I don't think this is nearly at the stage of "corporate customers putting into serious trust"

Buildjet (the parent company) looks to be a pretty small company with currently modest revenue[1]. I agree that the absence of people on both webpages is sort of odd. I think it make more sense for their original service (CI workers) than it does for a hardware product.
