Zan Compute Put Sensors in the Restroom. Now It Wants AI to Run the Cleaning Shift.
The Santa Clara company spent a decade teaching buildings to notice an empty soap dispenser. Its next bet is harder: turning those signals into schedules, work orders and decisions that cleaning teams will actually use.

Fletcher Wilson is the co-founder and CEO of Throne Labs, the company behind the largest network of connected public restrooms in the United States. A mechanical engineer trained at Penn and Stanford, he spent nearly a decade building InterVene, a medical-device startup, before turning his attention in 2020 to a problem hiding in plain sight: the disappearance of clean, accessible public bathrooms. Throne's solar-powered, sensor-equipped units deploy in under two hours, are free to use, and have logged more than a million uses across 20-plus cities. In October 2025 the company raised an initial $15 million Series B led by Brentwood Associates.
Throne Labs
Throne Labs builds solar-powered, sensor-equipped public restrooms that cities and transit agencies deploy on demand. Each self-contained unit pairs a flushing toilet, running-water sink, baby-changing station and free menstrual products with 21 sensors that feed real-time data on usage, cleanliness and maintenance, turning the long-neglected public bathroom into a measurable, turnkey service. Founded in Washington, D.C. in 2020, the company operates across four regions and more than 20 cities and is rolling out restrooms for LA Metro ahead of the 2028 Olympics.
