The short version

Mark Luecke is listed as an executive officer and director on 8 SEC Form D filings by 5 issuers between Mar 2010 and May 2025: Prairie Aquatech Manufacturing, LLC (Sioux Falls, SD — manufacturing — 2020–2025; $16M reported sold to 15 investors), South Dakota Innovation Fund I Limited Partnership (Brookings, SD — industry reported as "Other" — 2010; $500K reported sold to 1 investors), Prairie Aqua Tech Investments, LLC (Sioux Falls, SD — pooled investment fund — 2017), NOVITA, LLC (Brookings, SD — industry reported as "Other" — 2014) and DAST, LLC (Sioux Falls, SD — other technology — 2014).

What this means A repeat sponsor — 5 separate companies raised money with this person listed as executive officer and director, over about 15 years. Across those companies the filings report $16.5M sold in total.

Listed alongside Larry Thornton (3 shared filings), BRUCE JAMERSON (1 shared filing), Bill Gibbons (1 shared filing), DONALD ENDRES (1 shared filing), DUANE GILLIAM (1 shared filing) 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.

The issuers belong to 2 sponsor groups: Harmony (8 issuers, $18.3M reported sold, 2010–2025) and Bird Dog (17 issuers, $9.45M reported sold, 2010–2026).

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), SEC enforcement releases, state securities regulators (AZ, CA, DE, TX, WA) — 9 court cases matching the name, 1 bankruptcy case matching the name listed in Key records below.

What this means 10 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 8 public filings for Mark Luecke and found 6 differences, 1 worth asking the sponsor about: Form D filed 165 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

6 differences found between the filings for Mark Luecke — 1 worth asking about (compared 8 filings on Oct 24, 2026)

Worth asking · Dec 13, 2024 – May 27, 2025

Form D filed 165 days after the first sale — Prairie Aquatech Manufacturing, LLC

The filing says the first sale was Dec 13, 2024. The Form D was filed May 27, 2025 — 165 days later. The rule: a Form D is generally due within 15 days after the first sale, so this one is 150 days past that.

What this means A late notice is common and carries no penalty by itself. It is worth asking the sponsor why the paperwork lagged.

The filing says the first sale was Jun 30, 2022. The Form D was filed Jul 18, 2022 — 18 days later. The rule: a Form D is generally due within 15 days after the first sale, so this one is 3 days past that.

Mark Luecke's role changed at Prairie Aquatech Manufacturing, LLC: executive officer → executive officer, director

The Jul 18, 2022 filing lists Mark Luecke as executive officer; the May 27, 2025 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.

No amendment in the last 12 months on an offering that may still be open — Prairie Aquatech Manufacturing, LLC (latest filing Jul 18, 2022)

The latest filing for this offering is dated Jul 18, 2022 (first sale Jun 30, 2022). It reports $1,984,207 sold of $12,700,000 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.

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).

Deals 5
