Houston founded Evenflow, Inc. in May 2007 as the company behind Dropbox, and shortly thereafter secured seed funding from Y Combinator. Dropbox was officially launched at 2008's TechCrunch Disrupt, an annual technology conference. Owing to trademark disputes between Domains by Proxy, Inc. and Evenflow, Dropbox's official domain name was " getdropbox.com" until October 2009, when it acquired its current domain, "dropbox.com". In October 2009, Evenflow, Inc. was renamed Dropbox, Inc.
In an interview with TechCrunch's "Founder Stories" in October 2011, Houston explained that a demo video was released during Dropbox's early days, with one viewer being Arash Ferdowsi.
