It may not look like it today, but HVAC controls manufacturer Danfoss was started by Mads Clausen in the basement of his parents’ Nordborg, Denmark, farmhouse in 1933.
By 1939, it was exporting to other countries in Europe and had a foreign sales office in Argentina 10 years later. Today, Danfoss has 23,000 workers and sells in more than 100 countries, including large presences in China, Germany, Russia and the United States.
