Butlr: Revolutionizing Smart Buildings with Privacy-First Sensors

Innovative Approach to Smart Building Technology

Butlr, a company founded by former MIT Media Lab researchers Jiani Zeng and Honghao Deng, is revolutionizing the concept of smart buildings with their privacy-first approach. The company has developed low-resolution thermal sensors and an analytics platform that can understand how people use spaces without compromising individual privacy 1

"We have this vision of using the right technology to understand people's movements and behaviors in space," says Zeng. "So many resources today go toward cameras and AI that take away people's privacy. We believe we can make our environments safer, healthier, and more sustainable without violating privacy" 1
