Over 23 Years of Service


Things have to start somewhere. The inception of International Investigative Group occurred twenty-two years ago in New York, New York. Daniel Ribacoff (founder and CEO of the firm) paired his experience in both law enforcement and the diamond business to undertake investigations that pertained to robberies and fraudulent claims. From here, the IIG brand was born. The network of agents and staff employed globally continues to grow to this day. International Investigative Group has now become a global firm, offering an ever-growing amount of services to clients of all backgrounds, interests, and sectors.
