Prosper has always been a voluntary trainer for children in dance and sport. Two street soccer tournaments have been organized in Lomé, Togo by Prosper Koami Gbetoho, who now lives in The Netherlands since January, 2008. Prosper organized these tournaments in October, 2008, and September, 2009, during his visits to his homeland in Togo. He did this in his own time and with his own small budget as a private person. As a result, he founded Elayi Foundation on December 16, 2009.
