Pop culture frequently glorifies the lone genius who builds a massive empire from a garage. However, recent academic research suggests a different reality for most startups. Conventional wisdom in the startup ecosystem dictates that entrepreneurs need co-founders to succeed. A new study from the University of Kansas highlights why building a company with a partner remains the standard approach in USA entrepreneurship, emphasizing the distinct tactical advantages that multiple founders bring to a new venture.
Co-founders provide immediate access to a broader network of contacts, which is critical in the early stages of business development. Much of entrepreneurship relies on social capital—knowing the right investors, mentors, and early adopters. When you have a co-founder, you essentially double your immediate network. Beyond just connections, co-founders bring diverse skill sets and specialized expertise to the table. If one founder excels in software engineering, the other might possess critical skills in marketing or financial operations. This combination allows the startup to tackle complex problems more effectively than a single individual could manage alone.
Additionally, having a co-founder acts as a powerful signal to the outside world. Investors and early customers often look at a founding team as a measure of a startup’s viability. A solitary founder can sometimes trigger unintended questions: Is this person difficult to work with? Is the idea not strong enough to attract a partner? By choosing to work with co-founders, entrepreneurs can bypass these initial doubts and present a unified, capable front to the market.

While the benefits of partnerships are clear, some founders still choose to go it alone. Understanding the inherent risks of solo founding is crucial for anyone considering this path. The most prominent danger is the complete lack of oversight and checks and balances. When a single person holds all decision-making power, there is no internal mechanism to challenge bad ideas or prevent reckless behavior.
Todd Hall, an assistant professor of business at the University of Kansas, points to the tragic example of OceanGate CEO Stockton Rush as a stark warning. Rush operated his deep-sea exploration company as a solo decision-maker, ignoring the concerns of industry experts and internal staff. The resulting implosion of the Titan submersible in 2023, which killed Rush and all passengers, illustrates the catastrophic potential of unchecked solo leadership. In high-stakes environments, the absence of a co-founder to say “stop” can lead to fatal flaws in product development and operational safety.
Beyond extreme safety risks, solo founders face everyday business vulnerabilities. Without a partner to share the workload, solo founders are highly susceptible to burnout. They must independently navigate the complexities of product development, legal compliance, fundraising, and hiring. This overwhelming workload can lead to critical mistakes or missed opportunities that a well-rounded team would easily catch.
Despite the significant risks, the University of Kansas study does not dismiss solo founding entirely. There are specific, measurable scenarios where building a company alone provides distinct competitive advantages. The most notable benefit is speed. Co-founding teams must debate, compromise, and align their visions before taking action. A solo founder can bypass this bureaucracy entirely, making unilateral decisions and executing their vision rapidly.
This ability to impose a clear, singular vision on a company can be a massive asset, provided the founder’s direction is correct. Decisions regarding product features, hiring choices, and market positioning can be made in hours rather than weeks. In fast-moving markets, this agility can be the difference between capturing market share and falling behind. Furthermore, avoiding the interpersonal conflict that inevitably arises between co-founders allows the solo entrepreneur to maintain complete focus on the product and the customer.
Consider the example of Jeff Bezos and Amazon. Bezos started the company alone, driven by a highly focused, albeit initially unglamorous, vision to sell books online. Because he did not have to negotiate with a co-founder, he was able to consistently reinvest any profits back into the company to fuel aggressive growth. His absolute control allowed him to execute a long-term strategy that ultimately changed global retail.

If an entrepreneur decides to pursue solo founding, the University of Kansas research identifies a specific profile that mitigates the typical disadvantages: the possession of T-shaped skills. In the context of USA entrepreneurship, T-shaped expertise means having deep, specialized knowledge in one specific area, combined with a broad, functional understanding of many other disciplines.
A successful solo founder cannot afford to be purely a technical expert or solely a business strategist. They must span both domains. For example, a solo founder might have deep expertise in artificial intelligence programming, but they also need a working knowledge of financial modeling, user experience design, and B2B sales. Hall notes that individuals who transition between distinct roles—such as an engineering major who later becomes a project manager—naturally develop this broad base of knowledge while maintaining their technical depth.
Acquiring T-shaped skills requires intentional effort. Aspiring solo founders should actively seek cross-functional experiences. This might involve taking on stretch assignments at a current job, pursuing formal education that bridges technical and business gaps, or independently studying adjacent fields. The goal is to build a personal skill set that mimics the diverse capabilities a co-founding team would otherwise provide. Without this broad foundation, a solo founder will inevitably hit a wall when the business requires expertise outside their narrow specialization.
The conclusions drawn by the University of Kansas are not based on anecdotal evidence alone. To rigorously test the viability of solo founding versus utilizing co-founders, the researchers conducted two comprehensive studies using highly respected industry data. The first study utilized data from Y Combinator, one of the most prestigious and selective startup accelerator programs in the world. The second study leveraged large-scale data from Crunchbase, the primary database for global startup information.
By mapping LinkedIn profiles to the founders listed in these databases, the researchers could accurately separate solo founders from co-founding teams and track their long-term outcomes. Success in these studies was strictly defined as achieving a successful exit, either through an initial public offering (IPO) or an acquisition. This data-driven approach confirmed that while co-founders generally provide a structural advantage, solo founders who possess broad and deep experience can achieve comparable levels of startup success.

Deciding between solo founding and seeking co-founders is one of the most critical choices an entrepreneur will make. The research from the University of Kansas provides a clear framework for making this decision. You must objectively evaluate your own experience level, your skill set, and your personality.
If you possess T-shaped expertise, have a clear and tested vision, and have the strong personality required to enforce your decisions without second-guessing, solo founding may be a viable path for you. However, if you lack experience in key business areas, or if you recognize that you benefit from collaborative brainstorming and shared responsibility, you should actively seek out co-founders.
As Todd Hall notes, individuals who can successfully solo found are the exception, not the rule. For the vast majority of aspiring entrepreneurs, bringing on a partner provides the necessary safety nets, diverse skills, and network connections required to navigate the difficult early stages of a startup. Evaluate your weaknesses honestly, and build your founding team—whether that team consists of one person or multiple—to maximize your chances of success in the competitive landscape of USA entrepreneurship.
