Documented cause
Comfy, a Berkeley-based smart building workplace comfort app, raised $20M and was acquired by Siemens Building Technologies in 2018 for an undisclosed sum. Post-COVID, corporate office occupancy collapsed and enterprise demand for comfort personalization tools evaporated. Siemens shut down the Comfy product line in 2022 after occupancy rates in client buildings failed to recover, rendering the platform's per-seat model unviable. Co-founders Andrew Krioukov and Burak Merdenyan had exited shortly after the acquisition.
Lesson
