How to design equity refresh plans for startup retention

Retaining early employees is one of the most significant challenges a founder faces as a company matures. Most initial equity grants follow a standard four year vesting schedule. As employees approach the end of this period, their financial incentive to remain with the company often decreases. This phenomenon is frequently called the vesting cliff. If a founder does not have a plan to address this, they risk losing the institutional knowledge and talent that built the foundation of the business. An equity refresh plan is a strategic tool designed to provide additional stock options or restricted stock units to existing employees. The goal is to maintain a consistent level of unvested equity to ensure that key contributors remain focused on long term growth. This process requires a balance between rewarding loyalty and managing the overall dilution of the company equity pool. In this guide, we will look at how to identify the right time for refreshes and how to structure them effectively.

Before you begin offering more equity, you must understand the current state of your cap table and the vesting status of your team. When I work with startups I like to start by creating a spreadsheet that tracks the unvested value of every key hire. This is more important than looking at the total percentage they own. An employee who owns one percent of a company but has zero shares left to vest is a flight risk. You need to identify who is within twelve to eighteen months of being fully vested. This window is critical because it gives you enough time to implement a new plan before the employee starts looking for their next opportunity.

Consider these questions when reviewing your team data:

• Which employees have the most significant impact on our current technical or operational goals?
• What is the current market value of their unvested equity compared to their market salary?
• How much of the total option pool is currently unallocated and available for refreshes?
• What is the replacement cost for a specific key hire if they were to leave today?

Focusing on these data points allows you to move away from emotional decisions and toward a logical framework. It is common for founders to hesitate because they fear dilution, but the cost of losing a key lead engineer or a head of sales is almost always higher than the cost of a small percentage of additional dilution. Movement in this area is essential. It is better to have a clear, imperfect plan than to spend months debating the exact percentage while your best people walk out the door.

There are several ways to structure a refresh plan, and the right choice depends on your company stage and culture. The first common method is the boxcar grant. In this model, the new grant is issued now but the vesting only begins after the previous grant has fully vested. This keeps the total equity compensation predictable and extends the retention period by another four years. The second method is the top up grant. This involves granting a smaller amount of equity that starts vesting immediately and overlaps with the existing grant. This is often used to keep the total unvested value at a specific level year over year.

When I work with startups I like to evaluate the evergreen model as well. In an evergreen model, employees receive a small, set amount of equity every year. This eliminates the cliff entirely because there is always a rolling amount of unvested stock. While this requires more administrative work, it creates a culture of continuous ownership. You should ask your finance lead or legal counsel which of these structures fits your current bylaws and tax situation. Do not get bogged down in the complexity. Pick a structure that your employees can easily understand. If they cannot calculate the value of the refresh, it will not serve as an effective retention tool.

Once you have a structure, you need to decide how much to give. Equity refreshes are not typically as large as initial hire grants. A common benchmark for a refresh is twenty five to fifty percent of what a new hire in that same role would receive today. However, this is not a hard rule. You must consider performance and the current valuation of the company. If the company valuation has increased significantly, a smaller number of shares might carry much higher value than the original grant did.

I suggest using a formulaic approach to ensure fairness across the organization. You might categorize employees into tiers based on their impact. For example:

• Tier one consists of executive leadership and foundational engineers who receive a higher percentage.
• Tier two consists of high performing managers and individual contributors.
• Tier three consists of solid performers who are meeting expectations.

This tiered approach helps you manage the total burn rate of your option pool. It also provides a clear answer when employees ask why they received a certain amount. Transparency in the process, even if you do not share specific numbers across the whole company, builds trust. If you are constantly making one off deals with individuals, you will eventually create a cap table that is impossible to manage and creates resentment among the team.

The way you communicate an equity refresh is just as important as the grant itself. If an employee just sees a notification from a stock management platform without context, the impact is lost. When I work with startups I like to have founders sit down with each recipient to explain the why behind the refresh. This is an opportunity to reinforce their value to the company and to discuss the future vision of the business. You are not just giving them shares, you are asking them to recommit to the next phase of the journey.

Ask yourself these questions before the rollout:

• Can I clearly explain how the value of this new grant was determined?
• Does the employee understand the potential upside if the company hits its next major milestone?
• Is the board of directors aligned on the total amount of dilution this plan represents?
• Have we updated our legal documents to reflect the new grants?

Speed is a competitive advantage in talent retention. If you identify a retention risk, move quickly to address it. Many founders spend too much time trying to find the perfect market data. The reality is that market data is often lagging. Your internal data and your relationship with your team are better indicators of what is necessary. A startup environment is defined by its ability to act on information faster than a large corporation. Use that to your advantage here. By the time a large company finishes its compensation review, you could have already secured your key hires for the next four years.

Every equity refresh increases the total number of shares outstanding, which dilutes all existing shareholders, including the founders and investors. This is a natural part of growing a company, but it must be managed with precision. You should always maintain a long term forecast of your option pool. If you are refreshing too many people too generously, you may run out of equity to hire new talent or for future funding rounds. Conversely, if you are too stingy, you will lose the very people who make the equity valuable in the first place.

Think of equity as a finite resource that must be reinvested into the most productive parts of the business. Your early employees are your most tested assets. They have already proven they can operate in the chaos of a startup. Investing in their retention is often more efficient than spending capital on recruiting, onboarding, and training new staff who may or may not work out. In the end, the success of your business depends on the collective effort of a motivated team. An equity refresh plan is not just a financial transaction. it is a commitment to the people who are building the future of the company alongside you.
