That is an EVT stand, very nice, made by Efficient Velo Tools of Portland, OR. Efficient Velo Tools (EVT)
They are expensive but probably the best. they make a counterweighted one for ebikes.
I was considering upgrading to the EVT stand and decided that I did not have enough room. I already have a Park Tool shop version and realized that I could use the EVT Right Arm Repair Clamp in the Park Tool stand. EVTs clamp is designed specifically for holding bicycles by the seatpost. It does a much better job at it than the Park Tool clamp.
