Cosimo Bisiach

The Path

Leadership is the throughline in the career of Cosimo Bisiach. He served as chief executive officer at Julius Baer Sim, then as chief executive officer at Alha Sim, and later as chief executive officer at Etra Sim. Each role required the same core skills: judgment under pressure, clear decisions, and the ability to carry responsibility without excess. Since 2013, that discipline has also been present in his work as senior private banker of BSI, where trust and discretion are part of the daily grammar. Alongside that position, his role as manager of Podere Marella brings his attention to an estate where land and identity are held together through practical work.

In Their Words “We also have the Trebbiano Spoletino grape, of which I am very proud because it very well represents the value of the territory and is a rare grape with excellent potential.” The statement is direct, and its terms are practical: pride, territory, rarity, potential.
