The Solo Founder Problem Isn't What You Think

A study published this week in the Strategic Management Journal found that solo founders with broad and deep experience perform nearly as well as co-founded teams, and the conversation that followed mostly confirmed what makes the question so dangerous in the first place.

Founders read the finding and heard permission. They catalogued their own T-shaped credentials, noted the cautionary reference to OceanGate, nodded at the Bezos example, and filed the research under "validation that going it alone can work." That is a reasonable reading of the data. It is also a way of asking the wrong question entirely.

The study compares solo founders to co-founded teams and measures exit outcomes. What it names as the solo founder's core disadvantages are instructive: limited networks, reduced legitimacy with investors, no mechanism for internal oversight, and a narrower knowledge base when the founder's depth doesn't extend to adjacent functions. These are real costs, well documented, and the researchers are correct that T-shaped expertise partially offsets them. What neither the study nor the coverage examines is the more consequential question, which is whether those gaps ever actually get filled, and through what mechanism.

The Disadvantage Is Not a Co-Founder Problem

Every disadvantage the study names for solo founders is a partnership infrastructure problem. Networks come from relationships, specifically the kind of deliberate, structured relationships that generate warm introductions, referral pipelines, and credibility transfer. Legitimacy signals come from who you are associated with, who vouches for you, and what kind of operators are willing to stake their own reputation on your direction. Oversight comes from having people in your orbit whose interests are aligned enough to tell you what you do not want to hear. Knowledge breadth comes from proximity to operators who have solved problems you have not yet encountered.

A co-founder addresses all of this through a single equity-diluting, legally complicated, emotionally loaded structure. It is a bundled solution to a set of problems that can be solved individually, more deliberately, and with far less exposure. The research frames the choice as solo founding versus team founding because that is what the data allows. But the founders who read it as a binary are making the same structural mistake as the ones who hire a head of sales and call it a revenue strategy.

The real decision is not whether to add a co-founder. The real decision is whether you are building the infrastructure that compensates for operating alone, or whether you are relying on your own depth to cover every gap indefinitely, which is a bet that gets more expensive the further into scale you take it.

What the Solo Founder With T-Shaped Skills Actually Needs

The founder the study holds up as the viable solo case, the one with depth in one function and genuine breadth across adjacent ones, is the founder most likely to underestimate the partnership gap. She has enough knowledge to make informed decisions across the business, enough confidence to move without consensus, and enough past experience to feel like she has seen the failure modes before. The dangerous version of this profile is not the founder who lacks experience. It is the founder whose experience is real enough that she reads her own competence as sufficient, and never builds the external relationships that would surface the things she does not know she does not know.

The most consistent pattern in founders who stall between early traction and scale is not a product failure or a hiring failure. It is a pipeline failure that traces back to a partner relationship that was never built, a category of distribution that was never accessed, a network that was never deliberately cultivated because the founder believed her own reputation would eventually pull the right people in. Competence and pipeline are not the same asset. The founder who can build the product, manage the team, and present compellingly to investors is still starting from zero every time she tries to grow through a channel she does not own and has not negotiated access to.

The study identifies networks as one of the things a co-founder brings. What it does not say is that network is the compounding asset in the model, the one where every additional connection changes the value of every prior connection, and where the cost of starting late is not linear. A founder who begins building partner relationships at Series A is not six months behind the founder who started at incorporation. She is operating on a fundamentally different curve, because the relationships that produce warm introductions in year three are almost always the ones that were tested in year one, when neither party had anything to gain from being generous.

What the Research Is Actually Telling You

The study did not prove that solo founders do not need partners. It proved that experience can compensate for the absence of one specific, equity-bearing partner. That is a narrower finding than most of the commentary has treated it as, and the distinction matters because the founders most likely to misread it are the ones who already have the credentials that make solo founding viable on paper.

T-shaped expertise helps you make better unilateral decisions. It does not build your distribution. It does not expand your network. It does not give you access to the rooms where deals are structured before they are announced. It does not generate the kind of inbound that comes from an ecosystem of partners who have skin in your success and relationships that predate your current round of outreach. Those are partnership problems, and they do not resolve themselves through individual competence, no matter how well-earned that competence is.

The founders who scale well past the point where solo founding becomes structurally limiting are almost always the ones who treated partnership as a function of the business, the same way they treated hiring or product or finance, building deliberate structures around it, maintaining relationships before they needed them, and measuring pipeline the way they measured revenue. Platforms like onSpark exist because that function is hard to systematize from scratch when you are also running everything else, and the founders who try to build it informally tend to discover the gap at exactly the moment they can least afford to.

The research is worth reading. The conclusion that matters is not that solo founding can work. It is that the conditions under which solo founding works are more specific than most founders who want to believe them will allow themselves to see clearly.
