Upon Jalles return to Sweden, Jalle brought back valuable industry knowledge and had become almost fluent in Italian. This enabled him to join his father in running the company and pushing Boman Trading forward.
Year by year, the business grew steadily.

In 1980, Jalle took over Boman Trading from his father, who remained active for a few more years.
Over time, Jalle and Federico from Atlantica became close friends, spending many summers together in Italy.
