In 1988 ONCE established the ONCE foundation (Spanish: Fundación ONCE) to provide professional training and employment, to eliminate architectural, urban and communication barriers and promote "Digital Solidarity", web-based services for people with any disabilities. The Fundación also has its own business arm, Fundosa, with companies dealing with accessibility, industrial laundering, and so on.
The Fundación is active in the Paralympic movement and is a founding partner of the European Network for Accessible Tourism (ENAT), an international organization set up in 2006 to promote accessible tourism.
The Fundación has attracted support from the Spanish royal family. In May 2010, Princess Letizia presented awards at a Fundación awareness-raising event. In March 2011, the Princess presented the Fundacion's DISCAPNET awards, celebrating innovation in accessibility.
