The short version

Pin Oak is a sponsor group of 19 issuers that PartnerFacts links to one sponsor (shared people, similar issuer names; automatic match from the filings), filing 78 Form D filings between Nov 2011 and Apr 2026.

What this means One team, 19 deal companies, about 15 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: $371.2M to 1,347 investors (latest filing per issuer). Industries as reported: Pooled Investment Fund (19). Issuers are based in TX (19).

What this means $371.2M raised across the group, about $276K per investor. Amounts come from each company's latest Form D; they are what the sponsor reported, not audited figures.

Principal people: Barrett Rouse (19 issuers, promoter), Douglas Schnitzer (1 issuer, promoter) and Griffin Guthneck (1 issuer, promoter).

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 Apr 23, 2026.

What this means Busy — still raising money this year.

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), property records (NYC, FL, IL and TX counties) — 7 court cases matching the name, 6 bankruptcy cases matching the name listed in Key records below.

What this means 13 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 the newest 50 of 78 public filings for Pin Oak and found 12 differences, 4 worth asking the sponsor about: 4 bankruptcy cases name the subject or team members; Amount sold went down between filings; 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.

Amount sold went down between filings — Pin Oak Opportunity Fund II Master, LP

What this means Amounts sold normally only go up as a raise continues. A drop can mean investors were refunded, a figure was corrected, or an earlier number was wrong. Ask the sponsor which it was.

Member companies were formed in 2 different states

Texas (18), Delaware (1) — out of 19 member issuers. The odd ones out: Pin Oak Premier Select Fund, LP (Delaware).

What this means Sponsors often form each deal company in Delaware or Wyoming no matter where the property is. A mix is common; it just tells you which state's rules each company lives under.

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. We compared the newest 50 of 78 filings (work cap); older filings are not covered here. 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 all 19 issuers in this group — every filing in our index, latest filing per offering (SEC file number).

Business registration (state registry / Secretary of State)

14 of 19 issuers have a matched state registry record — records by status: active 13 · status not stated 1.

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. Secretary of State file data (data.texas.gov), data as of Oct 24, 2026). Registries of other states have not been searched: many publish no bulk file and require a CAPTCHA or bot challenge on their search page, which we do not bypass (Delaware, for example, offers no public bulk file). A registry listing is the state's own record of the entity; it says nothing about the offering itself.
