About Density:

Density’s mission is to measure and improve our footprint on the world.

We help companies understand how their workplaces are used. We do that by observing behavior in the office through our highly accurate and always anonymous sensors. In other words: where are people actually spending their time? We translate that data into actionable, opinionated insights that help companies increase the financial and experiential performance of any workplace.

Today, we work with companies from Fortune 500s to high growth innovators in technology, financial services and healthcare, occupying more than a billion square feet worldwide. And we’re in it for the long game: what if we knew more, created better spaces, and could build cities that worked and felt better?

That’s where you come in...
