Key records

The five facts investors ask about first. Each section states what was searched and when. Items still in human review are not shown.

1. Lawsuits

As reported by the issuer on Form D (Items 12–15), latest filing per offering (one offering = one SEC file number; an amendment updates its offering rather than adding one). "To insiders" = gross proceeds used for payments to executive officers, directors or promoters. "—" = not reported on that filing. Amounts marked (est.) were reported as estimates. "Paid to sell it" = sales compensation recipients named on that filing (Item 12), each linked to FINRA BrokerCheck when a CRD number is reported.

Every row is a Form D or D/A on which the issuer listed this name as a related person. Related-person names are matched on first + last name and the address state on the filing; records that share a name but could not be tied together by a second identifier are listed separately below.

"Similar" = offerings in the same industry claiming the same exemption, filed in the last 5 years: Other Health Care / 506(b) (4,189 filings); Other Technology / 506(b) (17,390 filings); Biotechnology / 506(b) (3,253 filings); Biotechnology / 506(c) (163 filings); ranges are the middle half (25th–75th percentile). Computed by PartnerFacts from SEC EDGAR Form D data as of Oct 23, 2026, 5:45 PM ET. Rows without a range: fewer than 30 comparable filings, or not a Rule 506 offering. No ranking or score.
