Removing someone from your founding team ranks among the most painful decisions you will make as an early-stage founder. The stakes feel enormous because they are. You share equity, history, and in many cases a genuine friendship. But waiting too long to act on a serious problem compounds every other problem your company already has.
This article gives you a concrete framework for making the call, not just the emotional permission to do it.
Why the Pre-Series A Window Is Critical
Before you raise a Series A, your company is small enough that one person can determine whether you survive the next six months. A team of three to five people means each person carries roughly 20 to 33 percent of the total output. If one of them is underperforming, misaligned, or actively damaging culture, you feel it immediately in the numbers and in the room.
Investors running Series A diligence will scrutinize your founding team closely. A cap table dispute, an unresolved co-founder conflict, or a poorly structured departure mid-raise can kill a term sheet. Resolving team issues before you fundraise is not just good management. It is fundraising strategy.
The Three Categories of Firing Offenses
It helps to separate the reasons you might remove someone into three distinct buckets, because the process for each is different.
Performance failure means the person is not producing what the role requires, and coaching has not moved the needle. If your CTO has missed three consecutive technical milestones and you have had direct conversations about each one, that is a performance failure.
Values or trust breakdown means something has happened that makes continued collaboration genuinely untenable. This includes dishonesty with investors, harassment of employees, or misuse of company funds. These situations rarely improve and usually require immediate action.
Strategic misalignment is the subtler and often more common one. You want to build a focused SaaS product; your co-founder wants to pivot to enterprise services. Neither of you is wrong, but you are pulling in different directions every week. Left unresolved, this drains the company of momentum faster than almost any external threat.
Have You Actually Had the Direct Conversation?
Before you make any decision, ask yourself honestly whether you have told this person, plainly and specifically, what is not working. Most founders skip or soften this step because it is uncomfortable. Saying "I think we need to revisit how you're managing the engineering timeline" is not the same as saying "You have missed the last three sprint goals, and I need you to tell me what is blocking you and what will change."
Give the person a real chance to respond to a real description of the problem. Document this conversation in writing afterward, even informally by email. If things do not improve within a defined window (four to six weeks is usually enough at this stage), you have your answer and a record that supports it.
The Equity and Legal Reality
Before you act, review your founders agreement and vesting schedule. Most early-stage teams use a four-year vest with a one-year cliff. If your co-founder is past the cliff, they have already earned a portion of their equity and will keep it upon departure, which is generally fair. If you have no vesting schedule at all, stop reading this article and fix that today.
You should also have a lawyer, even a startup-specialist one on a flat-fee basis, review the departure terms before you have the termination conversation. Negotiating a buyback of unvested shares, a separation agreement, and any IP assignment all need to happen in the right order. Getting this wrong can create a liability that resurfaces during Series A diligence and genuinely scares institutional investors.
Reading the Signal Versus the Noise
Early-stage companies go through brutal stretches where everyone looks like they are failing. Before you conclude that a co-founder is the problem, separate the external pressure from the individual pattern.
Ask yourself: is this person struggling because the circumstances are hard, or are they struggling in ways that are specific to their judgment, effort, or character? A founder who is working hard, communicating openly, and failing at a genuinely difficult problem is a different situation from one who is disengaged, avoidant, or hiding information.
One useful test is to ask whether you would hire this person into this role if they applied today, knowing everything you know. If the answer is clearly no, that is meaningful data.
How to Handle the Conversation Itself
Be direct, be brief, and be kind. Do not build up to the conclusion over a 45-minute conversation. State the decision in the first two minutes, then explain your reasoning, then give the other person space to respond.
Come in with a proposed separation structure already drafted: unvested equity treatment, a transition timeline, any severance you are offering, and how you plan to communicate the departure to employees and investors. Having a proposal ready signals that you have thought seriously about this and that you are not improvising. It also moves the conversation toward resolution rather than argument.
Never announce this to the team or your investors before the conversation happens. Leaks destroy trust in both directions.
The Takeaway
The question is not whether removing a founding team member will be hard. It will be. The question is whether the cost of acting now is higher than the cost of waiting. In almost every case founders describe in retrospect, they waited six to twelve months longer than they should have. Set a clear improvement benchmark, give the person a genuine shot at meeting it, and make the call before your next fundraise forces the issue for you.
