Once the Submission Period has ended, you may not make any changes or alterations to your Submission, but you may continue to update the project in your Devpost portfolio.

Modifications: After the Submission Period. The Sponsor and Devpost may permit you to modify part of your Submission after the Submission Period for the purpose of adding, removing or replacing material that potentially infringes a third-party mark or right, discloses personally identifiable information, or is otherwise inappropriate. The modified Submission must remain substantively the same as the original Submission with the only modification being what the Sponsor and Devpost permits. 


6. Judges & Criteria.

Eligible Submissions will be evaluated by a panel of judges selected by the Sponsor (the “Judges”). Judges may be employees of the Sponsor or third parties, may or may not be listed individually on the Hackathon Website, and may change before or during the Judging Period. Judging may take place in one or more rounds with one or more panels of Judges, at the discretion of the Sponsor. 

Stage One) The first stage will determine via pass/fail whether the ideas meet a baseline level of viability, in that the Project reasonably fits the theme and reasonably applies the required APIs/SDKs featured in the Hackathon.

Stage Two) All Submissions that pass Stage One will be evaluated in Stage Two based on the following equally weighted criteria (the “Judging Criteria”):

Entries will be judged on the following equally weighted criteria, and according to the sole and absolute discretion of the Judges:

  • Design
  • Is the user experience and design of the app easy to interact with? Simplicity is key! Remember we are working against pen & paper.
  • Quality of Idea & Potential Impact
  • How creative and unique is the Project? How much value is created for businesses? Users? Does the project innovate past signing? If yes, what's the possible impact of the processes being disrupted?
  • Implementation
  • What is the extent to which the Dropbox Sign API and AI tool were integrated? How realistically could the technical implementation be integrated?
  • Presentation
  • How well is the Project pitched? Does the demo contain a live walkthrough of the user experience and how the Dropbox Sign API and AI tools are used? Does the demo communicate value?

The scores from the Judges will determine the potential winners of the applicable Prizes. The Entrant(s) that are eligible for a Prize, and whose Submissions earn the highest overall scores based on the applicable Judging Criteria, will become potential winners of that Prize.

Feedback Submission Criteria. Eligible Feedback Submissions will be evaluated based on the completeness, viability, and potential impact of the feedback.

Tie Breaking. For each prize listed in Section 8 below (each a “Prize”), if two or more Submissions are tied, the tied Submission with the highest score in the first applicable criterion listed above will be considered the higher-scoring Submission. In the event any ties remain, this process will be repeated, as needed, by comparing the tied Submissions’ scores on the next applicable criterion. If two or more Submissions are tied on all applicable criteria, the panel of Judges will vote on the tied Submission.


7. Intellectual Property Rights.

All Submissions remain the intellectual property of the individuals or organizations that developed them. By submitting a Submission, Entrants hereby grant the Sponsor a non-exclusive, royalty-free, fully paid-up license to use such Submission for the purposes of judging the Submission.
