Investor Jeffrey S. Yass is a founder of Susquehanna International Group (SIG) headquartered in suburban Philadelphia. SIG was established in 1987 by Yass and several of his other SUNY Binghamton pals. Yass currently serves as a managing director at the firm and also sits on the board of the Cato Institute, the D.C. based libertarian think-tank. He's been in the news having given more than $2 million to Rand Paul. Yass, a 1979 SUNY Binghampton graduate, has been obsessed with odds and probability since he was a youth— an interest which earned Yass a million dollars just a few years after graduating. It's unclear how much the SIG cofounder is currently worth and Yass flies somewhat under the radar, as does his philanthropy. He and his wife, Janine, do not yet appear to have a family foundation, but a vehicle called Choice Academics reveals the couple's philanthropic focus. According to Philly.com, Janine runs Choice Academics and tax records show that the vehicle has been used to channel modest funds to Boys' Latin Charter School of Philadelphia, a school which serves diverse youth.
