Key records

Five things investors ask first. Items still in human review are counted, not shown.

1. Lawsuits

None found in sources searched

What was searched

Sources searched: CourtListener bulk data (RECAP dockets as of 2026-09-30; recall-first rule 10-24) — federal district + bankruptcy courts; live RECAP re-check pending. State courts: not yet searched. PACER: not searched. · Last checked Oct 24, 2026, 2:35 AM ET.

Texas (re:SearchTX) terms prohibit storing results in a database open to third parties; New York (WebCivil) and Massachusetts (MassCourts) require a browser check that blocks scripted queries; California has no statewide index (58 county portals; Rule of Court 2.503 grants name-based access case by case); Florida, Utah and Illinois offer paid or partial access whose terms for automated use are unverified. Washington (dw.courts.wa.gov; bulk index reports under a JISC data-dissemination agreement), Delaware (CourtConnect; Court of Chancery not included) and Arizona (apps.azcourts.gov/publicaccess, which has an official channel to request high-volume access) are the candidates; PartnerFacts will request written permission before any automated search.

4. Differences between public sources

Not made for individual people — comparisons cover issuers and sponsor groups

5. Money to insiders

0 of 2 offerings report sales commissions; 0 report finder's fees; 1 reports proceeds to related persons totalling $270,000. (includes amounts the issuer reported as estimates)

Offering (latest filing)	Sales commissions	Finder's fees	To insiders	Paid to sell it	Source
Nov 6, 2018 D Autonomous Marine Systems, Inc. File 021-325149	$0	$0	$0	None listed on this filing	EDGAR ↗
Sep 19, 2017 D/A Autonomous Marine Systems, Inc. File 021-258305	$0	$0	$270,000 (est.)	None listed on this filing	EDGAR ↗

How this is counted

Counts come from Form D Items 12–15 on the filings in our index (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).
