Business partnerships drive economic growth. But the statistics are alarming: according to a Harvard Business School study, most startups don't fail because of the idea or market — they fail because of the founding team.

What the Research Says

The CB Insights study (2021) analyzed over 100 startup failures and identified "not the right team" as the 3rd most frequent cause of failure — ahead of product or technical problems.

Professor Noam Wasserman at Harvard Business School, in his book "The Founder's Dilemmas" (2012, Princeton University Press), studied over 10,000 founders and found that:

65% of high-potential startups fail due to co-founder conflicts
Founders who don't proactively discuss roles, equity, and vision are 2.5x more likely to be unhappy
Friendship-based partnerships (without objective evaluation) have the highest failure risk

McKinsey Research on Joint Ventures

A McKinsey & Company study (Bamford, Ernst & Fubini, 2004), published in the Harvard Business Review, showed equally concerning results:

Most frequent causes: strategic misalignment, lack of clear governance, and cultural differences. But partnerships with structured pre-deal evaluations have 30% higher success rates.

What Dimensions Actually Matter

Research converges on 6 essential compatibility dimensions:

The 6 compatibility dimensions: Values, Goals, Decisions, Leadership, Operations, Finance — The 6 dimensions evaluated by Venn for every partnership

Values Alignment — Studies by Meglino & Ravlin (1998) show that value alignment is one of the strongest predictors of satisfaction in professional relationships
Goal Alignment — Without a shared vision, the partnership becomes two separate businesses under one roof
Decision Style — Differences in speed and method of decision-making are a major source of conflicts (Eisenhardt, 1989)
Leadership Style — Leadership incompatibility leads to team confusion and operational chaos
Operational Compatibility — Incompatible processes create daily friction
Financial Resilience — Different risk tolerances are a ticking time bomb

The #1 Risk Dimension

According to research, values alignment is the only predictor that, if missing, makes partnerships practically unrecoverable — regardless of how well the other dimensions score.

Scientific Proof: Structured Evaluation Works

A randomized controlled trial (RCT) by Camuffo, Gambardella et al. (2019), published in Management Science and replicated in 2024 across 759 firms, demonstrated that:

The Strongest Study in the Field

Entrepreneurs using structured evaluation (hypothesis testing) achieve significantly better outcomes. The greatest beneficiaries are entrepreneurs with "middle" ideas — which represents the vast majority of business ideas.

The Solution: Structured Evaluation Before Commitment

The research is clear: partnerships that go through a structured evaluation process before commitment have significantly higher success rates.
