AIG (American International Group) is an insurance group in New York that works with clients in more than 200 countries. It offers property casualty insurance, risk management, and financial services, with $24 billion in net premiums written in 2024. The company has a large workforce and a strong presence in both commercial and personal insurance markets.
AIG dates back to 1919, when Cornelius Vander Starr set up American Asiatic Underwriters in Shanghai, China. The company quickly grew, with Nelle Vander Starr joining in 1923 and becoming its first woman executive. By 1926, AIG had opened its first US office in New York City which marked the start of its American story.
AIG moved its main offices to New York City in 1939 because of World War II. It opened offices in Cuba, the UK, and Australia by the late 1950s. In the 1960s, the company was incorporated in Delaware and began trading publicly, which set the stage for even more growth.
AIG made history in 1992 as the first foreign insurer licensed in China in over 40 years. The company also launched one of the first cyber security insurance programs in 1999. The firm then formed a joint venture with Tata Group in India and acquired Travel Guard.
The firm faced a major test during the 2008 financial crisis, receiving government support but repaying it by 2012. The company continued to grow when it acquired Fuji Fire and Marine in Japan and Validus Holdings, Ltd. in 2018.
In recent years, AIG became the title sponsor of the Women’s British Open and helped triple the tournament’s prize money. This highlights its commitment to equality and excellence in sports.
Today, AIG serves clients in about 190 countries and jurisdictions. The company states that it remains dedicated to creating opportunities and raising standards for clients and partners around the world

The company offered hands-on learning in areas like claims, finance, and underwriting, helping interns develop industry skills and professional networks. This program supports its long-term growth by preparing new professionals who understand its business and values.
The company also helped boost the visibility of women’s golf by serving as the title sponsor of the AIG Women’s Open.

The firm continues its focus on equality and works to lead in supporting women’s sports.

Larry Roth, chief executive of the beleaguered AIG Advisor Group, thinks that within six months, the network of broker-dealers that is home to 6,000 registered representatives and financial advisers will be “hitting on all cylinders.”
