Most Irish early-stage failures are not market failures. They are structural failures inside the founding team — equity assumed but never agreed, exits never discussed, governance left to goodwill. This report aggregates what PartnerReady sees in the diagnostic, what published research consistently shows, and what Irish corporate solicitors describe as the single most common preventable causes of co-founder breakdown.
Most common founder blind spots
- Verbal equity agreements treated as binding by one founder, optional by the other
- No vesting, no cliff, no leaver mechanics on day one
- 50/50 ownership with no chair, casting vote or reserved matters list
- IP and pre-incorporation work that has never been formally assigned to the company
- Salary expectations diverging by an order of magnitude with no written reference point
- Exit horizon mismatch — venture-scale vs lifestyle — never named between founders
Six categories of founder risk — frequency of meaningful misalignment
Founder compatibility trends
When co-founders complete the PartnerReady diagnostic independently, the most predictive signal of future conflict is not the score itself — it is the divergence between the two answers. Teams whose answers diverge by more than 30% in three or more of the six categories show the strongest correlation with later structural disputes.

Equity structure trends in Ireland
How Irish two-founder teams actually split equity
PR| Split | Share of teams | Vesting in place |
|---|---|---|
| 50 / 50 | ≈ 71% | ≈ 24% |
| 60 / 40 | ≈ 14% | ≈ 41% |
| 70 / 30 | ≈ 8% | ≈ 52% |
| Other (incl. founder pools) | ≈ 7% | ≈ 60% |
Founder communication gaps
Across the diagnostic, the single most common written agreement between Irish co-founders is — nothing. Term sheets, founders' agreements and shareholders' agreements are routinely deferred until 'after we have something to protect', which in practice means after the relationship has already absorbed eighteen months of unspoken assumptions.
Exit-planning trends
Have you and your co-founder ever discussed exit terms?
Governance preparedness
- ≈ 76% of two-founder Irish teams have no documented reserved matters list (PR)
- ≈ 81% of 50/50 teams have no tie-break mechanism (PR)
- ≈ 22% of teams have a written founders' agreement before incorporation (PR)
- ≈ 18% of teams have ever pressure-tested a 'co-founder leaves in year two' scenario (PR)
Founder archetype breakdowns
Across PartnerReady completions, four founder archetypes recur: the Builder (technical-led, equity-light on intent), the Operator (commercial-led, equity-aware), the Visionary (high-ambition, low-structure), and the Steward (long-horizon, governance-instinctive). The most resilient teams pair complementary archetypes; the most dispute-prone pair two Visionaries with no Steward.
Common dispute triggers
- Asymmetric commitment surfacing during a fundraise
- Salary increase requested by the full-time founder
- Unsolicited acquisition offer revealing exit horizon mismatch
- Hiring decision blocked by deadlock
- New investor requiring governance the founders never agreed
What founders consistently underestimate
Solicitor observations
By the time a founder dispute reaches my office it almost always presents as a drafting question. Underneath it is six months of conversations that should have happened before incorporation.
Accelerator observations
We can predict the cohort companies most likely to break apart by the end of week one. The signals are always founder-level, never market-level.

Frequently asked questions
How was this benchmark report compiled?+
It combines anonymised observations from PartnerReady diagnostic completions by Irish founders, published research on founder behaviour and shareholder disputes, and structured interviews with Irish corporate solicitors and accelerator directors. Sources are tagged inline.
Are these statistics scientifically representative?+
PartnerReady platform observations represent the population of founders who choose to complete the diagnostic, which skews toward more deliberate, pre-incorporation teams. Where we cite directional benchmarks rather than measured data, we label them as estimates.
Can I cite these statistics?+
