What Is Venture Capital?
Venture capital is the business of investing in young, fast-growing private companies in exchange for minority equity ownership. VC firms raise funds from limited partners such as endowments and pension funds, then deploy that capital across dozens of startups, typically in technology, healthcare, and other sectors where a small company can grow into a very large one.
Unlike private equity, venture capitalists do not take control of companies and rarely use debt. They buy stakes of perhaps 10% to 25% in a funding round, take a board seat, and help the company recruit, fundraise, and scale. Rounds are labeled by stage: pre-seed and seed for the earliest companies, then Series A, B, C, and beyond as the business matures.
The Power Law of Returns
Venture returns are driven by a power law rather than by averages. In a typical portfolio, a large share of investments go to zero, many return roughly the money invested, and one or two outliers return 20x, 50x, or more. Because of this, VCs underwrite every deal asking whether it could plausibly return the entire fund, not just whether it will avoid losing money.
This dynamic shapes everything about how VCs behave: they prioritize enormous addressable markets, exceptional founders, and businesses that can compound quickly, and they accept a high failure rate as the cost of exposure to the outliers.
Example
Imagine a $200 million fund that makes 25 investments of $8 million each. Fifteen fail entirely, nine return a combined $150 million, and one early bet on a breakout company grows to a $500 million position at exit. The fund returns $650 million on $200 million, a 3.25x gross multiple, with a single company contributing more than the rest of the portfolio combined.
The GP would then earn carried interest, typically 20%, on the fund's profits, which in this case would be about $90 million before fees and expenses are factored in.
Why It Matters
Venture capital funds the companies that often become the largest in the world; Google, Amazon, and virtually every major tech company raised VC money early on. For finance careers, VC attracts people who want to work closely with founders and evaluate markets and products rather than run LBO models.
In interviews, expect questions about how VC economics differ from PE, why minority stakes and no leverage change the return profile, and how a fund can succeed even when most of its investments fail.
