If not Space X who? Probably Arian Space. Arian 5, was designed with human flight in mind, and apart from blowing up a couple of times in the early days is still able to take a capsule, and a trunk load of luggage and put it into either low earth orbit, or head straight for the stars.
Cheaper than NASA but not as cheap as Space X, but then it does pay taxes…
Now Arian 6, has been scaled back to be cheaper but does not go nearly so far, and does not have the same space at the top for capsules. Strange world.
