The short version

Mark Hilz is listed as an executive officer and director on 15 SEC Form D filings by 2 issuers between Jun 2014 and Dec 2023: Heart Test Laboratories, Inc. (Southlake, TX — other health care — 2015–2023; $6.49M reported sold to 50 investors) and MobileTREC Corp (Grapevine, TX — other technology — 2014; $545K reported sold to 14 investors).

What this means 2 separate companies raised money with this person listed as executive officer and director, over about 9 years. Across those companies the filings report $7.04M sold in total.

Listed alongside Andrew Simpson (10 shared filings), Brian Szymczak (9 shared filings), Bruce Bent (4 shared filings), Danielle Watson (4 shared filings), David R. Wells (4 shared filings) and 11 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) — 7 court cases matching the name, 1 bankruptcy case matching the name listed in Key records below.

What this means 8 records came back, including 1 court case 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 15 public filings for Mark Hilz and found 9 differences, 2 worth asking the sponsor about: Amount sold went down between filings; 8 Form Ds were filed more than 15 days after the first sale; 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

9 differences found between the filings for Mark Hilz — 2 worth asking about (compared 15 filings on Oct 24, 2026)

Worth asking · Dec 4, 2023 – Dec 7, 2023

Amount sold went down between filings — Heart Test Laboratories, Inc.

The Dec 4, 2023 filing says $1,585,006 sold; the Dec 7, 2023 Form D/A says $1,085,006 sold — $500,000 less.

What this means Amounts sold normally only go up as a raise continues. A drop can mean investors were refunded, a figure was corrected, or an earlier number was wrong. Ask the sponsor which it was.

What this means Late notices are common and carry no penalty by themselves. A pattern of late paperwork is worth asking the sponsor about.

Mark Hilz's role changed at Heart Test Laboratories, Inc.: executive officer → executive officer, director

The Dec 28, 2021 filing lists Mark Hilz as executive officer; the Sep 20, 2023 Form D lists executive officer, director.

What this means Roles on Form D are self-reported by the issuer. A change can mean a real change in who runs the company, or just a different box ticked. Ask who makes decisions today.

The Dec 4, 2023 filing says $1,585,006 offered; the Dec 7, 2023 Form D/A says $1,085,006.

What this means The target raise got smaller. That can mean the plan shrank or the sponsor stopped early. Ask what changed in the deal.

(latest filing Dec 11, 2019) · No amendment in the last 12 months on an offering that may still be open — Heart Test Laboratories, Inc. (latest filing Dec 11, 2019) · and 2 more

Mark Hilz is written 2 different ways on the filings

listed as "Mark Hilz" on 10 filings (from Jun 13, 2014), and "Mark Thomas Hilz" on 5 filings (from Jul 17, 2015).

What this means Same person, written differently — a middle name or suffix left off, or spelled another way. It is normal, but check that the full legal name matches your subscription documents.

What this means The issuer described its business differently on different forms. Often it is just a different box ticked; sometimes the deal itself changed. Ask which business your money is in.

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.

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).
