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.

Counted across every filing this person is listed on (latest filing per offering, per issuer).

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 (5 industry/exemption sets on this page); 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.

Other listings under the same name

Not linked to this profile — a second identifier (same issuer, same sponsor group) was not found. Could be the same person or a different one.
