A random walk down Sandhill Road

What if startup success might be best modeled and even navigated if it were imagined to be akin to a random walk down Sandhill Road? This question is the one that has recaptured my interest lately.

Simply stated, a random walk is a process that can be understood as a series of steps or stages, wherein each stage or step can be described according to some probabilistic set of outcomes (e.g., a coin toss, or a normal distribution). One of the classic examples of a random walk involves mapping the circuitous walk home of an individual who has had too much alcohol. At any corner on their walk home, this inebriated individual might turn left or right, go forward or turn back. While a map of this drunken walk betrays the underlying randomness of the clouded mind, the probability that the individual will make it home is actually pretty good — even when each decision at each corner is understood as simply a 1 in 4 chance of heading in the right direction.

If startup success were a random walk, we might find that attempts to predict success in this market would be foiled. Investment returns would be highly volatile, with low success rates but (potentially) very high returns. Investors in this sort of market would be very likely to embed “options” and other downside protections into their deal terms (e.g., liquidation preferences, follow-ons, anti-dilution, etc.).

Furthermore, and from a sociological perspective, actors in the market would be very likely to imitate the behaviors and characteristics of successful individuals (e.g., hoodies), given the ideal attributes of success would be hard to predict. For example, since Google instituted a 20% rule for employee projects, other firms would emulate this rule just in case it had something to do with Google’s success.

Evidence for random walk: present.

By and large, we tend to associate startup success with some indispensable personality trait (e.g., gambler, gunslinger, genius, or guru, according to my research), defendable market position, inimitable technology, or simply dumb luck. In this context, asserting that startup success is a function of something “random,” is largely interpreted to mean that all of those other factors are trumped by the last … dumb luck.

In truth, however, each of these factors — whether realistic or foolhardy — could play a role in navigating a random walk. I don’t translate “random” to mean that survival is based purely upon dumb luck. Instead, I tend to see randomness, when affiliated with risk, as a phenomenon that can be navigated and managed through a range of strategies.

From this random walk perspective, a phenomenon that may be random, at its core, can be managed successfully through a portfolio of options and other strategies that accomplish two interconnected goals: (1) limiting exposure to negative outcomes (aka, downside), while  (2) opening if not increasing exposure to positive outcomes (aka, upside). My word for this portfolio of strategies is “enterprising.”

For example, the premise of affordable loss emerging from the effectuation school in entrepreneurship research can be seen as an effort to manage downside risk in a random walk; never bet more than you are willing or able to lose. This rule limits downside risk by simply limiting the size of the investment. Affordable loss may be a “weak” strategy, however, since it likely limits both upside and downside by constraining the entire investment amount. Other strategies may be “stronger.”

Importantly, the odds of success are not really changed with these strategies, all other factors held equal. Instead, the firm’s exposure to both desirable and undesirable outcomes is altered. This difference is important. We may not really change the probability of survival in a set of firms, all in the same market, all with the same initial investment, etc.

However, we would see that the payoff profile of the more enterprising firms — those that manage risk in this asymmetrical manner — would be quite different from the payoff profile of the less enterprising firms.
