On my street in SF that has a dead end, cars keep coming up looking for parking and on weekends they usually find nothing. But they get stuck turning around and cause a mess. Could I use Density to count cars and display number of empty spots at the entrance of my street?

Can't count cars at the moment, unfortunately. But there's some cool tech from Flocksafety and other camera solutions.

Do you worry that you're taking money at a valuation that's predicated on artificially and transiently elevated demand? It doesn't sound like you have a business compatible with the VC hyper-growth model, outside of the present extraordinary circumstances. It also feels intuitively like many person counting use cases are satisfactorily addressed by far simpler and lower cost heuristics such as, for example, Google li…

You're asking good questions about raising capital but the outcome was a rare circumstance where all cofounders, previous investors, new investors, current employees, and the exec team are thrilled. There's a lot to do but the round was right-sized as it was the same amount we planned to raise pre-pandemic.

Lower cost systems like Google's Popular Times, are not as accurate as they seem. The next time you see a graph on google, you'll notice there's no y-axis. It's a clever way to look like actuals when it's relative to itself. Also we have units in many GPT locations. They're not accurate. On the vc returns thing ¯\_(ツ)_/¯ We'll see.

How does the accuracy of your system compare to ARKit’s people/skeleton tracking with the LiDAR Scanner in the new iPad Pro?

I wonder how much more accurate this solution is compared to a simple IR beam across the entry. Is the extra HW and SW complexity needed to implement a computer vision solution worth the increase accuracy? I suppose the answer would depend on the use case. Mom-and-pop shops might only need an IR beam, if that, while megacorps that optimize costs down to the penny might have use for exact customer trends so they can d…

Basic IR beam solutions cannot tell the difference between someone going in the store vs someone going out, so keeping a real-time count of occupancy is difficult (or impossible). They also struggle with two people going through a doorway at the same time (counted as one entry vs 2).

Can confirm

A two beam setup would allow differentiation between entering and exiting of single clients. Then the question comes down to how often do 2+ people cross the beams at once, and does that have enough of an effect on the aggregate statistics, if it was taken into account (e.g. count each crossing as 1.1 people, if 10% of beam crossings are 2 people)?
