Volunteer World provides a community marketplace for people to list, discover, and apply to international programs. Social projects can submit and self-administer their programs in an easy step-by-step process. Volunteer World presents all programs in the same design, levelling the differences in resource and providing grassroot projects with a fair chance to attract volunteer for their cause.

Volunteer World’s mission is to have lasting positive impact on the volunteer market by providing cost and service transparency of volunteer programs as well as significantly simplifying the search and application process.
