The Kroll Story

Kroll was founded in 1972 by Jules B. Kroll as a consultant to corporate purchasing departments. The company focused on helping clients improve operations by uncovering kickbacks, fraud and other forms of corruption.

In the 1980s, Kroll became known as “Wall Street’s private eye” as a result of its high-profile investigative due diligence work in the financial sector. The company later gained worldwide renown for its success in searching for assets hidden by Jean-Claude Duvalier, Ferdinand and Imelda Marcos, and Saddam Hussein.

In December 1997, Kroll merged with armored car manufacturer O’Gara-Hess & Eisenhardt and became The Kroll-O’Gara Company, a public company listed on NASDAQ.



In the late 1990s and early-mid 2000s, the company embarked on a series of acquisitions that expanded its areas of expertise and suite of services. Among them was Kroll Ontrack, a leading provider of information management, data recovery, and legal technologies products and services.

In August 2001, following the sale of the O’Gara businesses, the company’s legal name was changed to Kroll Inc. and its ticker symbol became “KROL.” In July 2004, Kroll was acquired by professional services firm Marsh & McLennan Companies, Inc.

Kroll is currently owned by Corporate Risk Holdings, LLC, which is also the parent company of two separately-managed information service businesses: HireRight and Kroll Ontrack. The majority shareholders of Corporate Risk Holdings are certain investment funds, including funds managed by Third Avenue Management LLC, Litespeed Management LLC and Mudrick Capital Management LP.
