Lark builds wearable and app-based products for sleep and health tracking. It launched a wearable silent alarm onstage at TechCrunch Disrupt in 2010 and later expanded its lineup to include a sleep coach called Lark Pro and a general device and app called Larklife, announced in October 2012. Larklife was described as a way to track diet, exercise, sleep and deliver actionable recommendations and has been sold in Apple retail stores and elsewhere. The company is led by CEO Julia Hu and the SEC filing identifies Weili Dai as a member of its board. According to an SEC filing, Lark is raising $3.6M and has reported $3.1M raised so far. Lark previously raised $1M from Lightspeed Venture Partners, CrunchFund and others. Lark offers a silent waking system that uses an iPhone app paired with a small Bluetooth-enabled band worn across the wrist to vibrate users awake without loud alarms. The app turns the phone into a nighttime alarm clock and the band’s vibration aims to avoid disturbing partners. Since launch the company added sleep monitoring, plus personal sleep coaching and a personalized seven-day sleep assessment to advise users on sleep patterns. Lark worked with Harvard Medical School sleep expert Dr. Jo Select to test the app with students, producing positive results and reports of better partner sleep. The product is sold online and will be available in Apple retail stores in the U.S. and Canada starting June 14. The startup has raised $1 million in funding from Lightspeed Ventures and other strategic investors and sells the alarm with sleep monitoring for $129 and a version with coaching for $189.
