Not sure the target market is for this since it's between airports. The Palo Alto to SFO one doesn't really help you get into the city because much of the traffic you'd have to drive through is between SFO and downtown. I guess they couldn't get rights to land somewhere downtown (after a bit of research it actually looks like there are no active heliports in SF except one at UCSF in the Dogpatch. Color me unsurprised…
I don't think they target PASF traffic. This looks more like a last mile connection for people who want to get to Palo Alto, from outside of bay area. Given how many VCs are there, there's some potential market for it.
