NUMBER SEVEN SPORTS
Welcome to the home of NUMBER SEVEN SPORTS, a Dutch based athlete management company that represents soccer players during their professional careers as well as exploring commercial opportunities with them.
NUMBER SEVEN SPORTS was founded in 2022 by Paul de Koning and Tom Maas, about whom you can read more here.
The United States has been the benchmark for decades especially in women’s soccer and is worldwide considered as the undisputed most successful international team. In just the last 30 years alone the US women’s national team has collected an incredible amount of accolades, boasting Four World Cups, four Olympic gold medals and nine CONCACAF Gold Cups.
And even today, the US college system produces a ridiculous amount of talented players annually looking to be drafted. Unfortunately, with only a limited number of spots available, many athletes feel forced to turn to their work careers instead. One of the reasons why Number Seven Sports was founded is to provide college graduates with an alternative in Europe. With the presence of a number of strong leagues, you can still achieve your dream of becoming a professional overseas, all while experiencing a totally different culture.
