Is an option pool money set aside from the investment?

No. It is a reserve of shares available for equity grants under the equity plan. It affects fully diluted ownership even before options are granted. It does not remove cash from the financing proceeds.

Why do investors ask for the pool in the pre-money?

They often want enough equity available for planned hiring while preserving the ownership percentage their investment buys. Including the increase in the pre-money shifts that dilution to existing holders. Pool size and timing can be negotiated alongside the headline valuation.

Who is diluted if the pool is added after the investment?

Both existing holders and the new investor are diluted when new pool shares are added after the financing shares. In the worked example, a 10 percent post-round pool leaves existing holders with 72 percent and the investor with 18 percent, compared with 70 percent and 20 percent for a pre-money pool.

Is a 10 percent pool target always a 10 percent top-up?

No. A target for the total remaining reserve must account for the unused reserve already available. Outstanding grants and unallocated shares are different categories. The valuation calculator models an additional top-up separately from the existing fully diluted shares you enter, so reconcile the inputs to the term sheet definition.

Do SAFEs change who absorbs a pool increase?

They can. The SAFE capitalization definition and the financing terms determine how conversions and a pool increase interact. Model them together and confirm the treatment with counsel rather than assuming every existing holder shares the pool dilution in the same way.

The option pool shuffle: why the pool sits in the pre-money

By the Vanward team · Last updated October 24, 2026

The option pool shuffle is the dilution that occurs when a financing requires a larger option reserve inside the pre-money capitalization. The extra pool shares enter the denominator used to set the round price, so the price per share falls and the new investor receives more shares for the same investment. Existing holders absorb the pool increase while the investor keeps the agreed ownership percentage. Investors often request this treatment so the company has a hiring reserve when they invest. It is a negotiated term, not an automatic rule.

The pool changes the effective price of the round

A term sheet can promise an attractive pre-money valuation and still leave founders with less ownership than expected. Look at the definition of fully diluted capitalization and any requirement for an unallocated pool at closing. If that reserve is included before the new investment, more shares divide the same pre-money value.

The economic question is who supplies the ownership reserved for future hires. A pool in the pre-money comes from the holders already on the table. A pool added after the investment spreads the dilution across the enlarged table, including the new investor. Actual SAFE conversion terms can change the allocation among existing holders.

A worked comparison at the same valuation

Assume a fictional startup has 8,000,000 founder shares, no existing pool, and no other securities. It raises $2,000,000 at an $8,000,000 pre-money valuation. Compare no pool increase with a new pool equal to 10 percent of the final fully diluted post-round total, added either before or after investment.

Result	No new pool	Pool in pre-money	Pool after investment
Pre-money valuation	$8,000,000	$8,000,000	$8,000,000
New investment	$2,000,000	$2,000,000	$2,000,000
Round price per share	$1.00	$0.875	$1.00
Existing holders after round	80 percent	70 percent	72 percent
New pool after round	0 percent	10 percent	10 percent
New investor after round	20 percent	20 percent	18 percent

With the pool in the pre-money, approximately 1,142,857 pool shares join the pricing denominator. The round price falls to $0.875 and the investor receives approximately 2,285,714 shares. The pool and investor together represent 30 percent after closing, leaving the founders with 70 percent. Share counts here are rounded for explanation.

With the pool added after investment, the investor first receives 2,000,000 shares at $1.00. Adding approximately 1,111,111 pool shares afterward makes the reserve 10 percent of the final total. Founders retain 72 percent and the investor retains 18 percent. The same reserve target produces a different division of dilution.

Repeat the comparison in the valuation and option pool calculator with 8,000,000 existing shares and a 10 percent top-up. Switch whether the pool enters the pre-money. The results isolate pool timing; the tool does not convert SAFEs or notes.

Separate the existing reserve from the requested increase

A request for a 10 percent available pool after closing does not necessarily require 10 percent of entirely new shares. Start with grants outstanding, the unused reserve, promised but unissued grants, and the financing's definition of available pool. An existing reserve can meet part of the target, but it also changes as the financing dilutes it. Solve for the additional shares rather than subtracting percentages with different denominators.

In the calculator, the top-up is additional to your existing fully diluted share input. It is not a reconciliation of the entire equity plan. Avoid counting the same unused reserve once in the existing total and again as newly added shares.

Size the reserve from the hiring plan

List the roles expected before the next financing, their likely equity ranges, and any refresh grants for the current team. Compare the required shares with the reserve still available. That gives the pool discussion a business basis rather than an arbitrary percentage. Negotiate the pool, valuation, and converting instruments together because all three affect founder ownership.

Keep the hiring assumptions, equity plan approvals, grant ledger, and closing cap table together. Counsel should confirm the authorized reserve and conversion treatment. The agreed pool should match both the ownership model and the signed financing documents.
