When founders raise a pre-seed or seed round, investors often ask about the option pool right after valuation. The percentage can look like a routine cap-table input, but its size, timing, and treatment can materially change founder dilution.
This becomes more complicated when the company has outstanding SAFEs. Founders often search for “SAFE notes,” but a SAFE is not technically a promissory note or convertible note. It is a separate financing instrument that generally converts into preferred stock in a later priced round.
At Zecca Ross Law Firm, we help founders model the economics and complete the legal work before they sign financing documents or promise equity to employees. Here is how I recommend approaching the option pool in practice.
An option pool is a reserve of company shares available for equity awards to employees, officers, directors, advisors, and other eligible service providers. The reserved shares remain unissued until the company approves individual grants under a formal equity incentive plan.
Think of the pool as an equity budget. Its purpose is to support a specific hiring and retention plan—not to reach an arbitrary percentage because a term sheet or template says that percentage is “standard.”
The pool should also be distinguished from options already granted. A cap table may show:
All four categories may matter when modeling the company on a fully diluted basis.
Early-stage pools commonly fall in the 10% to 15% range, but peer data should be a reasonableness check rather than the primary sizing method. Carta recommends building the pool from the company’s hiring plan, and CRV similarly ties pool size to stage, hiring needs, and market conditions.
These are planning ranges, not legal requirements. A startup that already has most of its leadership team may need less. A company preparing to recruit several senior executives may need more.
Before agreeing to a percentage, list each anticipated role, the expected grant range, the likely hiring date, and any refresh grants. Then compare that total with the unused shares already available. This bottoms-up analysis gives founders a defensible answer when an investor requests a larger pool.
Option-pool planning should also be coordinated with founder equity splits, vesting, and the rest of the fully diluted capitalization. Looking at any one category in isolation can hide the actual ownership result.
The short answer is that SAFEs do not use shares from the option pool, but SAFE conversion and pool expansion can dilute many of the same holders.
A SAFE generally converts into preferred shares when the company completes a qualifying priced financing. The cap table must therefore model the founder shares, existing option grants, promised awards, unused pool, every SAFE or other convertible security, any proposed pool increase, and the new seed investment together.
Under Y Combinator’s post-money SAFE mechanics, the pre-financing capitalization includes the existing option pool, including issued, promised, and unissued awards. It does not include a new or increased pool adopted in connection with the priced financing. According to YC’s SAFE conversion calculator, that financing-related increase dilutes founders and SAFE holders but not the new-money investors.
That distinction matters. An investor may describe the request as a “15% pool,” but the result changes depending on whether 15% means:
Those are not interchangeable terms. The financing documents and pro forma cap table should define the numerator, denominator, and timing clearly.
The following comparison uses the published example from Carta’s analysis of pre-money and post-money SAFEs. Assume:
In the pre-money example, each SAFE converts into 500,000 shares at $1.00 per share. Because pre-money SAFE investors can dilute one another, their percentages are not fixed in the same way as post-money SAFE ownership.
In the post-money example, each $500,000 SAFE represents 5% before the priced financing based on the $10 million post-money cap. The priced round then dilutes those SAFE holders.
This example is deliberately simplified. It does not mean post-money SAFEs always produce less founder dilution, a larger pool, or the same result across transactions. The outcome depends on the SAFE amounts and terms, valuation caps, discounts, priced-round valuation, new investment, existing pool, promised grants, and the timing and size of any pool increase.
The practical lesson is to model the complete transaction. Do not estimate dilution by dividing a SAFE investment by a valuation cap and stopping there.
The option pool shuffle occurs when an investor requires the company to create or expand the pool before the financing closes and includes that pool in the pre-money capitalization.
For example, an investor may offer a $10 million pre-money valuation while requiring the pool to grow from 5% to 15% before closing. The additional pool shares dilute the existing holders—usually the founders and, depending on the financing structure, SAFE holders—before the investor buys shares. The investor therefore receives the negotiated ownership percentage without sharing in that initial pool dilution.
A post-money pool increase works differently because the new investor participates in the dilution. That treatment is generally more favorable to existing holders, although every deal still needs to be modeled using its actual terms.
This is why valuation cannot be negotiated separately from the pool. A strong headline valuation can be offset by a large pre-closing pool increase.
I recommend that founders respond to a pool request with a cap-table model and a hiring plan, not a generic argument that the percentage feels too high.
Specific responses include:
A reasonable pool is large enough to execute the hiring plan but not so large that founders absorb unnecessary dilution for hypothetical hires years in the future.
The following sequence describes common planning for a Delaware C corporation. It is general information, not state-specific legal advice, and the required approvals and filings depend on the company’s charter, bylaws, existing agreements, financing documents, and the states connected to each grant.
Start with an accurate cap table showing founder stock, all outstanding equity awards, promised grants, the unused pool, SAFEs and other convertible securities, warrants, and the proposed financing.
Run alternative models for the requested pool size and for pre-money versus post-money treatment. This is the time to identify whether the term sheet’s percentage refers to the total pool or only the unallocated portion remaining after closing.
Confirm that the certificate of incorporation authorizes enough shares to cover the proposed pool and the financing. If it does not, the company may need board approval, the required stockholder approval, and a charter amendment before reserving or issuing the additional shares.
Do not confuse authorized shares with issued shares. Pool shares are generally reserved for future grants but remain unissued until the company approves particular awards and the applicable exercise or settlement requirements are satisfied.
The company needs a written equity incentive plan and related forms that fit its capitalization and intended grants. The documents commonly address eligibility, the types of awards available, vesting, exercise procedures, termination treatment, transfer restrictions, and plan administration.
The company should also determine whether each option is intended to be an incentive stock option, or ISO, or a nonqualified stock option, or NSO. Classification affects the terms and tax treatment, and an option should not simply be labeled an ISO without checking the applicable requirements.
The board should approve the plan or amendment, reserve the specified number of shares, approve the related document forms, and authorize the appropriate officers to administer the plan within the resolutions’ limits.
The initial plan and pool expansions generally also require stockholder approval. If additional authorized shares or another charter change is needed, the company must complete the separate approvals and filing required for that amendment. Carta summarizes the board and stockholder approval process.
Creating the pool does not itself grant options to employees. Each grant must be separately approved with the recipient, share amount, exercise price, vesting terms, and other material terms identified.
Option grants involve securities. Private companies commonly rely on Rule 701 for compensatory grants to eligible service providers, but the company must satisfy the exemption’s conditions and consider applicable disclosure requirements.
Counsel should also review relevant state securities requirements based on where the company and recipients are located. The financing itself may involve separate federal and state filings and exemptions.
The exercise price generally must be at least the fair market value of the common stock on the grant date. A startup should obtain an independent 409A valuation before issuing options rather than relying on an informal estimate or the preferred-stock price from the financing.
The grant date is tied to final corporate approval with the material terms established—not an earlier verbal promise or offer-letter reference. A 409A valuation generally remains usable for no more than 12 months, and a material event such as a financing can require an earlier update. For that reason, companies often obtain or refresh the valuation after the seed closing and before approving post-closing grants.
After the plan is effective and the company has a current valuation, the board or an authorized committee should approve each grant. The company should then deliver the option agreement and required notices, obtain the recipient’s acceptance, and explain the vesting and exercise mechanics clearly.
Record each grant, cancellation, exercise, and expiration promptly. Keep the plan, approvals, valuation, grant documents, and recipient acceptances with the company’s corporate records.
A financing is a poor time to discover that offer letters promised equity that was never approved or that the cap table does not match the board records.
Your pool should cover the equity grants reasonably expected before the next financing; 10% to 15% is a common early-stage range, but the hiring plan should determine the final number.
No. A SAFE is not technically a note, and it converts into its own shares rather than consuming pool shares, but the SAFE and pool must be modeled together because both affect dilution.
It can. Under YC’s post-money SAFE mechanics, a new or increased pool adopted for the priced round dilutes founders and SAFE holders but not the new-money investor.
A startup should obtain a 409A valuation before granting options and refresh it after 12 months or sooner if a material event, such as a financing, makes the prior valuation stale.
The board approves the equity plan and share reserve, and stockholder approval is generally also required for the initial plan and later pool expansions.
No. The pool is a reserve of authorized shares; shares remain unissued until the company properly approves grants and the relevant award is exercised or settled.
That is a negotiated economic term. A pre-money increase primarily dilutes existing holders, while a post-money increase spreads dilution across existing holders and the new investor.
An option pool is not just an administrative line on the cap table. It affects financing economics, founder control, employee compensation, tax compliance, and the company’s ability to close a clean seed round.
Before signing a term sheet, founders should understand three things in writing: how many pool shares already exist, how many additional shares the investor requires, and who bears the dilution after every SAFE converts and the financing closes.
