Great questions @sebo58
For your first question regarding partnerships. I haven't heard of any yet, but they will be announced soon I'm guessing. Having already two established and fast growing companies such as SkyCell and Food Guardians almost already guarantees upcoming partnerships.

For your second question. Sure GPS as a tracking method is still possible to use in my opinion. But having IoT sensors on the other hand, which come with a way better technology can be more profitable on the long run. IoT sensors can additionally to real time tracking also measure data like heat and provide many more accurate data on the product and containers. With further development IoT sensors seems to be the all-in-one solution for essential data retrieval.
