The short version

Mink Brook is a sponsor group of 2 issuers that PartnerFacts links to one sponsor (shared people, shared management entity, same business address, similar issuer names; automatic match from the filings), filing 23 Form D filings between Apr 2019 and Jan 2026.

What this means One team, 2 deal companies, about 7 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: $122.9M to 24 investors (latest filing per issuer). Industries as reported: Pooled Investment Fund (2). Issuers are based in FL (2).

What this means $122.9M raised across the group, about $5.12M per investor. Amounts come from each company's latest Form D; they are what the sponsor reported, not audited figures.

Principal people: Mink Brook Christopher Capital GP (2 issuers, promoter, entity) and William Christopher Mueller (2 issuers, executive officer and promoter).

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

Activity: 0 new offerings in the last 12 months; latest filing Jan 8, 2026.

What this means No new raise filed in the past 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) — 1 bankruptcy case matching the name listed in Key records below.

What this means 1 record 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 23 public filings for Mink Brook and found 8 differences, 2 worth asking the sponsor about: Mink Brook Christopher Capital GP is no longer listed on the May 31, 2024 amendment; Mink Brook Christopher Capital GP is no longer listed on the Dec 19, 2023 amendment; 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.

8 differences found between the filings for Mink Brook — 2 worth asking about (compared 23 filings on Oct 24, 2026)

Worth asking · Dec 13, 2021 – May 31, 2024

Mink Brook Christopher Capital GP is no longer listed on the May 31, 2024 amendment — Mink Brook Partners LP

Mink Brook Christopher Capital GP appears on the Dec 13, 2021 Form D/A (promoter) but not on the May 31, 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.

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.
