I skimmed through the last 10Q and actually they do mention Tier 1:
"In January 2015, we signed a Development and License Agreement with one of the top consumer electronic companies in the world based on total worldwide revenues. The agreement is milestone-based and while there are no guarantees that the WattUp® technology will ever be integrated into our strategic partner’s consumer devices, we have achieved some milestones, as reflected in our 2016 Engineering Services revenues. We expect to make continued progress toward achievement of significant new milestones that we expect will result in additional Engineering Services Revenue. Ultimately, if the customer chooses to incorporate our technology into one or more of its consumer electronic products, we expect to recognize significant revenues based on the WattUp® technology."
