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

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: Pooled Investment Fund / 506(b) (83,801 filings); Pooled Investment Fund / 506(c) (8,096 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.
