Welt

Welt Corp is a digital health technology company that has evolved from its origins as a smart belt manufacturer into a digital therapeutics company focused on sleep medicine. The company's current flagship product is SleepQ, a prescription digital therapeutic device for insomnia treatment that delivers cognitive behavioral therapy for insomnia (CBT-i) through a mobile application. SleepQ is approved by Korea's Ministry of Food and Drug Safety and has received CE certification for European markets, with global clinical trials underway in Germany. The six-week program provides personalized sleep schedule prescriptions based on sleep restriction therapy, 1:1 phone consultations with sleep counselors, educational content designed by psychiatrists, and an AI sleep expert available for consultation from 10 PM to 5 AM. Clinical results show participants fell asleep 45% faster, with effects lasting approximately 24 months, outperforming medication in long-term efficacy. The program also improved anxiety and depression symptoms. Founded in 2016 as a Samsung Electronics spin-off and headquartered in Seoul, South Korea, Welt has raised approximately $10.1 million in Series C funding from investors including Envisioning Partners, Korean Development Bank, IMM Investment, Shinhan Venture Investment, and Handok.
