Sto’s success story started in 1954 in the German town of Stühlingen. Back then, Fritz Stotmeister – the son of Wilhelm Stotmeister – had a sixth sense to invest in a new product at the right time: an organic render from Swiss inventor Silvio Pietroboni. Ispo-Putz KG was founded based on the new synthetic resin render. From what was once a three-man operation, Fritz Stotmeister created an international company which now has more than 5700 employees worldwide.
