Their site looks like its there to attract investors rather than sell any kind of real product.. i might be wrong but i don't think this is going to amount to anything, shame.
I don't see how 2 tons are being lifted from such a low and thin surface. The whole thing looks more like a Kickstarter than a real product.
Edit: Nope this is 100% legit
Example of an electric one: https://youtu.be/w7MG3DOwAhQ
Quite close to this Stanley device. They claim capacity of 3,5 tons. Forks are not as long, but the mechanics seem such that extending them should not be a problem.

Also they seem to use ectorparking.com at Lyon, are you affiliated with Ector?
Have you had any communication with tire manufacturers about how you lift the car that way?
Wouldn't that put unusual stress on the tire plies? Maybe once or twice might be OK, but if someone did this to tires 500 times a year (e.g. commuting to work, once at arrival at garage at work, once at departure from work) would the tires still be OK?
