–direct relevance to the core problem/addressing the core problem;

–uniqueness of the recommended solution;

–use of ai systems;

–ease of implementation (e.g. feasible to implement within one year).

–quality of code

–Does this project expand the accessibility of Harper? (ex. large ecosystem integrations,

non-developers can utilize the power of Harper, improve accessibility for developers)

•         Is this project production ready?

•         Ease of use of project

In the event that a winning project is the result of a team effort, Harper may, in its sole discretion, recognize the team collectively as the winner and coordinate prize fulfillment accordingly.

Amendment to Hackathon Rules (Ownership and Monetization Rights)

Ownership of Entries (Amended)

1. Participant Rights:
   Participants retain the right to independently develop, commercialize, or otherwise monetize their project submission, provided that doing so remains within the bounds of Harper’s existing software licensing, APIs, and intellectual property protections.
2. Harper’s Rights:
   Harper retains a non-exclusive, perpetual license to showcase, publish, and demonstrate submitted projects for promotional, educational, or community purposes. Harper may reference or reuse elements or concepts from any submission to enhance its platform or related products, but will not directly commercialize or sell a participant’s overall project without express written consent from the participant(s).
3. Clarification:
   This amendment ensures that while Harper maintains rights to use and display submissions, participants also maintain the ability to extend, monetize, or spin off their work, as long as it does not violate Harper’s core intellectual property or licensing framework.

Amendment Added: October 27, 2025
