Equity is the most over-discussed and under-structured decision in Irish early-stage companies. Most founders agree a split before contributions are quantified, then defer every structural protection — vesting, cliff, leaver mechanics, transfer rules — until the next investor demands them.
The reality of 50/50 splits
Equal splits are not the problem. The problem is equal splits with no governance protection, no vesting and no agreement on what happens if one founder leaves in year two.

Technical vs commercial founder allocation
Across PartnerReady completions, technical founders systematically under-claim equity at incorporation and over-claim it eighteen months later. Commercial founders show the inverse pattern. The midpoint is the sustainable split — and almost no team negotiates to it.
Vesting adoption rates
Vesting in place at incorporation
- No vesting64%
- 4yr / 1yr cliff26%
- Other vesting10%
Founder departure risk
- ≈ 64% of unstructured teams retain departing-founder equity in full (PR)
- ≈ 18% of teams have ever pressure-tested a year-two leaver scenario (PR)
- Departing-founder equity is the single most common diligence flag at the first institutional round (EST)
Equity and commitment mismatch
Investor expectations
Institutional investors in Ireland increasingly expect 4-year vesting with a 1-year cliff, founder leaver mechanics, and a clean cap-table at the seed round. Companies arriving without these face either repapering — or a re-priced round.
Common founder equity mistakes
- Splitting equity before quantifying capital, time, IP and network contributions
- Treating verbal promises as binding without any written reference
- Operating with no vesting, no cliff and no leaver mechanic
- Deferring the conversation until an investor forces it
- Assuming friendship will absorb structural ambiguity
Recommended frameworks
- Quantify all four contribution dimensions (capital, time, IP, network) before agreeing a split
- Adopt 4-year vesting with a 1-year cliff as the default, not the exception
- Document leaver mechanics for both 'good leaver' and 'bad leaver' scenarios
- Pressure-test the split against a year-two leaver scenario in writing
Questions Irish founders most often avoid
- What happens to equity if one of us leaves in year two?
- What is each of us actually contributing — in writing?
- What would we do if an unsolicited acquisition offer arrived next month?
- What is the agreed mechanism if we cannot agree on a major decision?

Frequently asked questions
Is a 50/50 split inherently bad?+
No. Equal splits between equally-committed founders are often the right answer. The risk is not the split — it is operating equally without governance protection, vesting, or leaver mechanics.
What vesting structure should Irish founders default to?+
4-year vesting with a 1-year cliff is the de facto institutional default. It is the structure most Irish seed investors will require by the next round.
When should equity be discussed?+
Before incorporation, in writing, with each founder's contribution dimensions quantified separately. The PartnerReady diagnostic is designed to force this conversation.
