Data last updated Oct 23, 2026, 5:45 PM ET · Courts (RECAP) last checked: Oct 24, 2026, 2:25 AM ET · SEC enforcement last checked: covered by the index scan as of Oct 24, 2026, 2:50 AM ET

The short version

Mark Maciejewski is listed as a director on 3 SEC Form D filings by 1 issuer between Oct 2011 and Sep 2014: LoneStar Heart, Inc. (Irvine, CA — other health care — 2011–2014; $10.2M reported sold to 11 investors).

What this means One deal on file with the SEC. 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 Frank Ahmann (3 shared filings), Hugh Neuharth (3 shared filings), Olav B. Bergheim (3 shared filings), Raymond W. Cohen (3 shared filings), ANDREW COATS (2 shared filings) and 2 others.

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

Public records searched: federal courts (CourtListener / RECAP), SEC enforcement releases, state securities regulators (AZ, CA, DE, TX, WA) — 13 court cases matching the name, 13 bankruptcy cases matching the name listed in Key records below.

What this means 26 records came back, including 6 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 3 public filings for Mark Maciejewski and found 3 differences: No amendment in the last 12 months on an offering that may still be open; Same name, different state: "Mark Maciejewski" (HI or CA) is a separate record; 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

3 differences found between the filings for Mark Maciejewski (compared 3 filings on Oct 24, 2026)

Note · Nov 4, 2013 – Nov 18, 2013

No amendment in the last 12 months on an offering that may still be open — LoneStar Heart, Inc. (latest filing Nov 18, 2013)

The latest filing for this offering is dated Nov 18, 2013 (first sale Nov 4, 2013). It reports $2,396,585 sold of $12,750,009 offered. No later amendment is in our index as of Oct 24, 2026.

What this means SEC rules expect a yearly amendment while an offering is still going. The raise may simply have ended — a Form D does not say when it closed. Ask the sponsor whether the offering closed, when, and at what amount.

Note · Oct 25, 2012 – Jun 13, 2014

Same name, different state: "Mark Maciejewski" (HI or CA) is a separate record

This page covers filings where the address state is MN. A separate record, "Mark Maciejewski" with address state HI or CA, is listed on 4 filings — most recently by TruTag Technologies, Inc. (Sep 3, 2019). Both records have filings in the same period (Oct 25, 2012 to Jun 13, 2014).

What this means Two records with one name were active at the same time. That can be one person listing different company addresses, or two different people. We keep them apart until a filing ties them together. Check both pages before you decide.

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

None reported on 3 offerings — no sales commissions, finder's fees or proceeds to insiders

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.
