## Questions

### Who runs investment decisions at D1 Capital Partners?

Daniel Sundheim is the founder and chief investment officer, holding final authority over the portfolio. Sundheim spent over a decade at Viking Global Investors, serving as CIO before departing in 2018. The senior investment team includes former Viking colleagues and analysts recruited from other Tiger-aligned funds, but the firm's investment process is centralized around Sundheim's macro and idea-generation framework.

### Is D1 Capital Partners a hedge fund, a venture firm, or something else?

D1 operates a hybrid structure. Roughly half of the firm's capital is deployed in a concentrated long/short public-equity book, while the remainder funds private, growth-stage companies. This dual mandate is unusual — few Tiger Cub firms run both deeply concentrated public portfolios and $100M+ private rounds under one roof. The firm is structured as a private investment partnership, not a multi-vehicle platform.

### What check size does D1 typically write in private rounds?

D1's private investments often fall in the $100M to $250M range, with the firm leading or co-leading late-stage and pre-IPO rounds. In 2020, D1 co-led a $200M round in Instacart that valued the company at $17.7B (per The Wall Street Journal, 2020). The firm's scale allows it to act as a single counterparty for growth companies seeking concentrated capital without syndicate complexity.

### How does D1 source its private deal flow?

Sundheim's network — built over two decades at Viking and through the extended Tiger Cub ecosystem — is the primary sourcing mechanism. D1 competes with Sequoia, a16z, and Tiger Global for late-stage allocations, often winning mandates by offering larger, faster, and less dilutive single-investor checks. The firm does not operate a formal venture-studio or entrepreneur-in-residence program.

### Does D1 Capital Partners manage capital for retail investors?

No. D1 is structured exclusively for institutional limited partners, including university endowments, sovereign wealth funds, charitable foundations, and family offices. The firm has never offered a registered liquid vehicle, ETF, or interval fund, and its private-side allocations are inaccessible to accredited retail investors.
