How to manage an underperforming cofounder and address equity concerns

Building a startup is an exercise in resource allocation and the most valuable resource available is founder time. When one member of the founding team stops contributing at the expected level, it creates a drag on the entire organization. This article explores the objective reality of underperformance and provides a structure for addressing it. We will cover how to move from subjective feelings to objective data, the mechanics of a formal performance conversation, and the technical aspects of equity clawbacks. The goal is to ensure the company continues to move forward, as stagnation is the primary cause of startup failure. Movement and resolution are always preferable to prolonged internal debate.

When I work with startups, I often find that the primary hurdle to addressing a cofounder issue is the lack of objective metrics. Founders often operate in a cloud of shared assumptions. When those assumptions fail, the result is usually resentment rather than resolution. To fix this, you must move the discussion away from personality and toward output. Start by reviewing the original roles and responsibilities defined at the inception of the company. If these were never documented, now is the time to write them down based on current business needs.

Create a list of key performance indicators or specific milestones that were assigned to the cofounder in question. Ask yourself several questions to clarify the situation. What were the specific deliverables expected over the last quarter? Which of these were met, and which were missed? Is there a documented reason for these failures, such as a shift in company strategy or a lack of external resources? By framing the problem through the lens of business outcomes, you remove the emotional weight of a personal attack. This scientific approach allows you to present a case based on facts, which is essential for any following legal or structural changes.

Once the data is gathered, you must engage in a direct conversation. This is not a casual check in or a social meeting. It is a formal discussion about the future of the company. In my experience, the most effective way to handle this is to be blunt but professional. State the purpose of the meeting clearly. You are there to discuss the divergence between their current output and the requirements of their role. Use the data you collected to illustrate the gap. This prevents the conversation from devolving into a debate about intent or effort.

During this meeting, it is helpful to ask the cofounder for their perspective on the data. You might ask: How do you perceive your current contributions relative to our initial goals? Are there specific blockers that I am unaware of that are preventing you from executing? Do you still feel aligned with the long term vision of this business? Listen to the answers, but do not let them derail the focus on output. The objective is to reach a shared understanding that the current state is unsustainable. Movement is required, whether that means a change in behavior, a change in role, or a complete exit from the organization.

If the cofounder acknowledges the gap and expresses a sincere desire to improve, you can implement a performance improvement period. This is a time bound window, usually thirty to sixty days, with specific, non negotiable milestones. This stage is critical because it tests whether the underperformance is a temporary lapse or a permanent mismatch. When I help teams set these up, I insist on weekly check ins to monitor progress. This creates a high stakes environment that forces a resolution quickly.

During this period, you should ask: Is the individual demonstrating a renewed sense of urgency? Are the technical or operational errors being corrected? Is the rest of the team noticing a positive shift in momentum? It is important to avoid the sunk cost fallacy here. Just because someone was a great partner in the early stages does not mean they are the right partner for the current stage. If the milestones are not hit by the end of the period, you have the empirical evidence needed to move to the next phase, which involves adjusting their relationship with the company.

If the performance does not improve, you must address the cap table. Equity is meant to incentivize future value creation, not just reward past participation. This is why professional startups use vesting schedules, typically over four years with a one year cliff. If a cofounder leaves or is removed before their shares have fully vested, the company usually has the right to buy back the unvested portion at a nominal price or simply cancel them. This is often referred to as a clawback mechanism.

Review your shareholders agreement or bylaws to understand the specific terms you have in place. Common questions to ask your legal counsel include: Does the agreement allow for a buyback in the event of termination for cause or without cause? What is the defined process for executing a clawback? If there is no formal vesting schedule in place, you are in a difficult position that may require a negotiated settlement. In these cases, it is often necessary to offer a separation agreement where the underperforming cofounder agrees to give up a portion of their equity in exchange for a clean break or a small cash payment. Protecting the equity pool for future hires and contributing founders is a primary responsibility of the leadership.

The final stage is the actual transition. Whether the cofounder is moving to a diminished role as a passive advisor or leaving the company entirely, the process must be handled with precision. All access to company systems, intellectual property, and financial accounts must be secured. A formal announcement should be made to the rest of the team that focuses on the future and the stability of the company. Avoid discussing the specifics of the conflict or the performance issues to maintain professional standards.

Reflect on the lessons learned during this process. How can you improve your hiring or cofounder selection process in the future? What changes need to be made to your legal documents to prevent a repeat of this situation? The most important outcome is that the company is no longer stalled by internal friction. By making a hard decision, you have cleared the path for growth. The difficulty of doing this work cannot be overstated, but the cost of inaction is almost always the death of the startup. You are now in a position to reallocate those resources toward someone who will help you build something remarkable.
