Documented cause
Chui raised $3.9M to build a smart doorbell with facial recognition, allowing homeowners to know who was at the door before opening. While Chui was developing its product, Ring launched and scaled aggressively, Nest entered the category, and the smart doorbell market was captured by well-funded incumbents with broader smart home ecosystems. Chui ran out of runway and shut down in 2016 without achieving distribution at any meaningful scale.
Lesson
“Hardware startups in consumer categories lose their timing window faster than software because manufacturing, distribution, and retail shelf deals take 12-18 months — enough time for a funded competitor to commoditize the category.”
