Dilution

Every funding round creates new shares, which reduces your percentage of the total. Dilution isn't bad — your smaller slice of a bigger pie is usually worth more.

Pre-money vs post-money

Pre-money valuation is the company value before the investment. Post-money = pre-money + investment. Investors own raise ÷ post-money.

Typical founder dilution

After pre-seed + seed + Series A, founders often own 40–60% combined. VCs use the 20% dilution rule per round as a rough target.

Paper value vs real value

Your shares are worth nothing until a liquidity event (IPO, acquisition). Paper value is useful for benchmarking, not spending.
