In 1908 Anttila opened a shop in Helsinki, where he worked as a tailor. In 1932 he founded Anttilan Pukimo OY (later Kalle Anttila OY), a company producing work outfits. His son, also Kalle Anttila, later took over his father's business and founded the Anttila department store chain that now operates in Finland, Estonia and Latvia.
