### Approach
D1 Capital employs a fundamental, research-intensive investment strategy with a medium to long-term horizon. The firm operates as a crossover manager, deploying capital in both public and private markets. Its public strategy involves long/short equity investing, while its private strategy focuses on later-stage, non-control minority stakes in growth companies.

### History
D1 Capital Partners was founded in July 2018 by Daniel Sundheim, a former Chief Investment Officer at Viking Global Investors. The firm experienced rapid growth in its early years but faced significant challenges, including major losses during the 2021 GameStop short squeeze and the 2022 market downturn. Following these setbacks, the firm implemented strategic changes in June 2022 to reduce risk, increase diversification, and adjust its investment coverage, leading to a strong performance recovery.
