The short version

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

5 of the issuers belong to the sponsor group Turning Rock (14 issuers, $1.37B reported sold, 2017–2026).

What this means A sponsor group is one team that sets up a new company for each deal. Turning Rock has 14 companies on file and $1.37B 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) — 4 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 12 public filings for David Markus and found 3 differences: No amendment in the last 12 months on an offering that may still be open; David Markus is listed with 2 different address states: IL, NY; 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

3 differences found between the filings for David Markus (compared 12 filings on Oct 24, 2026)

Note · Aug 17, 2023 – Aug 29, 2025

No amendment in the last 12 months on an offering that may still be open — Turning Rock Fund III LP (latest filing Aug 29, 2025)

The latest filing for this offering is dated Aug 29, 2025 (first sale Aug 17, 2023). It reports $505,161,788 sold of $600,000,000 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 · Oct 22, 2019 – Oct 31, 2019

No amendment in the last 12 months on an offering that may still be open — HENRY FERTILIZER HOLDINGS, LLC (latest filing Oct 31, 2019)

The latest filing for this offering is dated Oct 31, 2019 (first sale Oct 22, 2019). It reports $0 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 · Oct 31, 2019 – Oct 1, 2026

David Markus is listed with 2 different address states: IL, NY

IL on 1 filing (Oct 31, 2019); NY on 11 filings (Aug 31, 2023 to Oct 1, 2026).

What this means The address on a Form D is usually the company's, not the person's home, so this often just reflects different companies. It can also mean a move. Nothing wrong by itself.

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.

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.
