The short version

Sean McAlpine is listed as a promoter on 5 SEC Form D filings by 5 issuers between Jul 2021 and Dec 2022: Mid-Michigan Portfolio 9 LLC (Atlanta, GA — commercial — 2022; $14.1M reported sold to 134 investors), Mid-Michigan Manager Deal 3 LLC (Atlanta, GA — commercial — 2022; $2.35M reported sold to 23 investors), Mid-Michigan Manager Deal 2 LLC (Atlanta, GA — commercial — 2021; $1.48M reported sold to 11 investors), Mid-Michigan Dental Deal 1 LLC (Atlanta, GA — commercial — 2022; $500K reported sold to 6 investors) and Mid-Michigan Portfolio 8 LLC (Atlanta, GA — commercial — 2021).

What this means A repeat sponsor — 5 separate companies raised money with this person listed as promoter. Across those companies the filings report $18.5M sold in total.

Listed alongside Mark DeMonaco (5 shared filings), Salem VanderStel (5 shared filings), Steve Lyman (4 shared filings), Andrew Goldberger (3 shared filings) and Steven Lyman (1 shared filing).

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

All 5 issuers belong to the sponsor group Mid Michigan (15 issuers, $79.5M reported sold, 2019–2026).

What this means A sponsor group is one team that sets up a new company for each deal. Mid Michigan has 15 companies on file and $79.5M reported sold in total — the group page shows the whole track record in one place.

Public records searched: federal courts (CourtListener / RECAP), SEC enforcement releases, state securities regulators (AK, AL, AR, AZ, CA, CO, CT, DC, DE, FINRA, FL, GA, HI, ID, IL, KS, KY, LA, MA, MD, ME, MI, MO, MS, MT, NASAA, NC, ND, NH, NM, NV, NY, OH, OK, OR, PA, RI, SC, SD, TN, TX, UT, VT, WA, WI, WV, WY) — 1 bankruptcy case matching the name listed in Key records below.

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.

We compared 5 public filings for Sean McAlpine and found 5 differences, 1 worth asking the sponsor about: Sean McAlpine appears on 5 deals that stopped filing before reaching their target; 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.

Same name, different state: "Sean McAlpine" (A1) is a separate record

This page covers filings where the address state is MI. A separate record, "Sean McAlpine" with address state A1, is listed on 4 filings — most recently by ARGO GRAPHENE SOLUTIONS CORP. (Sep 28, 2026). The two records do not overlap in time: this page runs Jul 16, 2021 to Dec 6, 2022; the other runs Jun 17, 2026 to Sep 28, 2026.

What this means Could be the same person who moved, or two people with the same name. 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.

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).

Registrations and other filings

Business registration (state registry / Secretary of State)

Individuals are not matched to business registrations — registries list companies, and a name alone is not enough to tie a person to one. Officers and managers appear by name inside each matched company's record on the issuer pages. Registries searched: AL (Alabama Secretary of State — Business Entity Records (arc-sos.state.al.us), searched by issuer name, data as of Oct 24, 2026); CO (Colorado Secretary of State — Business Entities in Colorado (data.colorado.gov), data as of Oct 23, 2026); CT (Connecticut Secretary of the State — Business Registry (data.ct.gov), data as of Oct 24, 2026); FL (Florida Department of State, Division of Corporations — quarterly corporate data file (Sunbiz), data as of Oct 7, 2026); NY (New York Department of State — Corporations and Other Entities (data.ny.gov: All Filings + Active Corporations), data as of Oct 20, 2026); OR (Oregon Secretary of State — Active Businesses, All (data.oregon.gov), data as of Oct 20, 2026); PA (Pennsylvania Department of State — Registered Businesses, Current (data.pa.gov), data as of Oct 6, 2026); TX (Texas Comptroller — Active Franchise Taxpayers incl.
