Clarity in Complexity
Decima is a Geneva-based, woman-led private investigation firm. We conduct targeted investigations to obtain reliable, verifiable information within the legal framework of Swiss law. Our expertise is built on two investigative pillars: Open-Source Intelligence (OSINT) and Professional Surveillance.
While we are a Geneva licensed company, our international network of trusted investigators allows us to conduct or support cases across Switzerland and abroad with the same standards of discretion and legality. We work with corporate clients, law firms, and private individuals, with a commitment to discretion, accuracy, and legality.
