Letter grades for every
major pre-IPO company.
A unified rating system for the largest U.S. still-private companies — built from PACER federal court filings, secondary-market transaction data, S-1 prospectus disclosures, regulatory inquiries, and Round Z proprietary diligence. 75 companies. Five subscore dimensions. Quarterly refresh.
Independent & transparent.
The Risk Index is built from public regulatory filings, PACER docket data, S-1 prospectus disclosures, and Round Z's proprietary diligence database. Companies cannot pay to improve their grade — methodology and source data are published in full at /methodology.
Updated quarterly.
Each quarter we re-run the Index against the latest court filings, secondary-market transactions, regulatory inquiries, and disclosure events. Grade changes are timestamped and historical grade trajectories are preserved on each company profile.
Used by institutions.

Don't buy the last round. Buy the governance.
The most expensive mistakes in pre-IPO investing aren't valuation errors — they're governance errors. Founder concentration, undisclosed cross-investments, opaque financial reporting, and customer concentration produce risks that the secondary-market quote doesn't capture. The Pre-IPO Risk Index makes them visible.
