Just as in the USA where Lyft provides the major competition to Uber, I used to use Kapten. I see, however, that they seem to be out of business. Can anyone suggest an alternative company that provides cars (not marked taxis) that you summon with an app and know the price before you take them?

Also, Kapten offered Mercedes Metris vans that we used to and from CDG when we had a lot of bags so if you know a company that fits this bill as well, that would be great.
