Listed alongside John Seaberg (12 shared filings), Greg Maurer (8 shared filings), James Baumgardt (8 shared filings), Jack K Ahrens (7 shared filings), Kyle Salyers (6 shared filings) and 20 others.

What this means These are the other officers, directors or promoters the companies named on the same forms — the team around John. Each name links to their own page.

The issuers belong to 2 sponsor groups: Phraxis (2 issuers, $9.85M reported sold, 2010–2023) and Lumen (2 issuers, $1.17M reported sold, 2009–2025).

What this means This person is listed across more than one sponsor team; each group page shows that team's full track record.

Public records searched: federal courts (CourtListener / RECAP), state securities regulators (AZ, CA, DE, TX, WA) — 1 court case matching the name listed in Key records below. Not yet searched: SEC enforcement releases.

What this means 1 record came back. Each one is listed below with a link to the original document and a line saying why it matched. A name match is not proof it is the same person or company — read the why line and the document. Being sued or named in a release is an accusation, not a finding.

Key records

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

same rare surname (2 people in Form D filings, 7 federal dockets); surname only in the caption; court in FL (not a filing state)

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, 2:18 AM ET.

Court records show docket facts only; we never restate allegations as facts. Outcome wording comes from the docket feed; where it does not state a disposition we say so.

State courts: not yet searched. No state offers a lawful automated statewide source PartnerFacts can use today. 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. Federal courts are searched through CourtListener / RECAP.

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).
