Member Spotlight: TitanX

TitanX’s history involves several different companies. Its roots go back to 1895 when JW Thorell, a Swedish blacksmith, started his own business in Linköping. Then, in 1914, the Gabrielson Car Parts Company opened in Jamestown, New York. Another plant was founded in 1953 in Mjällby, Sweden. Those three plants were eventually acquired by Blackstone, then Valeo. Then TitanX was born in 2008. TitanX’s headquarters are in Sweden. There are also facilities in Brazil, Mexico, and China as well as Jamestown, New York. It was the Jamestown, New York facility that was the headquarters of Blackstone Cooperation that consolidated these factories in Sweden under one umbrella. There are roughly 1,000 TitanX employees worldwide.
