The correction to the list

The article published in November 2020 reused older company valuations and activity figures without a consistent as-of date. Its list has been withdrawn rather than presented as today's ten most valuable startups. A company's private financing valuation, acquisition price and stock-market value are different measures, and a company that has gone public should not automatically remain in a private-startup ranking.

What a meaningful comparison needs

Record the company identity, date, currency, instrument and rights included in the transaction. In a funding round, headline valuation does not fully describe preferences, future conversion or dilution. YC's SAFE documentation illustrates why the instrument matters. The fictional document-review image and early funding-budget scene explain these activities; they do not show actual terms for a named company or support an investment recommendation.
