Normaly me neither. In that particular case so it makes sense. Hardware development costs tons of money, especially when done by throwing highly paid engineers at the problem as the only idea. And when it is easier to get funding through a listing, but not enough yet, the company doesn't have a product yet but is public. Not an ideal place to be, for sure.
Maybe it’s just me. But I don’t consider publicly traded companies to be anywhere near a startup.
