The VC diligence questions about your cofounder relationship cover four things: who decides what, how equity and vesting work, how you handle disagreement, and whether your references tell the same story. Investors ask because a team that cannot settle a disagreement now will struggle under the pressure money brings. Prepare these answers together before the partner meeting.
Why do investors question the cofounder relationship?
Because a strong product with a shaky partnership is still a bad bet. The pitch shows the company as one voice. Diligence is where the investor looks at the people behind it.
Allied Venture Partners' guide to assessing founders during due diligence suggests watching how founders handle disagreements in interviews, and flags reference feedback that contradicts the founder's story. For the wider picture of what gets scored, read how investors evaluate a founding team.
What do VCs ask about roles and decisions?
They want to know who has the final call in each area and how you break a tie. Expect questions like these:
- Who has the final say on product, hiring and fundraising?
- What happens when you disagree and neither of you will move?
- Do your titles match what each of you actually does?
- How do you write decisions down so you both remember them the same way?
A vague answer worries investors more than an answer they dislike. If you cannot say who owns a call, you are telling them the question has never been tested, or that it was tested and left open.
What do VCs ask about equity and vesting?
How you reached the split, whether everyone vests, and what happens to shares if someone leaves. CRV calls the split "one of the few artifacts that shows how you make irreversible decisions together", and notes that a bare 50/50 with no vesting and no tie-break reads as conflict avoidance.
Expect to be asked:
- How did you arrive at the split, and has it changed?
- Is every founder on a vesting schedule with a cliff?
- What happens to a founder's equity if they leave in year one, or year three?
- Is your agreement written down?
The bigger flag is a cap table where a co-founder who left early still holds their full stake. CRV's guide to startup equity structure says institutional investors often treat that as a dealbreaker.
What do VCs ask about conflict between cofounders?
They ask for a real example and listen for how it ended. Typical prompts:
- Tell us about a real disagreement with your co-founder. How did it end?
- Has one of you made a call the other opposed? What happened next?
- How do you talk when something is going wrong?
"We've never really disagreed" gets more scrutiny, not less. It suggests the partnership is untested, or one of you is holding things back. If you have struggled to have these talks honestly, work through one before the raise; our cofounder conflict resolution guide is a place to start. The red flags VCs watch for covers what else raises doubt.
What do reference calls reveal?
Whether your story holds up when you are not in the room. Investors ask references who drives final decisions, how the two of you settle disagreements, and whether either founder has gone around the other. Some will also call people you did not list.
What matters most is that the references roughly match what you said. A mismatch between your account and theirs is harder to recover from than one weak metric.
How should cofounders prepare for diligence?
Prepare the relationship the way you prepare the financials: together and in advance.
- Write down your real decision rights. Not the org chart, the real one. Settle any disagreement about it now.
- Check your vesting. CRV's diligence checklist says founder vesting commonly runs four years with a one-year cliff. If yours was never set up, fix it before you raise.
- Pick one real disagreement. One you resolved and can both describe the same way.
- Compare your answers privately. The Cofounder Alignment Check shows where your answers match and differ, while you still have time to close the gaps.
- Tell your references. Let likely references know a call may come, so they are not caught off guard.
Frequently asked questions
- Do VCs interview cofounders separately?
- Often, yes. Many investors ask each co-founder similar questions apart, then compare the answers. The gap between the two accounts tells them more than either answer alone. If you have not agreed who decides what, or how equity works if someone leaves, separate interviews are where that shows.
- Is a 50/50 equity split a red flag for investors?
- Not on its own. An equal split with vesting and a written tie-break is fine for most investors. A bare 50/50 with no vesting and no way to settle a deadlock can read as two founders who avoided a hard conversation. Expect to be asked how you reached the split.
- What is the biggest cofounder equity red flag in diligence?
- A former co-founder who left early but still holds a large stake, usually because there was no vesting. It means equity sits with someone no longer building the company. Institutional investors often treat it as a dealbreaker until it is fixed, so sort it out before you start raising.
- How should cofounders answer questions about disagreements?
- Name one real disagreement, say what each of you wanted, and explain how it ended. Pick one you both remember the same way. Saying you never disagree sounds like a partnership that has not been tested yet, or one where somebody is not speaking up.
