Founding Story
In 2007, MIT graduate Drew Houston was on a bus from Boston to New York when he realised he had left his USB drive at home. He began writing file-sync code on the trip. Y Combinator required him to find a co-founder, and he teamed up with MIT student Arash Ferdowsi, who left school to join. A short demo video posted to Hacker News and Digg in 2008 pushed the beta waitlist from about 5,000 to roughly 75,000 people overnight, according to Houston.
Founders
Drew Houston
Drew Houston co-founded Dropbox in 2007 after forgetting his USB drive on a bus from Boston to New York and starting to write sync software during the ride. Y Combinator asked him to find a co-founder, and he partnered with Arash Ferdowsi. Houston served as CEO for 19 years, turning down an acquisition approach from Steve Jobs in 2009, taking the company public on Nasdaq in March 2018, moving it to a remote-first "Virtual First" model in 2020 and steering its push into AI with Dash. In May 2026 he named Ashraf Alkarmi co-CEO and said he would become executive chairman after a transition period. Houston holds Class B shares with 10 votes each, giving him significant voting control. Drew Houston was born in 1983 in Acton. Education: Massachusetts Institute of Technology; Acton-Boxborough Regional High School.
Arash Ferdowsi
Arash Ferdowsi met Drew Houston in 2007 and dropped out of MIT in his final semester to co-found Dropbox. As chief technology officer he helped build the early sync engine and engineering team. He later stepped back from day-to-day management and left Dropbox in 2020. Arash Ferdowsi was born in 1985 in Overland Park. Education: Massachusetts Institute of Technology; Blue Valley Northwest High School. Ferdowsi was born on October 7, 1985.
