The Biggest Risk Isn’t the Market
Technology, the market, and funding tend to top the lists of reasons for startup failure. But research by Noam Wasserman, who studied more than 10,000 founders at Harvard Business School, paints a different picture: the vast majority of early-stage startup failures stem from founder team dynamics (The Founder’s Dilemmas, 2012).
While market research is conducted, financial models are prepared, and technical infrastructure is set up, the relationships among founders themselves are often not addressed with the same level of care.
Things Not Discussed at the Start
Wasserman’s finding: Most conflicts stem not from personality clashes, but from expectations that weren’t clarified from the outset.
What conversations are often left unaddressed?
The logic behind equity distribution: A 50-50 split seems fair at the outset. But what if one founder works full-time while the other works part-time, or if one wants to step back after two years? When these scenarios aren’t discussed upfront, subsequent disagreements become personal.
Boundaries of decision-making authority: Who has the final say on which issues? What does “we make decisions together” actually mean in practice? This ambiguity turns into friction as the company grows.
Exit scenarios: What happens when someone wants to leave? This conversation might feel like a bad omen. But more than half of founders leave within five years.
Work expectations: How many hours, under what conditions, and until when? “Working like an entrepreneur” means very different things to different people.
Growth Disagreement
Ben Horowitz, in his book The Hard Thing About Hard Things (2014), identifies another common source of tension: founders disagree on what it means to scale the company.
One wants to “preserve the vision,” while the other wants to “do whatever it takes to scale.” This isn’t a matter of debate; it’s a fundamental difference in values. And when this difference comes to the surface, every decision turns into a battlefield.
Patrick Lencioni’s Trust Framework
In the model presented in The Five Dysfunctions of a Team (2002), a lack of trust is the most fundamental dysfunction. This is particularly sensitive among co-founders: underlying the conflict is often the question, “Do they really trust me?”
Small signals quietly erode trust: decisions made without consultation, delays in sharing information, things told to one person but not the other. When these signals aren’t addressed before they accumulate, they eventually surface as a major explosion.
After the Conflict Begins
Early intervention means starting a conversation before the conflict deepens: “I sense some tension here. Can we talk about this?” This is a difficult sentence to say, but it’s one of the phrases that can save a co-founder relationship.
External mediation, a coach, or an experienced consultant provides an objective ground for this process. This is because defensiveness often kicks in when the two founders speak directly to each other.

Cevvela’s Perspective
- Co-founder conflicts stem not from personality clashes, but from conversations that weren’t had at the outset (Wasserman, 2012).
- Equity structure, decision-making authority, exit scenarios, and work expectations—addressing these four issues early on can prevent major conflicts.
- Differences in the understanding of growth create a fundamental clash of values; every decision turns into a battlefield.
- Trust erodes silently; noticing small signs early on creates space for repair (Lencioni, 2002).
- Coaching can be used in this process to initiate conversations that were not had at the outset on safe ground or to shift the conflict into a healing process.
