Social Capital Theory and Entrepreneurship

Why do some people seem to have access to better opportunities than others? The answer often lies in their network—but not the part of the network you might expect.

The Weak Ties Theory was put forth by sociologist Mark Granovetter in 1969 (published widely in 1973). In a groundbreaking study of job seekers, he found that 75% of people found their jobs through acquaintances, not close friends. Surprisingly, the rate was even higher for high-income earners.

The core insight of the theory is that "Weak Ties" are paradoxically more powerful than "Strong Ties" when it comes to gathering new information.

Strong Ties (Close Circle): These are roommates, nuclear family, and best friends. While they offer trust, they provide very little new information. Because you move in the same circles, you already know what they know. It is an echo chamber.
Weak Ties (Acquaintances): These are colleagues, friends of friends, or people you see rarely. They act as bridges to disparate networks that you do not belong to. They are the conduits for novel information (new jobs, new technologies, new market gaps).

What is Social Capital?

Social capital is loosely defined as the value of a venture founder’s network resources.

Networks may act as substitutes for investment capital. Private information flows over networks that can only be accessed through social interactions. An entrepreneur’s ability to recognize opportunities is largely related to their ability to access private information within these webs.

Social ties that bridge unconnected social networks are called bridging ties, and these are particularly useful for finding valuable opportunities.

The Entrepreneur as a "Broker"

Entrepreneurship is embedded in networks of enduring social relations (Walker et al., 1997). A structural hole is formed by a lack of social connections between large social networks (Burt, 1992). It is not the number of ties that matters, but how non-redundant they are.

If an individual connects two social groups that are otherwise unconnected, that position yields a better opportunity (brokerage).
If there are several links needed to connect two networks together, then being the sole direct link yields significant power and advantage.

Individuals who have many ties to diverse networks are able to bridge structural holes. A structural hole is a gap between two groups that do not talk to each other (e.g., software engineers and biologists). An entrepreneur who acts as a bridge between these groups occupies a strategic position. They can:

Arbitrage Information: Pass a solution from Group A to Group B (where it is unknown).
Facilitate Transactions: Connect a supplier with a client and collect a finder's fee or commission.
Drive Innovation: Combine ideas from disparate industries to create something new.

Empirical Evidence

Empirical studies examine whether individuals with more structurally diverse networks are more likely to encounter opportunities that can be seized through new venture creation (Greve and Salaff, 2003).

Entrepreneurs with structurally diverse networks may benefit from:

Better access to financial capital
Access to tacit knowledge and talented human resources
Increased influence and legitimacy with stakeholders

Controversy: The "Old Boys' Club"

This theory argues that success isn't about what you know, but who you know (your network).
The Controversy: It admits that meritocracy is a myth. If "Social Capital" is the primary driver of success, then entrepreneurship is simply a way for existing elites to pass wealth back and forth, excluding those without the "right" connections.

Some regard the practical application of weak ties theory as potentially unethical. It suggests actively cultivating shallow relationships for transactional gain ("divide and conquer"). This more calculated approach to human connection shares characteristics with the Machiavellian Theory of Entrepreneurship, implying that successful founders may view people as resources rather than friends.
