Congratulations to our inaugural GO PAPERLESS Hackathon winners

New look, same great product! HelloSign is now Dropbox Sign.

We were absolutely blown away by the submissions that were entered into this year’s inaugural Dropbox Sign GO PAPERLESS Hackathon! We knew that we would get to witness a new level of brilliance when it came to building with the Dropbox Sign API, but never imagined the overwhelming turnout. Thank you to the 638 participants that were able to join us! While we were impressed by so many of the projects, we could only choose 5 across the categories. Take a look below at the hacks that took home a prize:
