Share price connects valuation to ownership

A priced round adds newly issued shares. Pre-money value describes the negotiated value before the new investment, on a specified capitalization basis. Post-money value adds the new investment under the simple cash-in model.

Divide pre-money value by the agreed pre-round share count to obtain the price per share. Divide investment by that price to obtain new shares. Recompute all percentages using the post-round denominator. Existing holders can retain the same number of shares while their percentage declines.

30 / TheoryOwnership, share prices & option pools

An option pool changes the denominator

A pool reserves equity for future grants on the basis specified in the transaction. The phrase “10% pool” is incomplete without knowing whether it means a percentage before or after the round and whether existing grants or reserves count toward it.

In the source cap-table example, the next investor contributes $10 million at $30 million post-money with a 10% post-money unallocated pool. The investor owns 33.333% and the pool owns 10%, leaving 56.667% for the existing 11 million shares.

Pre-money and post-money value

PRE-MONEY + NEW INVESTMENT = POST-MONEY
Simplified priced round
Assumes the stated ownership basis and treatment of other instruments are clear.
Investor ownership
New investment ÷ post-money value under that simple setup.

$8 million pre-money + $2 million investment = $10 million post-money; new investor owns 20%.

Fully diluted ownership needs a definition

  • Include the instruments and reserved interests specified in the comparison.
  • Options, warrants and convertibles can change the denominator.
  • State whether a pool is created or increased before or after the investment.
  • A percentage is not meaningful without the agreed basis.

Pool timing determines who bears the dilution

A pool established as part of the pre-money capitalization generally changes the ownership and pricing of the existing holders before the new investor receives the negotiated percentage. A pool added afterward can also dilute the new investor. The precise result follows the actual definitions.

Compare offers using the same fully diluted basis and the same target pool. A higher headline valuation can be offset by a larger required pool. Convert the terms into share counts so that the comparison does not depend on ambiguous percentages.

30 / TheoryOwnership, share prices & option pools

Ownership arithmetic and the economic rights

A cap table answers who holds shares or other interests on a defined basis. It does not by itself describe all payout or voting consequences. Different classes can have different rights even when their percentage ownership appears similar.

Check that shares sum to the stated total and percentages sum to 100%. Reconcile investment, price and shares issued. Then link each class to the relevant terms. This keeps the mechanical ownership calculation separate from the later lesson on liquidation preferences.

Reconcile a cap table

  • Shares add to the total on the stated basis.
  • Ownership percentages add to 100%.
  • Investment, price and new shares are consistent.
  • Value and ownership are not confused with cash received by each holder.

Relay's seed round: the reconciled cap table

Illustrative. $4M at $16M pre-money; unallocated pool topped up to 10% of post-money fully diluted shares inside the pre-money; post-money SAFE converts at the $12M cap.

Pool equation: (10,000,000 + 1,571,429 + 400,000) = 11,971,429 = 70% of T, so T = 17,102,041.

Seed price = $4,000,000 / 3,420,408 = $1.1695. Check: 17,102,041 x $1.1695 = $20.0M post-money.

Same $4M, three pool definitions

Where the pool sits, and how large it is, decides who pays for it. Existing shares = 11,971,429 in every case. Illustrative.

Row 2 shows why investors insist on a pre-money pool: if the pool is topped up after the round, the seed investor shares the dilution and ends below its 20%. Row 3 shows why founders should compare effective pre-money: the higher headline price beats the bible terms by $0.7M even though Maya's percentage is lower.

Current practice: seed rounds and option pools

Seed dilution near 18%

Carta's data for software rounds raised in the six months to July 2026 show median seed dilution of 18% and a median seed of $4.1M at a $24.3M valuation. Relay's illustrative $4M at $20M post (20% sold) is close to the market; a lead asking for 25–30% would be well above the median.

Pools are smaller than investors often ask

Carta reported in June 2025 that the median option pool after a seed round is about 12%, that companies typically use 60–70% of the pool before the next raise, and that requests for 15–20% are usually too large. A hiring plan is the founder's best argument on pool size.

Post-money SAFEs shift the pool cost to founders

Under the standard post-money SAFE, a pool increase made in connection with the priced round is excluded from the capitalization used to convert the SAFE. SAFE holders keep their fixed percentage of the pre-round capitalization, and founders bear the top-up. In Relay's seed, the SAFE converts at $0.9545 into 1,571,429 shares whatever pool the seed lead demands. Exact treatment depends on the documents signed; confirm with counsel.

The source’s pool-adjusted seed round

Founders hold 10m shares, the pre-seed investor holds 1m and no unallocated pool exists. A new investor contributes $10m at $30m post-money. The terms require an unallocated pool equal to 10% of post-money fully diluted shares. Use the source’s simple priced-round definitions and ignore other instruments.

Your task

Solve the fully diluted total, new investor shares, pool shares, price and founder ownership. Reconcile all percentages.

21
30 / DebriefOwnership, share prices & option pools

Worked answer and reasoning

  • New investor ownership is 10/30 = 33.333%. Existing holders retain 56.667% after the 10% pool.
  • Total shares = 11m/56.667% = 19.411765m. Investor shares = 6.470588m and pool = 1.941176m.
  • Price is about $1.54545. Founder ownership is 51.515%, pre-seed 5.152%, investor 33.333% and pool 10%. Counts and percentages are rounded.

Venture step: Build Relay's seed cap table

Relay · venture step 30

Month 16. Relay has 10,000,000 founder shares (Maya 5.2M, Daniel 4.8M), a 1,000,000-share pool with 400,000 options granted (Priya 300,000, two engineers 50,000 each), and $1.5M of post-money SAFEs at a $12M cap that convert into 1,571,429 shares at $0.9545. The seed lead offers $4,000,000 at $16,000,000 pre-money ($20M post) and requires the unallocated pool to be 10% of post-money fully diluted shares, with the top-up counted in the pre-money.

Your task

Produce a reconciled post-seed cap table (shares, percentage, value at the seed price) for every holder, with the pool equation written out, the seed price, the new pool shares, and the effective pre-money valuation for existing holders.

Venture step: worked reasoning

  • Existing holders other than the unallocated pool: 10,000,000 + 1,571,429 + 400,000 = 11,971,429 shares. They must equal 100% - 20% (seed) - 10% (unallocated pool) = 70% of the post-money total, so T = 11,971,429 / 0.70 = 17,102,041 shares.
  • Seed shares = 20% x T = 3,420,408; price = $4,000,000 / 3,420,408 = $1.1695 (above the $0.9545 SAFE cap price, so the cap applies). Unallocated pool = 10% x T = 1,710,204, of which 600,000 exist and 1,110,204 are new.
  • Post-seed ownership: Maya 30.41%, Daniel 28.07%, SAFE holders 9.19%, granted options 2.34%, unallocated pool 10.00%, seed 20.00%. Shares sum to 17,102,041 and percentages to 100%.
  • Effective pre-money: the existing 11,971,429 shares are worth 11,971,429 x $1.1695 = $14.0M. The other $2.0M of the $16M headline pre-money is the unallocated pool (1,710,204 x $1.1695), of which about $1.3M is the new top-up. That reserve dilutes the existing holders, not the seed investor.
  • Negotiating lever: if the hiring plan to Series A needs about 700,000 options (illustratively a VP Sales at 171,000, three managers at 85,500 each and nine engineers at 30,000 each, 697,500 in total, or 4.1% of 17.1M), a 6% pool is enough. That gives T = 11,971,429 / 0.74 = 16,177,607 shares, of which 970,656 are unallocated, about 40% more than the plan needs, and Maya would hold 32.14% instead of 30.41%. Recompute the table before agreeing to any change.

Reasoning traps

Accepting '10% pool' without a basis

Ten percent of the pre-round shares, of the post-money total, granted plus unallocated, or unallocated only: each gives a different share count and price. Write the equation (others / (1 - investor% - pool%)) into the term sheet discussion and check it against share counts.

Comparing offers on headline pre-money

A larger pool counted in the pre-money transfers value from existing holders to future hires. Convert every offer to effective pre-money (existing shares x price): Relay's $16M headline is $14.0M to the people already on the cap table.

Sizing the pool to a round number

An oversized pool permanently dilutes founders by the unused amount, and unused options do not return value to them. Size the pool from a hiring plan to the next round using a grant chart, and argue down a 15–20% request with that plan.

What you can now explain

Relay's reconciled post-seed cap table: 17,102,041 fully diluted shares at $1.1695, with Maya 30.41%, Daniel 28.07%, SAFE holders 9.19%, granted options 2.34%, unallocated pool 10.00% and seed 20.00%, plus the $14.0M effective pre-money and a hiring-plan argument on pool size.

  • A pool top-up counted in the pre-money is paid for entirely by existing holders, so price per share = investment / (investor% x post-money fully diluted shares).
  • Solve the cap table with one denominator equation: shares held by everyone except the new investor and pool = (1 - investor% - pool%) x total.
  • Compare term sheets on effective pre-money and share counts, not headline valuations or percentages.
