Investment Philosophy Inspired By Legendary Value Investors
- Prospector Partners began in 1997 when John Gillespie reunited with his mentor, Jack Byrne, who became a founding investor of Prospector. Byrne was the legendary CEO of GEICO (acquired by Berkshire Hathaway), Fireman’s Fund (acquired by AIG), and White Mountains Insurance Group. Warren Buffett referred to Jack Byrne as “the Babe Ruth of insurance.”
- The portfolio management team at Prospector played prominent roles in managing investments for White Mountains from the late 1990’s until 2015. Much of the investment philosophy at Prospector, approaching value investing from a balance sheet and credit perspective, is inspired by the investing principles of Jack Byrne and Warren Buffett.
