OpenSesame

is an online marketplace for corporate training. Their goal is to make buying and selling corporate e-learning courses as easy as downloading a song from iTunes. The marketplace will be crowdsourced with an aim to provide a fresh and broad selection of courses. Sellers can add courses just by setting up a profile, uploading a course (.zip, SCORM, AICC, or video file), entering a description and pricing, and validating it to make sure it will display in any learning management system. After the course is validated, OpenSesame promises to review and publish your course to their marketplace within one business day.
