Oh man, I remember about 10 years I got so annoyed with my buys-ass gym and having to wait in line to use a machine that I came up with the idea to track real-time gym attendance and machine usage. It was going to be called WaitLift. It never went further than that awesome name.

Density (software) engineer here. Our sensor uses active infrared lasers to read depth, and it classifies "persons" with a deep-learning algorithm that runs on the device.
Very cool!

I wonder how true this statement is, given how accurately we can now identify people based on just their walking gait – see "Human Gait Recognition Based on Gait Energy" paper[1].
The 'sensor' view on density.io that attempts to illustrate this point appears to convey just as much as the sample images in the paper.
I remember when this was a Show HN, it was my first comment to say that the homepage didn't work for me in an old version of Firefox (and the developers reached out, thanked me for the report, and fixed the problem). https://news.ycombinator.com/item?id=9878597 Now so many businesses needs to count capacity, and they're perfectly positioned with 5 years of experience in the space. Amazing foresight (and/or a bit of l…
Not sure if this is really what happened (no reason not to trust them; but sometimes founders' stories are rewritten), but it's just so cool to start like that and become a large, well funded startup.
A pretty cool product and very useful! I hope something like this becomes super wide spread (maybe with competitors as pricing is a bit wack) so we can always know how busy our local stores etc are before heading out.
This is a great example of taking an innovation and positioning it as a solution to a real, painful, and timely business problem. Many startups in their place try to come up with some original messaging and as a result overcomplicate everything. Density keeps it simple: "Count people."
