The short version

Mark A Radzik is listed as an executive officer, director, and promoter on 8 SEC Form D filings by 6 issuers between Nov 2017 and Oct 2026. Largest by amount reported sold: Granite Creek FlexCap III, L.P. (Chicago, IL — pooled investment fund — 2023; $102.6M reported sold to 63 investors), Granite Creek RBIC Agribusiness, L.P. (Chicago, IL — pooled investment fund — 2025–2026; $81.3M reported sold to 12 investors), Granite Creek FlexCap II, L.P. (Chicago, IL — pooled investment fund — 2017; $48.2M reported sold to 75 investors), Granite Creek Agribusiness I, LP (Chicago, IL — pooled investment fund — 2025–2026; $29.4M reported sold to 12 investors), Akita Credit Holdings, L.P. (Chicago, IL — investing — 2020; $29.4M reported sold to 8 investors) and 1 more (all listed below).

What this means A repeat sponsor — 6 separate companies raised money with this person listed as executive officer, director, and promoter, over about 9 years. Across those companies the filings report $298.2M sold in total.

Listed alongside James Clark (7 shared filings), Peter G Lehman (7 shared filings), BRIAN B. BOORSTEIN (5 shared filings), Granite Creek Capital Partners, L.L.C. (4 shared filings, management entity), GRANITE CREEK AGRIBUSINESS GP, LLC (2 shared filings, management entity) and 4 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.

All 6 issuers belong to the sponsor group Granite Creek (11 issuers, $326.8M reported sold, 2014–2026).

What this means A sponsor group is one team that sets up a new company for each deal. Granite Creek has 11 companies on file and $326.8M 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) — 2 court cases matching the name, 1 bankruptcy case matching the name listed in Key records below.

What this means 3 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 8 public filings for Mark A Radzik and found 6 differences: Form D filed 43 days after the first sale; No amendment in the last 12 months on an offering that may still be open; 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 A Radzik (compared 8 filings on Oct 24, 2026)

Note · Feb 19, 2026 – Apr 3, 2026

Form D filed 43 days after the first sale — GCCP KR Holding LLC

The filing says the first sale was Feb 19, 2026. The Form D was filed Apr 3, 2026 — 43 days later. The rule: a Form D is generally due within 15 days after the first sale, so this one is 28 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.

Sources
Note · Jan 4, 2023 – Jan 10, 2023

No amendment in the last 12 months on an offering that may still be open — Granite Creek FlexCap III, L.P. (latest filing Jan 10, 2023)

The latest filing for this offering is dated Jan 10, 2023 (first sale Jan 4, 2023). It reports $102,600,000 sold of an indefinite amount 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.

Sources
Note · Jun 26, 2020 – Jul 8, 2020

No amendment in the last 12 months on an offering that may still be open — Akita Credit Holdings, L.P. (latest filing Jul 8, 2020)

The latest filing for this offering is dated Jul 8, 2020 (first sale Jun 26, 2020). It reports $29,350,000 sold of $35,000,000 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.

Sources
Note · Nov 10, 2017 – Nov 20, 2017

No amendment in the last 12 months on an offering that may still be open — Granite Creek FlexCap II, L.P. (latest filing Nov 20, 2017)

The latest filing for this offering is dated Nov 20, 2017 (first sale Nov 10, 2017). It reports $48,179,000 sold of $75,000,000 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.

Sources
Note · Nov 20, 2017 – Apr 3, 2026

Mark A Radzik is written 2 different ways on the filings

listed as "Mark A. Radzik" on 7 filings (from Nov 20, 2017), and "Mark Radzik" on the Apr 3, 2026 filing.

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
Note · Aug 6, 2009

Same name, different state: "Mark Radzik" (FL) is a separate record

This page covers filings where the address state is IL. A separate record, "Mark Radzik" with address state FL, is listed on 1 filing — most recently by TMS Inc (Aug 6, 2009). The two records do not overlap in time: this page runs Nov 20, 2017 to Oct 2, 2026; the other has one filing dated Aug 6, 2009.

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.

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.

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).
