How to Remove a Cofounder (and When It's the Right Call)
If you are reading this, you have probably been thinking about it for months and saying it to no one. That delay is normal and it has a cost: every month of avoidance adds evidence your team can see and you cannot discuss, and it makes the eventual conversation harder rather than easier. This page is deliberately practical. First, how to test whether removal is actually the right call — because a meaningful share of founders who reach this page are looking at a solvable role problem. Then, if it is, how to do it in a way that protects the company, the equity, and as much of the relationship as can survive.

Test the conclusion before you act on it
Removing a cofounder is close to irreversible and expensive in every direction, so the conclusion deserves a real test rather than the accumulated weight of frustration.
Three questions do most of the work.
Has the actual conversation happened?Not hints, not a difficult quarterly review, not a conversation about “how things are going.” A direct conversation naming the specific gap, what needs to change, and by when. A surprising number of founders reach the removal decision without their cofounder ever having been told plainly that there is a problem of this magnitude. If that is your situation, you do not yet have the information to decide — people frequently change when the stakes are finally stated.
Is the problem the person or the seat?A cofounder failing as VP Engineering may be an excellent principal engineer, and a cofounder failing as COO may be a strong first product hire. The company needs the seat filled correctly; it does not necessarily need the person gone. Founders collapse these two questions and end up removing capability the company still wants.
Would you hire them into this role today?If yes, the problem is fixable. If no but you would hire them into a different role, you have a role problem. If no to any role, you have a removal.
Run these honestly. If you cannot answer the first one yes, the next step is a conversation, not an exit.
Four situations, and which ones warrant removal
Four situations bring founders to this page. They look similar in the moment and resolve very differently.
Capability mismatch at the current stage.Your cofounder was right for the first two years and has not grown into the role the company now needs. No villain, and the most common version. Frequently resolvable by moving them to a role that fits, with the title and reporting line honestly adjusted. Warrants removal only when there is no such role, or when they will not accept one.
Disengagement.Effort or presence has dropped materially and has not recovered after being named. Ask about cause first — burnout, health, a life event, or genuine loss of interest all present identically and have completely different remedies. Burnout is fixable. Genuine loss of interest is not, and the kindest thing is to make the exit easy rather than manage a disengaged founder for another two years.
Behaviour that is damaging the company.Undermining decisions in front of the team, misleading the board, treating people badly. This one moves faster than the others, because the cost compounds and every week you tolerate it sets the standard for everyone watching. Document, act, and do not run a long improvement process on conduct.
Irreconcilable direction.Both of you are capable and honest and want different companies. Not a performance issue at all — a structural incompatibility. Often the cleanest exit to negotiate, because there is no need for anyone to be wrong, and the framing genuinely matters to how it lands.
Name which one you are in, because it determines the conversation, the terms you offer, and what you say to the company.
The six things to settle before the conversation
Do not open this conversation with anything on this list unresolved. You get one attempt at the first five minutes.
Your actual decision.Whether this is a final decision or an opening position. If you are undecided, do not have the conversation — an ambiguous version does more damage than either clear alternative, because it starts a negotiation you have not prepared for.
Legal and equity position.Understand the cap table, vesting schedule, acceleration provisions, board composition, any founder agreement, and your own authority to do this at all. Get a lawyer before the conversation, not after. Nothing in this article is legal advice, and the specifics vary by jurisdiction and by document.
Board and investor alignment.If you have a board, key investors should not learn about this from your cofounder. Align first, in a controlled way.
The offer.What you propose: severance, vesting treatment, title on the way out, timeline, ongoing role if any, what you will say publicly. Coming without an offer turns the conversation into an ambush and the response into pure defence.
The company message.What you will say internally, when, and to whom first. Decide before, because you will lose control of the timeline once the conversation happens.
Your own account of it.Get honest with yourself about your contribution to the situation — the feedback you never gave, the role you never defined, the growth you never funded. Not to talk yourself out of the decision. Because your cofounder will raise it, they will be partly right, and a founder who has already accepted their share handles that moment far better than one who is surprised by it.
How to have the conversation
In person, privately, and never on a Friday afternoon or before a holiday — people need access to advisers and to you in the days that follow.
Lead with the conclusion. Not a build-up, not a review of history. “I’ve come to the conclusion that you shouldn’t be in this role, and I want to talk about how we handle it well.” Making them guess for ten minutes is a cruelty disguised as gentleness.
Give the real reason, once, specifically. Vague reasons produce years of speculation and resentment. One clear, honest, non-character-based sentence is what allows someone to eventually accept it. Then stop — do not stack five reasons, which reads as a case being built rather than a decision being explained.
Do not negotiate the decision, and do negotiate the terms. That distinction needs to be explicit, or the whole conversation becomes an attempt to relitigate the conclusion.
Expect that it will not resolve in one meeting, and say so. Offer the terms in writing, name a second conversation in a few days, and let them get advice. Deals pushed to signature in one sitting are the ones that come back as disputes.
Acknowledge what they built. Genuinely, not as a softener. They started this with you, and whether they accept the decision in two weeks or two years depends substantially on whether the exit denied their contribution.
The mechanics: equity, vesting, and the exit
This is where cofounder exits become expensive, and where you need real counsel rather than an article. A few principles worth holding.
Unvested equity is a contract question, not a moral one. What accelerates, what is forfeited, and what can be repurchased is determined by documents you signed, possibly years ago. Read them before you form a view about what is fair.
Vested equity is generally theirs. Attempting to claw back vested founder equity is the single most reliable way to turn a difficult exit into litigation, and litigation with a cofounder is disproportionately destructive because they know everything about the company.
Be more generous than the minimum, and know why. Not out of guilt — because a departing cofounder remains a shareholder, a reference, and a source of the story others hear. The difference between a clean exit and a bitter one is usually a few months of severance and a small amount of vesting treatment, which is cheap against the alternative.
Get the paperwork done properly. Separation agreement, board consents, resignation from any board or officer role, IP assignment confirmations, and clarity on what each of you will say. Loose ends here reliably resurface during diligence.
And decide the title and narrative deliberately. “Stepping back from day-to-day to focus on X” is often accurate and serves both parties. A story that is misleading will not hold, and being caught in one costs you more internally than the truth would have.
Telling the company
Your team will know something happened before you announce it, and the vacuum fills with a worse story than the real one.
Tell the people closest to your cofounder individually and first — their direct reports especially, who are calculating their own security. Then the company, promptly and in person or live, not by written note alone.
Say something true, brief, and respectful, and be clear about what happens next: who owns what now, what does not change. That second part is most of what people need. Do not litigate the reasons publicly, and do not pretend it was mutual if it was not — people can tell, and a transparent falsehood costs you more credibility than a plain “this was my decision, and I’m not going to go into the details out of respect for them.”
Then expect two to three months of unsettled atmosphere and some departures among people loyal to them. That is a normal cost, not a sign you handled it badly.
What founders get wrong
A short list, in order of frequency.
Waiting far too long, until the situation is visible to everyone and the delay itself has become a second problem. Never having had the direct conversation, then treating the absence of change as proof. Removing a person when the problem was a role. Making it about character when it was about fit — which guarantees the relationship does not survive. Being cheap on terms and buying years of resentment for a small saving. Leaving the internal narrative to chance. And doing all of it alone, without a single honest conversation with someone who has no stake in the outcome.
Where Blomma fits
This is one of the loneliest decisions in company-building. You cannot discuss it with your team, your investors have a position, and your mutual friends are compromised the moment you raise it.
Blomma is an always-on AI career coach with no stake in what you decide. Use it to test the conclusion before you commit — including the uncomfortable question of whether you ever actually gave the feedback. Use it to work out which of the four situations you are in, and whether a role change would serve the company better than a removal. Then use it to prepare the conversation itself: the opening sentence, the single honest reason, the line between the decision and the terms, and the response when they raise your part in it. For a situation this consequential, you can also bring in a human coach who has done it..
Removing a cofounder is sometimes the right call and it is never a small one. Done early, honestly, and with decent terms, companies recover from it and so do relationships. Done late, vaguely, and cheaply, it becomes the thing that defines the next two years.
