Guy Carpenter's breakthrough idea—using data insights to drive growth—still guides our business today.
At the beginning of the 20th century, the insurability of harvested cotton was vital to the economic stability of the American South. As a young man in the cotton insurance business, Guy Carpenter discovered that the industry was haphazard and reactive. A year of big losses pushed the next year’s premiums too high, while a lucky year sent prices down, often exposing insurers and reinsurers to more risk than they had anticipated.
In 1923, Carpenter met with cotton insurance brokers Henry W. Marsh and Donald R. McLennan during a transatlantic crossing. Guy Carpenter & Company would become part of Marsh McLennan and take the nascent science of analytics far beyond cotton, laying a foundation of quantitative precision that continues to this day. This partnership would also give Guy Carpenter clients the advantage of being able to tap into the financial strengths of the Marsh McLennan enterprise.
The insight that data—the more, the better—could help clients anticipate perils and measure risks put Guy Carpenter on a trajectory that is still transforming the industry.
Today, Guy Carpenter is a leader in the reinsurance broking industry by bringing together unmatched data insights with bespoke solutions to help clients turn risk into profitable growth.
