IGI (Investigative Group International, Inc.) is a preeminent corporate investigations and risk advisory firm comprised of former prosecutors, forensic accountants, researchers, investigators, and analysts who come from federal and state law enforcement, the White House, intelligence agencies, finance, and journalism.

IGI collects timely, accurate intelligence and conducts confidential fact-finding investigations with the utmost discretion in complex cases worldwide for clients including law firms, corporations, investment banks, hedge funds, universities, public agencies, and prominent individuals. Our experience with high-profile cases is matched by our ability to handle sensitive matters.

For over 30 years, we have worked with clients to make effective use of the information we gather—including by building a case against an opponent for referral to government regulators or law enforcement; marshalling facts to support the client’s narrative in crisis situations; and developing information for dissemination to news media. 

IGI has been described as “Washington’s premiere investigative firm” by The National Journal, as “the gold standard in private financial detection” by The New York Times, and as “legendary for its “opposition research” probes - political or otherwise - that expose unseen connections” by The Washington Post.
