## What this supports

Historical post-money company valuations only. Share prices, dilution, security rights, allocation and an IPO exit are not established. These selected milestones are not a claim of the latest valuation.

## Limitations

- Historical research and hypothetical arithmetic, not live quotes, investment advice or an offer to invest.

- Company valuation changes are not shareholder returns. Financing, dilution, security rights and exit access matter.

- IPO offer-price marks are not realized sale proceeds; minimum investments and access are not established.

- User-entered prices and valuations are assumptions, not sourced observations. Fee and carry treatment is stated by each method; taxes and distributions are excluded.

- Selected surviving companies are not representative of private-market outcomes; investments may lose all value.
