Benefit Corporation

 
 

Great medical devices can be affordable. Today, 80% of medical devices are designed for only 20% of the people who need them. To fit tighter budgets and rougher environments, our product design process and company structure are different.

Participant is for-profit company registered as a Benefit Corporation. Here are a few of our commitments to social impact.

  • Our products are evaluated by outside experts to confirm that they pass international quality standards.

  • We monitor and report the actual efficacy of our products. Our participants tell us if we are succeeding!

  • Our management is evaluated by our board using environmental and social metrics - as are all employees.

  • All products have lifecycle impact assessments. We do not do ‘planned obsolescence’.

  • 5% of our profits are donated to our non-profit partners so they can serve more people.

  • We all participate in the company's success. All employees are owners regardless of where they live.

Keoke King

Keoke’s first encounter with disability was while being cared for by his grandmother. Her assistive products, a cane and a rudimentary wheelchair, were bulky and did not function well for her daily activities, especially outdoors. To design projects, Keoke brings a user-centered approach and attention to affordability. He loves to find market-based, scalable solutions that serve basic needs and his career in international development has taken him to seventeen countries for roles in marketing, supply chain, product development, and sales. In his last role, Director of Social Enterprises at UCP Wheels for Humanity, he launched CLASP, which is a supply chain solution designed to improve the access and affordability of appropriate assistive products globally. Previously, Keoke was Marketing Director at Whirlwind Wheelchair after his MBA studies at San Francisco State University. Keoke lives in San Francisco with his wife, Chris. Keoke on LinkedIn
