I have long been interested in the work of entrepreneur Dennis Crowley. He is perhaps best known as the co-founder of Foursquare, which popularized location "check-ins." But he's created a bunch of other stuff too. The common theme is that his products exist at the intersection of tech and cities (the physical world), which is probably why I've been so interested over the years.

Check-ins, for example, allowed you to say to all your friends, "hey everyone, I'm at this bar." It was a way of checking if anyone you knew was there too, or close by, and also a way of inviting your friends to come join you if they were so inclined.

This was extremely popular for a period of time, but then kind of fizzled out, and Foursquare was forced to pivot and try a bunch of other things. And in the end, this "problem" of augmenting the physical world with our social graph (and other information) never really got solved. I mean, this is broadly the promise of augmented reality.

Thankfully, Dennis has a new company (Hopscotch Labs) and a new tech/city product called Beebop (which is currently in private beta). Here's how it works (excerpt from this Crazy Stupid Tech interview):

It's an iPhone app. There's not much to do in the app, there aren't a lot of buttons to press. Once it's installed and you set the permissions, every time you put on your headphones — your AirPods or any other headphones, it doesn't matter—it chimes and says, "Beebop's been activated." (Beebop is the first project from the company, Hopscotch Labs.)

Then as you walk around the city, it will tell you things about certain places. Eventually, if I walk by a place where my friend was, it tells me that Alex was here two days ago. If I walk by a place and someone's inside, it tells me that Max is inside that place. A lot of it is still under development. Eventually, people leave a comment at a place. Imagine Twitter. It is as if you leave a tweet and you stick it in the ground. When you walk over it, you hear it.

So like before, it's about experiencing cities:

It's been a long time since I built something. What's different now? AI is what's different. You know what's different? Everyone's on their phones all the time. Back in my day, we made stuff for the streets. You would use your phone, you'd put it away, and stuff would happen. Where are the people making that stuff anymore? All we make is stuff that makes you look at the screen. Let's make stuff that gets you out in the world, where you're not glued to the devices. You're out there doing stuff. Big companies out there aren't going to make stuff like this.

The key idea here is that augmented reality doesn't have to just be visual. Visual also requires somebody to figure out a cool set of glasses that people will actually wear out in public. Who knows when this happens, though I do think it will eventually.

So what Dennis is doing is making something that works today -- with audio. This has been called the poor person's augmented reality, but I think that's selling it short. This is really clever. And once again, it's fundamentally connected to how people live in and interact with our cities.

This week it was announced that Foursquare and Factual are planning to merge. Both use location data to improve advertising and overall business intelligence. But unlike Foursquare, Factual doesn't have a consumer-facing app. So most of us probably haven't heard of them before. But they are some of the data and tech behind many of the companies that we do all know, including Starbucks.

I have long been fascinated by location-based startups -- like Foursquare -- because they are inherently spatial. And how we move about our cities and spaces is rich with information. Companies want this data because, among other things, it is a register of intent. Me going somewhere signals certain things, including where else my kind might want to go.

But location data can also be used for many other things beyond advertising and retail analytics. Foursquare has started sharing aggregated and anonymized foot traffic data with local governments and public health officials in the fight against COVID-19. That data is currently powering http://www.visitdata.org. Foursquare is also publishing a regular insights report.

Here is a chart from them showing casino visits in Clark County since March 1:

In many ways this chart is fairly obvious. In fact, it actually mirrors my own journey into isolation. After the NBA shutdown on Wednesday, March 11, things started to feel pretty real and on Friday I was working from home. But there's a lot more that can be done with location data and there's a lot more that will be done going forward. I am confident that will help not only business, but also society more broadly.

The CEO of Foursquare -- Jeff Glueck -- published an interesting op-ed in the New York Times today, calling on Congress to regulate the location data industry. Currently, there are no formal rules in place.

In case you're not aware, Foursquare is one of the largest independent companies operating in this space. I have written about them many times before on the blog.

Here's an excerpt from Jeff's op-ed explaining why this matters:

But location data can also be abused. Bounty hunters were able to buy the current location of a cellphone for $300, Vice reported, because telecom companies sold the real-time location of phones to shady companies. And apps that track location data may turn around and sell that data, revealing someone’s every movement — whether it is to a retail store, an abortion clinic or a gay bar. Bloomberg Businessweek recently reported on a company with thousands of cameras selling car locations to debt collectors and others; there is no “opt-in” involved, and it’s illegal in all states to cover your license plate.

I am writing about this today because I think it's relevant to city building. Location data is inherently spatial. It is how we exist in cities. So it shouldn't come as a surprise to any of you that this is valuable information -- hence why it is being abused.

Here we have a company advocating for more, not less, regulation. They, of course, want it to be sensible. But I still think it says things about the current location data environment. To learn about the specifics of what Jeff is proposing, click here.
