Density, an analytics platform for measuring and optimizing workplace performance, has secured $125 million in Series D funding led by existing investor, Kleiner Perkins. Other new investors include Altimeter Capital and Lachy Groom of LGF, with participation from existing investors 01 Advisors; Upfront Ventures; and Founders Fund.

Density measures how people use space in real-time without invading privacy. Using proprietary depth sensors and deep learning algorithms, the platform accurately and anonymously counts people in real time. Organizations use Density to improve efficiency and enhance occupant experience in buildings, workplaces, and real estate. Unlike a camera, Density's platform doesn't capture personally identifiable information and is purpose-built for accurately measuring how people use physical space. Together, Density's customers manage over 1 billion square feet of real estate.
