Pavel Paska, the sole owner of the company, established the business in 1991 as the very first player agency in the territory of what is now the Czech Republic (former Czechoslovakia). Earlier on, from 1988 until 1990, Pavel Paska organised a number of major transfers involving Czech national team players, such as František Straka (Borussia Mönchengladbach), Tomáš Skuhravý (Genoa FC), Ivan Hašek (Racing Strasbourg), etc.

ISM s.r.o. has helped significantly to many former and current Czech national team players in building their successful careers by organising their transfers to world leading clubs, such as Karel Poborský (from Slavia Praha to Manchester United), Patrik Berger and Vladimír Šmicer (from Slavia Praha to Borussia Dortmund and Racing Lens, respectively - both transferred to Liverpool FC later on) and last, but not least Pavel Kuka (1.FC Kaiserslautern).
