Refinement

During the Refinement Phase, 29 shortlisted concepts across both the "Public" and "Non-Public" channels are invited to develop prototypes, plans to scale their business model, and other demonstrations of the solution’s ability to satisfy the goals of the Challenge. 

Participants will be matched with an industry leading mentor to support the iteration and refinement of their concept. 

Final application materials are due by: January 17, 2019 at 5pm PT.

During this phase, the Consortium may ask technical questions of your submission. Any request you make for an NDA could be considered at this time. If this applies to you, please complete the NDA request form included in the submission questions for this phase. 

Please review the required Refinement Phase submission questions before getting started.
