Executive intra-city hops
Same thing that most commercial helicopters are used for, outside of oil rigs.
Presumably the key improvements are noise and glide slope (most cities have very strict rules about where helicopters may fly), running costs and pilot training, as VTOL aircraft training is simpler than helicopter pilot training.
The intention will be for execs to fly into a major airport then take one of these to their final destination, instead of them having to potentially mix with those dirty "people" on the ground.
