Pre-IPO investing can be attractive because private companies may grow before public listing, but the risks are materially different from public stocks: limited liquidity, limited disclosure, valuation uncertainty, fees, transfer limits, and possible total loss.

Private shares may not have an active buyer when the investor wants to exit. Resale can require legal review, company consent, transfer-agent processing, or a new exemption from registration.
An investor should be prepared for a long holding period and should not treat private shares as cash-like or public-stock-like.
Public stocks have visible exchange prices. Private-company marks can come from funding rounds, secondary transactions, tender offers, estimates, or platform indications.
Those numbers can diverge from a final executable price after fees, structure, share class, seller negotiation, and transfer approval.
Private placements do not always provide the same disclosure required in registered public offerings. That can leave investors with less information for valuation and risk decisions.
This is why Segmara keeps risk notes next to every company page.
Data-driven private-share buying needs risk math as well as valuation math: price, share class, fees, holding period, and exit probability all matter.

Funding marks, tender marks, and final terms can diverge
IPO timing, tender timing, and exit routes can change
| Stage | Date | Valuation / price signal | Why it matters |
|---|---|---|---|
| Seed / early | Highest uncertainty | Sparse price data | The valuation can move dramatically or go to zero. |
| Series B-D | Growth risk | Revenue and unit economics matter | A higher round price does not remove business-model risk. |
| Late stage | Secondary risk | Share class, fees, and transfer limits | A private mark can differ from the final economic exposure. |
| IPO / exit | Public repricing | Lockups and market multiples | The IPO can validate, compress, or reset private valuations. |
