It's great to see more heat pump options being developed, free from the assumptions of traditional manufacturers.
Combining air quality and ventilation with the same appliance is great (most houses lack systems for either of those). I don't see it addressed whether or not their fresh air systems will do heat-recovery. This is also a big energy saver when fresh air is being introduced, and would eliminate the need for a separate HRV/ERV system. So it's better to think of this as 3 systems in one: Heating, Ventilation and A/C (hence HVAC). Most houses have at best H and AC.
It will be very interesting to see how their heat pump sizing tools work. Right now, there is an epidemic of HVAC contractors installing massively over-sized heat pumps in a house by naively using the same rules of thumb they use for gas furnaces.
This often results in short cycling, higher-than-necessary electricity use, and ultimately discomfort. This is even worse when the heat pump air handlers and duct-work are installed in unconditioned spaces (common in temperate climates). In places with high energy prices (i.e. California) this results in huge energy bills.
The elephant in the room is of course the poor quality and leaky building envelopes that are commonplace across the country. This equipment can't solve that problem.
Wholeheartedly agree with the comment about oversized heat pumps - this also has the side effect of lots of homes in the Northeast being told they can't use their duct work without a major upgrade, or an unnecessary electrical panel upgrade.
