The short version

Marc E. Sacks is listed as an executive officer and director on 33 SEC Form D filings by 12 issuers between Sep 2009 and Sep 2023. Largest by amount reported sold: Mesirow Financial Private Equity Fund VIII-A, L.P. (Chicago, IL — pooled investment fund — 2020–2022; $776.5M reported sold to 59 investors), Mesirow Financial Private Equity Fund VII-A, L.P. (Chicago, IL — pooled investment fund — 2017–2019; $618.5M reported sold to 37 investors), MESIROW FINANCIAL PRIVATE EQUITY PARTNERSHIP FUND VI, L.P. (Chicago, IL — pooled investment fund — 2010–2015; $613.9M reported sold to 32 investors), Mesirow Private Equity Fund IX, L.P. (Chicago, IL — pooled investment fund — 2023; $466.8M reported sold to 21 investors), MESIROW FINANCIAL PRIVATE EQUITY PARTNERSHIP FUND V, L.P. (Chicago, IL — pooled investment fund — 2009–2010; $465M reported sold to 25 investors) and 7 more (all listed below).

What this means That is a lot of deals — 12 separate companies raised money with this person listed as executive officer and director, over about 14 years. Across those companies the filings report $3.77B sold in total.

Listed alongside Thomas E. Galuhn (33 shared filings), Richard S. Price (32 shared filings), Kristie P. Paskvan (23 shared filings), Daniel P. Howell (22 shared filings), Dennis Black (22 shared filings) and 28 others.

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

All 12 issuers belong to the sponsor group Mesirow (36 issuers, $6.39B reported sold, 2009–2026).

What this means A sponsor group is one team that sets up a new company for each deal. Mesirow has 36 companies on file and $6.39B 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 (AZ, CA, DE, TX, WA) — none found.

What this means Nothing turned up where we looked (3 sources). That does not prove there is nothing — it means none was found in those sources on that date.

We compared 33 public filings for Marc E. Sacks and found 10 differences, 3 worth asking the sponsor about: Paid seller listed without a CRD number: AFK and Partners Asset Management Sarl; Paid seller listed without a CRD number: Greenstone Group FZC; 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.

10 differences found between the filings for Marc E. Sacks — 3 worth asking about (compared 33 filings on Oct 24, 2026)

Worth asking · May 25, 2022

Paid seller listed without a CRD number: AFK and Partners Asset Management Sarl — Mesirow Financial Private Equity Fund VIII-A, L.P.

AFK and Partners Asset Management Sarl is listed as receiving sales compensation on 1 filing (May 25, 2022) with no FINRA CRD number given.

What this means People paid to sell securities normally hold a FINRA registration with a CRD number. Without one we cannot look them up on BrokerCheck. Ask who they are and whether they are registered.

Marc E. Sacks is no longer listed on the Sep 20, 2024 amendment — Mesirow Private Equity Fund IX, L.P.

Marc E. Sacks appears on the Sep 6, 2023 Form D (director) but not on the Sep 20, 2024 Form D/A for the same offering.

What this means People leave, and the issuer must list only current officers, directors and promoters. It is still worth asking why this person left and who replaced them.

Note · Jun 29, 2012 – Jul 16, 2012

Form D filed 17 days after the first sale — MESIROW FINANCIAL PRIVATE EQUITY PARTNERSHIP FUND (CAYMAN FEEDER), L.P.

The filing says the first sale was Jun 29, 2012. The Form D was filed Jul 16, 2012 — 17 days later. The rule: a Form D is generally due within 15 days after the first sale, so this one is 2 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.

What this means Targets change as deals grow or shrink. Ask whether later money has the same terms.

(latest filing May 22, 2015) · and 4 more

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

Marc E. Sacks is written 2 different ways on the filings

listed as "Marc E Sacks" on 27 filings (from Sep 3, 2009), and "Marc Sacks" on 6 filings (from Nov 16, 2009).

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.

Industry group changed between filings — MESIROW FINANCIAL HOLDINGS INC

"Other Banking and Financial Services" (Sep 3, 2009); then "Other" (Sep 27, 2010 to Aug 4, 2014).

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.

Reported revenue range changed between filings — MESIROW FINANCIAL CAPITAL PARTNERS X LP

"Not Applicable" (Jan 20, 2010); then "Decline to Disclose" (Jan 11, 2011).

What this means This is the size band the issuer picks for itself on the form. A change can mean the business grew or shrank — or that it chose not to say. Ask for current numbers.

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 12

Every issuer that named Marc E. Sacks on a Form D, newest first. A Form D is the notice a company files after it starts selling a private investment.

Sources

Issuers are grouped when their Form D filings share related persons, a management entity or a business address (automatic match from the filings). "Listed" marks the issuers that name Marc E. Sacks.

Same business address

51 other issuers file from the same address (first 50 shown)

A shared address can mean the same team, a shared office building or a registered agent. It is a lead, not a conclusion.

Registrations and other filings

Adviser registration (Form ADV)

None of the 12 issuers this person is listed on appears in Form ADV (searched 24,962 advisers as of Oct 2, 2026). A person is never an adviser firm; Form ADV is checked for the issuers and the management companies they are listed with.

Other offering types (Regulation A and Regulation Crowdfunding)

Searched SEC Regulation A Data Sets (Forms 1-A, 1-K, 1-Z; 2015 Q2 → 2026 Q3); SEC Crowdfunding Offerings Data Sets (Form C family; 2016 Q2 → 2026 Q3); EDGAR form index for 2026 Q3 → 2026 Q4 (51,358 records as of Oct 23, 2026, 8:41 PM ET) — nothing matched this name.

Property records none — individuals are not matched

Property records are matched to companies only, never to individuals, so none are matched to Marc E. Sacks by design. Searched property records in Hillsborough County FL (Clerk recorded-document index Oct 14, 2026 to Oct 15, 2026 + FL DOR 2026 ownership roll), Miami-Dade County FL (FL DOR 2026 ownership roll), Harris County TX (HCAD 2026 ownership roll), Dallas County TX (DCAD 2026 ownership roll), New York City ACRIS documents and PLUTO ownership rows already retrieved for other issuers, Cook County IL sale and ownership rows already retrieved for other issuers (814,874 records as of Oct 23, 2026, 8:59 PM ET) for the 12 issuers this person is listed on — nothing matched.
