They didn't invent a new protocol or wireless standard. They're hosting a LoRaWAN and charging folks to use it. Presumably, Lime, for example, didn't actually need to change any hardware at all to use their service - their scooters already operate the proper hardware - they just bought LoRaWAN service from Helium instead of from say, Verizon. So I see no reason why it couldn't have been proven in a single city at the least.
