description: Susquehanna International Group (SIG) is a privately held global quantitative trading firm founded in 1987 by
  a group of college friends who began trading on the Philadelphia Stock Exchange, leveraging quantitative skills and poker-derived
  decision science. Headquartered in Bala Cynwyd, Pennsylvania, the firm employs more than 3,500 people across 17+ offices
  worldwide and operates as one of the largest options market makers globally. SIG's businesses span Quantitative Trading,
  Predictions, Institutional Sales, Growth Equity (Susquehanna Growth Equity / SGE), Sustainable Investments, Asia-focused
  Venture Capital (notably an early and large stake in ByteDance), and the River's Edge promotional arm. SIG does not operate
  a public developer portal, expose external trading APIs, or publish open-source repositories under a public GitHub organization;
  all technology is internal to the trading and quantitative research platform. Public surface is limited to sig.com (company
  / careers / insights), the SGE site, and corporate communications.
