The short version

Mack is a sponsor group of 9 issuers that PartnerFacts links to one sponsor (shared people, shared management entity, same business address, similar issuer names; automatic match from the filings), filing 14 Form D filings between Mar 2021 and Sep 2026.

What this means One team, 9 deal companies, about 5 years of track record in SEC filings. We link the companies because the same people or address appear on their forms — tap "Request a correction" if that is wrong.

Combined reported sold: $41.1M to 192 investors (latest filing per issuer). Industries as reported: "Other" (9). Issuers are based in TX (9).

What this means $41.1M raised across the group, about $214K per investor. Amounts come from each company's latest Form D; they are what the sponsor reported, not audited figures.

Principal people: Roszell Mack III (9 issuers, executive officer), Mack & Co. GP LLC (7 issuers, executive officer and director, entity) and Mack & Co., LLC (3 issuers, executive officer and director, entity).

What this means The person on the most companies is usually the one running the show; their page lists every deal.

Activity: 3 new offerings in the last 12 months; latest filing Sep 16, 2026.

What this means Busy — still raising money this year.

Public records searched: federal courts (CourtListener / RECAP), SEC enforcement releases, state securities regulators (AZ, CA, DE, TX, WA), property records (NYC, FL, IL and TX counties) — 2 court cases matching the name, 2 bankruptcy cases matching the name listed in Key records below.

What this means 4 records 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 14 public filings for Mack and found 6 differences, 1 worth asking the sponsor about: 8 paid sellers are listed without a CRD number; 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

No comparisons published

What is compared

No public statement by this sponsor group has been collected yet, so there is nothing to compare. Sources compared: the sponsor's own website (known from the issuer's own filings — Form C issuer website, EDGAR company profile — an approved profile claim or Form ADV Item 1.I of its matched adviser) · SEC Form D · SEC Form ADV (IAPD) · Internet Archive · No website is on file for this sponsor group yet.

6 differences found between the filings for Mack — 1 worth asking about (compared 14 filings on Oct 24, 2026)

Worth asking · Mar 26, 2021 – Dec 16, 2024

8 paid sellers are listed without a CRD number

Paid seller listed without a CRD number: Salem Jeiroudi — Begin Mack LP · Paid seller listed without a CRD number: Jesus Casado — Begin Mack LP · Paid seller listed without a CRD number: Jesus Casado — Strateos Mack LP · Paid seller listed without a CRD number: Salem Jeiroudi — Strateos Mack LP · Paid seller listed without a CRD number: Jesus Casado — UMT Mack LP · and 3 more

What this means Without a CRD number we cannot look a seller up on BrokerCheck. Ask who they are and whether they are registered.

Sources
Note · Jan 31, 2024 – Sep 16, 2026

5 Form Ds were filed more than 15 days after the first sale

Form D filed 22 days after the first sale — Wonder Mack Excalibur LP · Form D filed 17 days after the first sale — Skan AI Mack LP · Form D filed 17 days after the first sale — Wonder Mack LP · Form D filed 21 days after the first sale — Wonder Mack LP · Form D filed 23 days after the first sale — Mack & Co. Equity Partners LP

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

Sources
Note · Nov 7, 2023 – Dec 16, 2024

Offering amount changed between filings — Begin Mack LP

The Nov 7, 2023 filing says $3,850,000 offered; the Dec 16, 2024 Form D/A says $4,100,000.

What this means The target raise changed. Raising the cap is common when a deal grows; ask whether the extra money has the same terms and use.

Sources
Note · Dec 30, 2021 – Mar 29, 2024

5 offerings have no amendment in the last 12 months and may still be open

No amendment in the last 12 months on an offering that may still be open — Voyager Mack LP (latest filing Mar 29, 2024) · No amendment in the last 12 months on an offering that may still be open — Mack & Co. Equity Partners LP (latest filing Feb 23, 2024) · No amendment in the last 12 months on an offering that may still be open — UMT Mack LP (latest filing Dec 23, 2022) · No amendment in the last 12 months on an offering that may still be open — TH Mack LP (latest filing Jan 14, 2022) · No amendment in the last 12 months on an offering that may still be open — TH Mack LP (latest filing Jan 14, 2022)

What this means SEC rules expect a yearly amendment while an offering is still going. Ask the sponsor which of these raises have closed.

Sources
Note · Mar 26, 2021 – Dec 23, 2022

Roszell Mack III is written 2 different ways on the filings

listed as "Roszell Mack III" on 6 filings (from Mar 26, 2021), and "Roszell Mack" on 8 filings (from Dec 23, 2022).

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.

Sources
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

8 of 13 offerings report sales commissions totalling $4,712,193; 6 report finder's fees totalling $1,542,320; 0 report proceeds to related persons. (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 all 9 issuers in this group — every filing in our index, latest filing per offering (SEC file number).

Computed by PartnerFacts from SEC EDGAR Form D data as of Oct 23, 2026, 5:45 PM ET. Rows without a range: fewer than 30 comparable filings, or not a Rule 506 offering. No ranking or score.
