Many founders assume selection decisions are purely about quality. In reality, programs also optimize for cohort composition. This means selection is partly comparative and partly constrained.
What cohort composition usually means
- stage balance (idea, MVP, early traction)
- sector balance (not all startups in the same vertical)
- geography or eligibility constraints
- team diversity and complementary perspectives
Why it affects outcomes
If a program already has many startups in one segment, additional startups in that segment face stronger competition, even if they are strong individually.
Conclusion
Cohort composition is one reason good startups are rejected. Founders can improve outcomes by applying to programs where their segment is a clear fit and not overcrowded.
