OSA International is expanding its head office in Paris, also known as OSI Europe, to 200 square meters next week, and plans to grow its personnel there to 12-15 employees before the end of the year. The office currently has five employees plus five sales persons. The move follows a 300 percent rise in turnover in the company's first year of operation in Europe. The office was first expanded last October, but at 80 square meters in size it became too small too quickly.
