The short version

Brian Neumann is listed as a director on 15 SEC Form D filings by 13 issuers between Dec 2025 and Apr 2026. Largest by amount reported sold: Arrowstreet Capital Global All Country Alpha Extension Fund (Cayman) Ltd (Boston, MA — pooled investment fund — 2026; $19.27B reported sold to 399 investors), Arrowstreet Capital Global Equity Alpha Extension Fund Ltd (Boston, MA — pooled investment fund — 2026; $6.34B reported sold to 58 investors), Arrowstreet Capital Global Equity Long/Short Fund (Feeder) Ltd (Boston, MA — pooled investment fund — 2026; $3.42B reported sold to 138 investors), Arrowstreet ACWI Alpha Extension Fund V (Cayman) Ltd (Boston, MA — pooled investment fund — 2026; $2.82B reported sold to 26 investors), Arrowstreet ACWI Alpha Extension Fund III (Cayman) Ltd (Boston, MA — pooled investment fund — 2026; $2.39B reported sold to 8 investors) and 8 more (all listed below).

What this means That is a lot of deals — 13 separate companies raised money with this person listed as director. Across those companies the filings report $38.8B sold in total.

Listed alongside Carl O'Sullivan (15 shared filings), Letitia Solomon (15 shared filings) and Limited Partnership Arrowstreet Capital (15 shared filings).

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

All 13 issuers belong to the sponsor group Arrowstreet (54 issuers, $115.12B reported sold, 2010–2026).

What this means A sponsor group is one team that sets up a new company for each deal. Arrowstreet has 54 companies on file and $115.12B 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 (AK, AL, AR, AZ, CA, CT, DE, FINRA, GA, HI, ID, IL, KS, KY, LA, MA, MD, ME, MI, MO, MS, MT, NASAA, NC, ND, NH, NM, NV, OK, OR, PA, RI, SC, SD, TN, TX, VT, WA, WI, WV, WY) — 13 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 15 public filings for Brian Neumann and found 2 differences: Same name, different state: "Brian Neumann" (AZ) is a separate record; Address moved from Boston, MA to Grand Cayman, Cayman Islands (as filed: E9).

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

2 differences found between the filings for Brian Neumann (compared 15 filings on Oct 24, 2026)

Note · Sep 16, 2022

Same name, different state: "Brian Neumann" (AZ) is a separate record

This page covers filings where the address state is E9. A separate record, "Brian Neumann" with address state AZ, is listed on 1 filing — most recently by Yerbae Brands Co., Inc. (Sep 16, 2022). The two records do not overlap in time: this page runs Dec 31, 2025 to Apr 30, 2026; the other has one filing dated Sep 16, 2022.

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.

What this means Businesses move; this just shows the two places and dates. If you were told one city and the forms say another, ask which is current.

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).
