 From the beginning DYO and later Sadolin ve Yasarin and DYOSAD the joint ventures were run by Selçuk Yaşar (oldest son of "Durmuş Yaşar") – in close cooperation with Dan Alexander MacGregor Sadolin, (the only son of Gunnar Asgeir Sadolin, the founder of "Sadolin & Holmblad"), who was joint president and international CEO of "Sadolin & Holmblad".In 1979, 25 years after the first factory establishment, DYO and DYOSAD in Turkey had become bigger than the domestic paint and ink activities in Denmark of "Sadolin & Holmblad" – in terms of both net revenue, net profit and number of employees.However, DYO and DYOSAD never counted for more than 10% of the net revenue, net profit or number of employees of the entire "Sadolin & Holmblad " group, which were active with more than 60 factories sites in over 40 countries, and had sales in more than 100 countries.
