## Questions

### Who runs investment decisions at SIG?

Jeff Yass and Arthur Dantchik serve as Co-Founders and Managing Directors. Steven Schuler is CEO of SIG Management, the firm's administrative entity, and Michael Blaugrund is COO. The partnership votes on major capital allocation decisions. Investment teams at Susquehanna Growth Equity and the venture arm operate semi-autonomously with oversight from the partnership.

### How does SIG source proprietary deal flow?

SGE sources deals primarily through its network of operating partners and industry executives, many of whom are former SIG employees. The firm's roots in financial technology and market structure give it unique insight into payment rails, exchanges, and financial infrastructure. SGE often takes minority stakes with board seats.

### Does SIG participate in fund commitments or only direct deals?

SIG does not commit to outside third-party funds as a traditional LP. All investing is direct, through SGE, Susquehanna Venture Capital, or the firm's internal hedge fund and trading strategies. The partnership does occasionally co-invest alongside other families or institutions in specific deals.

### What sectors does SIG explicitly avoid?

Publicly, SIG has not declared any prohibited sectors. However, SGE's known portfolio avoids early-stage biotech, hard tech, and regulated industries outside financial services. The firm is cautious on consumer-facing winners-take-most markets because of its quantitative, data-driven approach.
