ESOP pool: meaning, how startups size it in India and examples

An Employee Stock Option Plan, or ESOP, gives staff the right to buy shares at a fixed price in the future. The ESOP pool is the reserve of shares the company keeps aside for that purpose. Some of the pool has been granted to people, some has been exercised, and the rest is unallocated and waiting for future hires.

The pool is a promise on paper. Until options are granted and vested, the shares in the pool belong to nobody, but they are counted in the company's fully diluted share count.

Under section 62(1)(b) of the Companies Act, 2013 a company may offer shares to employees under a scheme only if shareholders pass a special resolution, which needs at least 75% approval. The Companies (Share Capital and Debentures) Rules, 2014, in Rule 12, set the details, as of November 2026.

The rule says that options go to employees and directors of the company, but not to promoters or to a person holding more than 10% of the company's shares. A special relaxation applies to startups recognised by the Department for Promotion of Industry and Internal Trade (DPIIT), which can grant options to promoters for a limited number of years after incorporation. The rules also require a gap of at least one year between the grant of an option and its vesting. Read the current rule text for the exact wording.

• Special resolution of shareholders is needed.
• Eligible: employees and directors, with limits on promoters and 10% holders.
• Minimum one year between grant and vesting.
• Relaxations apply to DPIIT-recognised startups.

There is no legal size. In practice, startups often reserve something in the range of 8% to 15% of fully diluted shares, with early-stage companies sometimes toward the higher end, since they hire many people before the next round. This is a rule of thumb, not a requirement, and it varies by stage and by how many senior hires are planned.

Investors look at the unallocated part of the pool. A common approach is to size it so that it covers planned hiring for the next 12 to 24 months. A pool that is too small forces a top-up soon, while one that is too big dilutes the founders for no reason.

Many term sheets say the pool must be increased to a target percentage before the new money arrives. This is called the option pool shuffle. Because the pool is included in the pre-money share count, enlarging it lowers the price per share the investor pays on a fixed headline valuation, and the dilution falls on the existing shareholders.

The new investor is not diluted by the extra pool, because the investor's stake is calculated after it exists. The guide on pre-money versus post-money valuation shows how the order of steps changes the numbers.

Founders and earlier investors, mainly. When the pool expands before a round, everyone who already owns shares sees their percentage drop in proportion. After the round, the new investor and the pool's holders also share in the later dilution.

When options are granted from an existing pool, ownership does not change on the day, since the shares were already counted. Dilution is felt when the pool is enlarged, not when options are granted from it.

The cap table lists the pool as its own line. It usually shows options granted, options exercised and options still available. Some cap tables show a fully diluted view, which counts the whole pool, and a basic view, which counts only issued shares. Investors price a round on the fully diluted view. See the guide on cap tables for the layout.

A grant gives an employee the right to buy a set number of shares, but the right is earned over time. This is called vesting. A common pattern in Indian startups is four years with a one-year cliff: nothing vests in the first year, a quarter vests at the end of the first year, and the rest vests in monthly or quarterly parts. The Companies Rules require at least one year between grant and vesting, which fits the one-year cliff.

Once an option has vested, the employee can exercise it by paying the strike price, and receive shares. Options that are not yet vested usually lapse if the person leaves, and the shares return to the pool for someone else. Vested options may also lapse if not exercised within a set period after leaving, which the plan states.

• Grant: the company offers options at a strike price.
• Vesting: the right is earned over a schedule, often four years.
• Exercise: the employee pays and receives shares.
• Lapse: unvested or unexercised options return to the pool.

Some companies create an ESOP trust that holds shares for employees, rather than issuing fresh shares at each exercise. Others run a buyback or a secondary sale that lets employees sell vested shares before an IPO. These events make the pool more real, because employees get cash. They are also reported in news, so a headline about an ESOP buyback usually refers to this step.

Tax applies at several points, including when options are exercised and when shares are sold, so employees should read the plan and take advice. This page does not cover tax in detail.

Employees at a startup that has not listed should ask three plain questions: what is the strike price, how many options vest each year, and what happens to vested options after leaving. The answers are in the grant letter and the plan document, and they decide whether the pool is worth anything to the person holding the options.

A small pool is not always bad for staff. If a company hires slowly and keeps a modest reserve, each grant can still be meaningful. A large pool in a company that never lists, on the other hand, may give options that are hard to turn into cash.

A big pool does not mean employees will get rich. Options are worth something only if the company grows and the shares can be sold, for example in an IPO or a secondary sale. Employees should check the strike price, the vesting schedule and what happens to vested options if they leave. For headlines, an ESOP buyback or ESOP pool top-up is a company event, not a measure of value. This page is not legal or tax advice, so consult a professional.
