Building an ESOP pool: how much equity should you set aside?

For many founders, launching an employee stock option plan (ESOP) feels like a milestone. It signals that the company is growing, hiring and thinking long term. But before any options can be granted, there is an important decision to make: how much equity should be reserved for employees?

This is where the ESOP pool comes in.

Founders often ask the same questions when setting up an ESOP for the first time. How big should the pool be? What happens if it turns out to be too small? And do you only get one chance to get it right? The good news is that an ESOP pool is not a one-time decision set in stone. While it is important to think carefully about the size of the pool from the outset, it can usually be expanded as the company grows and its needs change.

In this blog, we'll explain what an ESOP pool is, how founders typically determine the right size and when it makes sense to increase it. Keep reading!

What is an ESOP pool and why every growing company needs it

An ESOP pool is a dedicated allocation of shares that can be used to reward employees through stock options. Rather than granting equity directly from founder holdings every time a new employee joins, companies reserve a specific percentage of shares that can be distributed over time.

The purpose is simple: to give employees a stake in the company's future success.

For startups in particular, equity can be a powerful recruitment and retention tool. While larger companies may be able to compete primarily on salary, growing businesses often need additional ways to attract talented people.

Consider a startup that is hiring its first Head of Engineering. The company may not be able to match the salary offered by a large multinational employer. However, offering meaningful equity gives the candidate an opportunity to share in the value they help create. If the company succeeds, the reward can be significant.

This is why many of today's most successful startups have used employee ownership as part of their growth strategy from an early stage.

Creating an ESOP pool: where founders should start

Before deciding how much equity to reserve, founders should think about where the business is heading over the next few years.

One of the biggest mistakes companies make is creating an ESOP pool based solely on their current team size. A better approach is to consider future hiring plans.

The answers to these questions will help determine how much equity you are likely to need.

For example, a startup with five employees that plans to hire a CTO, Head of Sales, Product Manager and several engineers will require a larger pool than a business expecting only one or two additional hires.

Once founders have estimated future hiring needs, they can establish the ESOP scheme, obtain the necessary approvals and begin issuing option grants.

The most effective ESOP pools are built around a hiring strategy rather than a percentage chosen at random.

How much equity should you reserve for employees?

There is no universal answer to this question because every company is different. However, many startups reserve between 10% and 15% of company equity for employee ownership. This range has become common because it generally provides enough flexibility to reward key hires while avoiding excessive dilution.

That said, the right number depends on several factors.

Your growth plans

A business planning rapid expansion will usually require a larger ESOP pool than a company growing more gradually.

If you expect to hire across multiple departments in a short period of time, you'll likely need more equity available for future grants.

The type of talent you need

Senior hires often receive larger option grants than junior employees.

A startup recruiting experienced executives may need a larger pool than a company focused primarily on entry-level recruitment.

Your funding stage

Earlier-stage companies often allocate larger ESOP pools because equity plays a more significant role in attracting talent.

As companies mature and generate more revenue, they may rely less heavily on equity-based incentives.

Your retention strategy

Many companies use ESOPs not only to attract employees but also to retain them over the long term.

This means reserving enough equity for future grants, promotions and refresh awards.
