Butlr lands new cash to put people-detecting sensors in the office – TechCrunch


Butlr, an MIT Media Lab spinout developing sensors that use body heat to estimate office occupancy, today announced that it raised $20 million in a Series A round with participation from Carrier Global Corporation (a strategic investor), Tiger Global, Primetime Partners, E14, Unionlabs, Hyperplane and Tectonic Ventures. Co-founder and CEO Honghao Deng said that the proceeds will support product development and expanding Butlr’s 50-person workforce, specifically its go-to-market team.

Deng asserts that many companies are flying blind when it comes to real estate. While they added heads during the pandemic, they now face economic headwinds that could — or already have — prompted hiring freezes and layoffs. With the lack of clarity on whether they should lease more space, reduce their footprint, use co-working spaces or all of the above, Deng said, it’s resulting in paused construction and office redesigns as companies figure how to accommodate employees’ needs while cutting costs.

According to a March AT&T poll, 72% of businesses lack clear hybrid work strategy.

“The pandemic brought home the need to understand occupancy and utilization data for real estate executives,” Deng told TechCrunch in an email interview. “Whereas pre-pandemic, they could assume everyone would be in every day of the week, that’s no longer the case. Real estate and workplace executives need to establish a new baseline and make data-driven decisions given the dollars at risk with regard to office space and employee productivity.”

He points to Butlr’s technology as the solution, which uses thermal sensing and AI to provide data on space occupancy and historical activity. The company’s sensors — which Deng and Butlr’s other co-founder, Jiani Zeng, developed while at MIT — don’t require networking equipment other than a Wi-Fi connection and hub and have a claimed “multiyear” battery life. Via a cloud dashboard and API, Butlr displays information like which areas of an office are the busiest and how many people have entered and exited a space.

One key advantage of Butlr’s sensors is that they preserves privacy, claims Deng. The palm-sized hardware captures only “temperature pixels” and nothing else, unlike, say, cameras.

“There are various sensing modalities to understand space occupancy and utilization, ranging from the old-school time and utilization studies (i.e., consultants with clipboards and clickers) to using Wi-Fi access points to cameras and more exotic lidar solutions,” Deng continued. “Each sensing modality has its advantages and limitations due to physics. The reason customers are choosing Butlr has to do with privacy, cost of ownership, time to value and flexibility.”

It’s worth noting that Butlr isn’t totally unique in its privacy-preserving approach. Density, a competitor, has long claimed that its sensors can only capture occupancy data and not information that might be used to identify a person.

Still, Deng says that Butlr’s hardware design and space-designing software was what won over many of its early customers.

“Commercial real estate and senior living are the first two industries to embrace Butlr’s technology, and the company is exploring opportunities for people sensing in additional markets,” Deng said. “Beyond using occupancy data for real estate decisions and planning, it’s also being used to understand and foster a better employee experience, and for smart buildings and facilities management. For instance, our partner Infogrid’s smart cleaning solution uses Butlr occupancy data to …….
