The main founder of the company was Finnish American Urho Hammer, who returned from the US to his native Finland to start automotive industry.
He returned to Finland in 1921, after which he presumably run some kind of coachbuilding activity before setting up the company Autokoritehdas, "automobile coach factory", in 1923 together with Kalle Kustaa Luoto and Kusti Jalo Hagelin.
Uotila was removed from office in December 1925 and the new manager was appointed Einar Juho Emil Rinne starting from January 1926; in the same March the company got a new chair Lars Wilhelm Åberg.
[1] After a couple of years the company suffered from lack of assets, despite a fairly good order book, and Autokoritehdas got loans from different banks to be able to run its operation.
This took place on 1 April 1931 when Åberg, Karl Arthur Nordgren and Emil Anton Winckelmann left an application to Ministry of Trade and Industry to create a new company O/Y Suomen Autoteollisuus A/B (SAT).
