Methodology snapshot

Growth model: Each year, companies draw growth from a mixture distribution. Most (~88%) draw from Normal(mean, spread), clamped to a negative floor. A high-growth band (~12%) draws from Normal(high-growth mean, spread/2). This reflects realistic variance with occasional breakout companies.

Survival & zombies: At each funding round (every ~2.5 years), companies face survival probability (~50%). Survivors also face zombie probability (~15%) which halts future growth. This models the ~50% per-round attrition observed in Carta data, plus stalled companies that don't die but stop growing.

Dilution: Each funding round dilutes ownership. Seed rounds sell ~20% equity, later rounds ~27%, plus option pool expansion (~1.5% per round). Founder ownership typically falls from 100% to ~20-25% by Series B/C.

VC selection: VCs select from the top 20-30% of companies (by decile) with mild signal strength, reflecting realistic selection bias that's softer than pure top-decile picking. Exit multiples are capped at ~2.5× to match observed fund returns (median TVPI ~1.7×, p75 ~2.5×).
