Selam everyone. For the Entrepreneurship group assignment, does anyone have reliable sources or reference materials about these entrepreneurs? - Dinku Dayas (Rift Valley University and other sister companies) - Belayne Kindes Companies - Betetehem Tilehun (Rebels Shoe) - Samrawit Fikru (RIDE) I'm looking for books, articles, interviews, or trusted websites—not a finished assignment. If anyone has useful references, please share them. Thank you!
