US pre-IPO companies

Own shares in a top US startup?

Guides for people who hold equity in the biggest US private companies — what your shares or options may be worth, the US rules on exercising and selling, and how a private secondary actually works.

New — the Liquidity Heat Index scores which US private companies actually run programmes that let employees sell before an IPO.

Hold shares in one of these? Value them, understand the US tax, and prepare to turn them into cash — start with your company below.

See the sourced data behind this list in the Private Tech Equity & Liquidity Report 2026.

Independent & educational. We are not affiliated with any company listed. These are plain-English guides for people who already hold shares, options or RSUs — not investment advice, and not an offer to buy or sell any security. Whether to buy or sell, and on what terms, is each person's own decision.

✓ Freshness audited monthly  Last reviewed November 2026. Companies shown are privately held at the time of review; if one lists publicly or is acquired, it leaves this page.
