Dropbox

Dropbox makes money by charging users for extra space to store their files and photos safely online. They give people the ability to see their files on any device, anywhere. They won by being the simplest “magic folder” that just worked without any confusing setup. Their secret is that once your life’s photos and files are in their cloud, it’s much easier to keep paying them than to move everything elsewhere. They use Code Leverage to run a Freemium model distributed through the internet.
