Venture capital presents a compelling asset class characterized by the investment in companies that may initially operate at a loss but exhibit significant growth potential. The fundamental premise lies in the application of the "power law," wherein the expectation is that a select few investments within a portfolio will yield returns substantial enough to either cover the entire fund or contribute significantly to its overall performance. Notably, the efficacy of the power law tends to be more pronounced in smaller funds compared to their larger counterparts. Let's see how.

In the context of venture capital, the power law concept entails that, although a typical fund comprises a diversified portfolio of approximately 20 companies, the anticipation is that each of these entities possesses the latent capacity to generate returns equivalent to, or surpassing, the entire fund's value. While this aspiration is not universally realized, it forms the basis of the investment decision-making process for venture capitalists.

The distribution of successes and failures in venture capital portfolios is typically uneven. A handful of companies may deliver returns of 10%, 20%, or even 100% of the fund, while others may only recoup their initial costs or fail to do so altogether. The implications of this dynamic become more apparent when considering the size of the fund.

Assuming that five companies, constituting a quarter of the portfolio, are instrumental in driving the total fund return, the challenge becomes evident. Analyzing the scenario further with basic venture capital calculations, where the average stake at exit is 6%, reveals that scaling up the fund size amplifies the difficulty of achieving proportional returns. For instance, a $100 million fund necessitates a total portfolio valuation of $3.34 billion for success, making it a more formidable task than its $50 million counterpart.

Quick math:

$50m fund, 6% average exit stake in companies at exit:
For 2x fund return ($100m), portfolio requires aggregate $1.67bn value.
For 3x the fund ($150m), portfolio requires aggregate $ 2.5bn value.
$100m fund, 6% average stake in companies at exit,
For 2x fund return, portfolio requires $3.34bn value.
for 3x fund return, portfolio requires $5bn value.

When you further take into account that approximately 5 companies have to bring all or the lion's share of the value, the challenge is higher.

There are of course outliers to the above math. However, the mathematical analysis clearly underscores the relative ease of scaling smaller funds compared to their larger counterparts, emphasizing the constraint imposed by the limited pool of opportunities for substantial exits in larger funds.

Having delineated the mathematical dynamics, the subsequent pivotal challenge for venture capitalists becomes securing "access to winning companies". Delving into this aspect warrants a separate exploration.
