Dropbox (2007) = Pioneered… Consumer-Grade Product With Enterprise Appeal… Dropbox synchronizes files across your / your team's computers…files are securely backed up to Amazon S3. It takes concepts that are proven winners from the dev community & puts them in a package that my little sister can figure out… Competing products force the user to constantly think & do things… With Dropbox, you hit "Save," as you normally would & everything just works. - Drew Houston, Founder, Y Combinator Application, Summer 2007 264
