What dilution actually costs a founder

Raise $2M at an $8M pre-money valuation and the post-money is $10M. The investors own twenty percent, and every existing shareholder's stake is multiplied by 0.8. Two founders splitting the company evenly go from fifty percent each to forty percent each.

Nothing about that is unfair or unusual. The important part is that it happens repeatedly, and the effects multiply rather than add. Four rounds at twenty percent each leave the original holders with 0.8 to the fourth power — about forty-one percent — before any option pool is carved out.

A founder owning one hundred percent of a company worth two million dollars has two million dollars. A founder owning fifteen percent of a company worth four hundred million has sixty million. Dilution is only bad when the capital raised fails to grow the company by more than the share given up.

That reframing is not permission to raise carelessly. It is a test to apply to every round: does this money plausibly grow enterprise value by more than the percentage it costs? Money raised with a specific plan usually passes. Money raised because it was available usually does not.

Every priced round creates or expands an employee option pool, and it is nearly always carved out of the pre-money valuation. That means it dilutes existing shareholders only — the new investor's percentage is calculated after the pool exists.

Across a full financing path the pool typically consumes fifteen to twenty percent of the company, paid almost entirely by the founders. It is money well spent when it buys people who materially change the outcome. It is pure loss when the pool is sized to a round number rather than to an actual hiring plan.

Ownership percentage describes what you get after everyone with a preference has been paid. In a strong exit this hardly matters, because investors convert to common and take their percentage. In a mediocre exit it matters enormously.

A founder owning twenty percent of a company that sells for eighty million, with sixty million of stacked preferences ahead of them, receives twenty percent of twenty million — four million, not sixteen. Reading the ownership column without reading the preference stack produces a number that is simply wrong.

Raising too much too early is first by a wide margin. Early money is the most expensive money the company will ever take, because it is priced against the lowest valuation the company will ever have. A million dollars raised in the garage can cost ten percent of the company; the same million at Series B costs well under one percent.

Second is agreeing to a large pre-money pool without a hiring plan. Third is accepting a founder vesting reset without credit for time already served — a clause that can quietly convert years of completed work into unvested shares.

Garage to IPO tracks founder equity across every financing event and displays it in the KPI header. Raising a round updates it instantly, so the trade between cash today and ownership later is visible at the moment the decision is made rather than years afterwards.

The bootstrapped path exists for exactly this reason. Reaching a billion-dollar valuation with sixty percent ownership plays completely differently from reaching the same valuation with twelve percent, and the founder ledger records the difference across careers.
