Drew Houston is the CEO and cofounder of Dropbox, and has led Dropbox's growth from a simple idea to a service relied upon by millions around the world.

Prior to starting Dropbox, Drew studied computer science at MIT, during which he also founded Accolade, an online SAT prep startup.

After graduating from MIT, Drew recognized that people needed a way to bring their files with them without sending email attachments or carrying USB drives. He began writing a solution to this problem in 2007, before demoing an early version to Arash Ferdowsi in Boston. The two of them then began working on the project that would eventually become Dropbox.
