Arthur Dantchik’s biography

Arthur Dantchik, born in 1957, is an American businessman and philanthropist renowned for co-founding Susquehanna International Group (SIG), a leading global quantitative trading firm. Raised in Queens, New York, he attended Bayside High School, where he befriended future business partner Jeff Yass. The duo continued their education at the State University of New York at Binghamton, sharing a room and cultivating a mutual interest in probability and strategic games.

After earning a bachelor's degree in biology from SUNY Binghamton, Dantchik pursued graduate studies in psychology at Arizona State University. However, his passion for strategic thinking led him to Las Vegas, where he and Yass applied their analytical skills to professional gambling, particularly poker, honing techniques that would later influence their trading strategies.

In 1987, alongside Yass and four other partners, Dantchik co-founded Susquehanna International Group in Bala Cynwyd, Pennsylvania. As Managing Director, he oversees global private equity and venture capital activities, commodity trading, and international operations in Dublin and Sydney.

A private individual, Dantchik is also known for his philanthropic endeavors through the CLAWS Foundation, supporting libertarian causes in the U.S. and Israel, as well as local initiatives in Philadelphia.
