​​The Stumpf Fountain Company has been building outdoor fountains for municipalities, exhibitions, hotels and banks since 1968. By the 1980's, Stumpf has grown into a global fountain design specialist and some of the largest fountains in the Middle East and Europe have been planned and constructed by the company. In 1990, the Stumpf Fountain Company built Europe's largest music fountain inside an amphitheater in Prague, Czechia for 6,000 spectators. Today, Olly Stumpf creates the next generation of music fountains under the brand ONYX FOUNTAIN, named after his son Ythan Onyx, as part of the 'M' Family Office Group.
