I can talk to my coworkers at Destino (web shop) to see if we can contribute officially to development and/or infrastructure.
Some others to consider:
Dji - Drones / Cameras
Transportation/Logistics companies like Posten, Bring, SR-Transport - for route information and "ground contacts"
Local public transit - for transportation and route information
OpenStreetMap for traffic data and route visualization
Komplett.no and Elkjøp - They might be willing to offer ground-teams discounts on mobile hardware, such as chargers and cameras
Aftenposten - Media attention
The Ingress Team at Google - They have so much map data that would be useful and such a wide user base, that they would definitely be an asset for raw data
Local geocaching groups - Same as the Ingress Team at Google, lots of raw data and people that spend time during the day and night finding caches of data at various points on maps using mobile apps.
Collection of ideas of who can sponsor what to get the project off the ground.
