🤯 75,000 sign-ups overnight. In 2007, Dropbox founder Drew Houston, then an MIT student, was on a bus from Boston to New York when he realized he had forgotten his USB flash drive, preventing him from working on important files. This personal frustration sparked the idea for a cloud-based storage service that would make files accessible from anywhere, on any device.

But instead of spending months building a complex, cross-platform product, Houston created a simple, narrated screencast video that demonstrated how the proposed service would work. This acted as his MVP, and Houston posted the video on Hacker News and other tech community forums.

The response? Explosive.

The waiting list jumped from 5,000 to 75,000 sign-ups overnight. This massive surge in sign-ups provided undeniable proof of market demand for such a solution.
