
• Version history — Recovery of deleted or overwritten files, with a default 30-day window extendable on paid plans

Who It’s For

Dropbox is aimed at individuals, small teams, and businesses that need a straightforward way to store files in the cloud and keep them synchronized across multiple devices. It is distributed as a freemium service, with a free tier offering limited storage and paid subscription plans for individuals, teams, and enterprises requiring more storage and administrative features.
