## Questions

### Who runs investment decisions at Light Street Capital?

Glen Kacher is the firm's sole founder, president, and chief investment officer. He built his career inside the Tiger Cub network, serving as managing director at Viking Global and co-founding Deep Current before launching Light Street in 2010. All portfolio decisions — public and private — flow through Kacher, with support from a small investment team. There is no investment committee override; the book reflects individual conviction.

### Is Light Street a hedge fund, a venture firm, or a crossover vehicle?

Light Street operates as a crossover investment manager, running a long-short public equity fund alongside a private growth-investing allocation. The firm participates in late-stage venture rounds for companies it knows through the public-equity diligence process. This structure allows it to hold positions from pre-IPO rounds through post-listing without forced asset-class rebalancing.

### What was Light Street's reported performance during the pandemic-era tech rally?

The Wall Street Journal reported in January 2021 that Light Street's flagship long-short fund returned roughly 59% net of fees in 2020, making it one of the year's top-performing hedge funds. Performance was driven by concentrated bets in technology and consumer internet names that benefited from digital acceleration. The firm has not publicly disclosed subsequent full-year figures.

### How does Light Street's Tiger Cub lineage shape its investment approach?

Kacher trained at firms where the benchmark was not tracking a broad index but building high-conviction bets through primary research. The Tiger Cub model emphasizes deep fundamental diligence, long holding periods, and concentrated portfolios. Light Street applies that framework to both public stocks and private late-stage rounds, refusing to add a name unless the team has met management multiple times and stress-tested the competitive moat.
