Looking Ahead

People Counting Platform

Density's people counting platform uses cutting edge hardware and software to measure how people are using space in real time. The platform consists of sensor technology combined with analytics and a modern cloud infrastructure. The sensors are not cameras, and are able to count and measure people anonymously. The platform provides a real-time, robust infrastructure for knowing how space is used.

Today there are big questions about privacy and what our smart buildings should or should not know about us. Density believes it shouldn't always be about tracking individuals throughout a space aka active surveillance. Privacy is one of Density's core tenets, and the sensing devices don't capture any personally identifiable information. The entry sensor, fixed at a point of entry, uses computer vision and captures depth data to count people as they pass through chokepoints in a building. Leveraging machine learning and AI the technology is able to learn over time and accurately distinguish humans from other objects. The open area sensor utilizes a pioneering radar technology to measure people in unbounded space. Placed on the ceiling of any room, these sensors can measure the usage of anything, from a conference room to a chair or couch.

Analytics and Cloud Infrastructure

Today Density is working with some of the largest holders of corporate real estate. Think large tech companies, universities, and hotel chains. They are leveraging the data to understand the utilization of all spaces in real-time, and historically, across their portfolio, often leading to cost cutting for underutilized space. Today, the data can also be used to manage real-time occupancy, incorporating alerts when certain capacities are reached. There is a lot of room for efficiency gains given the fact that over 41% of all corporate real estate leased or owned is vacant, but paid for.

2nd & 3rd Order Effects

Today corporate real estate serves as a great beachhead market for Density. They can get their devices into a lot of rooms quickly, but it's the 2nd and 3rd order effects that could have a profound impact on how we use space in the future. If Density succeeds in its mission, may lead to less buildings getting built which will effect climate. It could lead to a reallocation of space to those who are in greater need of it. These days, affordable housing is a major concern in large cities like San Francisco and Los Angeles. Information is power, and the more data we have about how our spaces are being used, the better we can make use of the space in the future.

Team & Culture

Density aims to build a world class team. Over the past 6 years they have seen 93% retention. The founding team is fully intact since the idea began with the goal of measuring the line at a coffee shop in 2014. Diversity is something they value greatly, and given the range of their technology, they are sure to bring together an exciting mix of skills and personalities to solve a problem that just might change our cities for the better.
