John B. Henneman is listed as a director on 1 SEC Form D filing by 1 issuer in Dec 2025: Aprea Therapeutics, Inc. (Doylestown, PA — biotechnology — 2025; $3.06M reported sold to 8 investors).

What this means One deal on file with the SEC, filed Dec 2025. A Form D is the notice a company files after it starts selling a private investment — it is a notice, not an approval.

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.

Public records searched: federal courts (CourtListener / RECAP), state securities regulators (AZ, CA, DE, TX, WA) — 1 bankruptcy 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.

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).
