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...

What We Do
At Density, we believe cities would look different if they knew how they were used. Understanding our relationship with physical space empowers us to reimagine what the built environment can be.
11,370 new buildings are being built every day and 39% of global carbon emissions come from existing buildings. If we want to build a more productive, sustainable future, we have to measure all those buildings. We work with the Fortune 1000 to measure and improve their offices, buildings, and portfolios. Density’s data creates more efficient and productive workplaces for people and the planet.
We’re on a mission to measure and improve our footprint on the world.
