San Francisco’s Rock Health startup accelerator held its fourth semi-annual Demo Day at UCSF’s Genentech Hall Wednesday afternoon. Investors and journalists heard pitches from 14 startups working to introduce new health-related services for consumers and new ways to improve the efficiency of the U.S. healthcare system.
On the consumer side, one intriguing presenter was Beam Technologies, which is building a toothbrush embedded with motion sensors to detect how long a person has been brushing. A Bluetooth radio sends the data to a smartphone app. (Perhaps it should have been called the Bluetoothbrush.)
