Sunu is a technology company that specializes in creating innovative solutions for individuals with visual impairments.

Operating in the assistive technology market, Sunu serves clients who seek greater independence and mobility in their daily lives.

The Sunu Band uses advanced sonar echolocation technology to detect objects up to 16 feet (5.5 meters) away. It then provides haptic vibration feedback to inform the user of the proximity of obstacles, thereby reducing accidents and enhancing personal awareness. This device complements traditional mobility aids such as white canes and guide dogs, offering an additional layer of safety and confidence.

Sunu's business model revolves around the sale of the Sunu Band, which is priced at $299.00. The company also offers a mobile app that allows users to update, customize, and add new features to their Sunu Band, ensuring continuous improvement and adaptability to the user's lifestyle. Sunu generates revenue through direct sales of the device and potentially through app-related services.

Founded in 2013, Sunu is a Y Combinator company and a Mass Challenge alumnus. It has received recognition for its innovative approach, including a gold award in 2014. The company's mission is to empower independence through technology that bridges the access gap for individuals with disabilities.
