Tsunagari AI, a Tokyo-based startup established in February 2025, is focused on developing artificial intelligence to address and eliminate social isolation. The company was founded by Hiroki Komazaki, a serial entrepreneur who previously founded and led one of Japan's largest non-profit organizations, Florence, for 20 years. This background in social problem-solving heavily influences Tsunagari AI's mission to create an empathetic AI that can act as a supportive social infrastructure.
The company's business model centers on providing AI-powered communication solutions to both public and private sector clients. For municipalities and local governments, Tsunagari AI offers a "Consultation AI" and a "Friend AI." The Consultation AI is designed to be implemented in public counseling service windows, operating 24/7 to ensure that citizens' calls are always answered, addressing personnel shortages while improving service accessibility. The "Friend AI" is a conversational agent that acts as a companion, capable of engaging in daily conversation and detecting early signs of distress, such as school refusal, bullying, or suicidal thoughts, thereby protecting the mental well-being of users.
For corporate clients, Tsunagari AI provides a "Colleague AI" aimed at employees in professions prone to workplace isolation, like truck drivers or home-visit nurses. This AI serves as a confidant for employees, and it reports risk signals to management in summary form to help prevent employee turnover. The company operates primarily within the Business/Productivity Software and SaaS sectors in Japan. In April 2025, Tsunagari AI secured approximately $421K in an angel funding round, with investors including Nobuhiro Ariyasu and the venture capital firm ANRI, to fuel its product development and expansion.
