1. Contexts in which a Shabbos goy is a permitted solution are quite restricted - it's not a "get out of Shabbos free" card. 2. A Shabbos goy, being human, has agency, while a device does not have agency, leaving the person using the device with responsibility for making the device do something.

Such a company is not entirely unimaginable given sufficiently roundabout sensing mechanisms. It could be especially useful in Israel due to the majority of the population being Jewish and with many neighborhoods and towns nearing 100% Jewish residents. Mostly, though, religious Jews in Israel are just used to not having a Shabbos goy as an option. That said, the one time I found myself really stuck in a bind where a Shabbos goy was the only reasonable solution, I was fortunate enough to see a non-Jewish taxi driver pull over within minutes of going outside to look for one.
