vs Last Round — unlabeled: the secondary share price against the round's price per share (the tape's own comparison). print: the latest observed print's implied valuation against the last priced round's post-money. mark: the valuation shown against that post-money — no independent print yet. = last round means the two legs are within 0.5%; for a mark basis that means the valuation shown was set by the round itself. A cell that says no priced round on record has a secondary price but no round to test it against — it is never rendered as 0.

Methodology. Rankings are by each company's latest disclosed valuation (roster + weekly enrichment); the "mark" chip shows when that valuation was set. Secondary share prices are point estimates from secondary-market activity — one implied price per name, no bid/ask — refreshed daily (marks overlay as of 2026-09-11), each carrying its own date. "vs Last Round" compares the secondary price to the company's own last primary round per-share price; rows without a usable comparison say so rather than showing zero. Companies marked acquired, defunct, or public are excluded. Educational data, not investment advice.
