The short version

Cindy Guyon is listed as an executive officer on 1 SEC Form D filing by 1 issuer in Mar 2020: C6 Combustion Technologies, LP (Chicago, IL — manufacturing — 2020; $420K reported sold to 20 investors).

What this means One deal on file with the SEC, filed Mar 2020. A Form D is the notice a company files after it starts selling a private investment — it is a notice, not an approval.

Listed alongside Arthur Szefer (1 shared filing), Chris Reimer (1 shared filing), Ernst Bergen (1 shared filing) and Martin Jaszczuk (1 shared filing).

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

Public records searched: federal courts (CourtListener / RECAP), SEC enforcement releases, state securities regulators (AR, AZ, CA, CT, DE, FINRA, GA, HI, ID, LA, ME, MO, MS, MT, NASAA, NC, NH, NM, OR, RI, TX, WA) — 6 court cases matching the name, 8 bankruptcy cases matching the name listed in Key records below.

What this means 14 records came back, including 2 court cases still open — open cases can take years and cost money. 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.

We compared 1 public filing for Cindy Guyon and found 5 differences, 1 worth asking the sponsor about: Cindy Guyon is no longer listed on the Mar 2, 2021 amendment; and more below.

What this means These are differences between the sponsor's own SEC filings — both values, dates and sources are listed in Key records, section 4. Most have ordinary explanations; ask the sponsor.

4. Differences between public sources

Comparisons cover issuers and sponsor groups — see the issuer pages under Deals

5 differences found between the filings for Cindy Guyon — 1 worth asking about (compared 1 filing on Oct 24, 2026)

Note · Mar 11, 2020

20% of the money raised went to insiders — C6 Combustion Technologies, LP

The Mar 11, 2020 Form D/A reports $420,000 sold and $85,688 of the proceeds used for payments to officers, directors or promoters (marked as an estimate).

What this means The filing reports how much of the money raised was paid to insiders. Over 10% is high for most deals. Ask what it paid for.

Worth asking · Mar 11, 2020 – Mar 2, 2021

Cindy Guyon is no longer listed on the Mar 2, 2021 amendment — C6 Combustion Technologies, LP

Cindy Guyon appears on the Mar 11, 2020 Form D/A (executive officer) but not on the Mar 2, 2021 Form D/A for the same offering.

What this means People leave, and the issuer must list only current officers, directors and promoters. It is still worth asking why this person left and who replaced them.

What is compared

What is compared: every Form D and D/A we hold for this subject, side by side — filing dates vs. first-sale dates (the 15-day rule), amendment timing on open offerings (the yearly-amendment expectation), amounts sold, investor counts, offering amounts and minimums across amendments, industry and size bands, addresses, how each person's name and role is written, paid sellers' CRD numbers, and (for groups) where the member companies were formed and sit. Everything is as filed by the issuer; the SEC does not check it. Differences are common and usually have ordinary explanations — we show both values, the dates, and the source so you can ask. As of Oct 24, 2026.

5. Money to insiders

0 of 1 offering report sales commissions; 0 report finder's fees; 1 reports proceeds to related persons totalling $85,688. (includes amounts the issuer reported as estimates)

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).
