Who are CIO's major customers that are responsible for this impressive growth?

Has there been any clarity as to who the US IOT automotive industry, or even IOT retail solutions customers are?

And given the amount of product manufacturing and operating costs ($2,551,000 for the first 3 quarters) does the $31,000 spent on advertising and marketing (also for the first 3 quarters) seem reasonable? It seems like a low amount in the context of the manufacturing and operating costs, along with the $3,469,000 in customer receipts we've received.
