The short version

William E. Aaron is listed as an executive officer on 36 SEC Form D filings by 4 issuers between Oct 2009 and Dec 2018: HAMPSHIRE ASSOCIATES FUND, L.P. (New York, NY — pooled investment fund — 2009–2018; $118.3M reported sold to 191 investors), Hampshire Associates Fund QP, L.P. (New York, NY — pooled investment fund — 2009–2018; $89M reported sold to 66 investors), HAMPSHIRE INSTITUTIONAL FUND, L.P. (New York, NY — pooled investment fund — 2009–2018; $87.9M reported sold to 157 investors) and Praesidio Low Volatility Fund, LP (New York, NY — pooled investment fund — 2012–2017; $40.7M reported sold to 29 investors).

What this means A repeat sponsor — 4 separate companies raised money with this person listed as executive officer, over about 9 years. Across those companies the filings report $336.1M sold in total.

Listed alongside David Aaron (36 shared filings), SAGE Advisors, LLC (24 shared filings, management entity), Thomas O'Brien (18 shared filings), Michael Stein (17 shared filings), Lloyd Abramowitz (15 shared filings) and 4 others.

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

All 4 issuers belong to the sponsor group Hampshire (7 issuers, $363.3M reported sold, 2009–2026).

What this means A sponsor group is one team that sets up a new company for each deal. Hampshire has 7 companies on file and $363.3M 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, 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) — 5 bankruptcy cases matching the name listed in Key records below.

What this means 5 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 36 public filings for William E. Aaron and found 10 differences, 1 worth asking the sponsor about: 4 people are no longer listed on a later 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.

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).

Registrations and other filings

Business registration (state registry / Secretary of State)

Individuals are not matched to business registrations — registries list companies, and a name alone is not enough to tie a person to one. Officers and managers appear by name inside each matched company's record on the issuer pages. 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).

Adviser registration (Form ADV)

A person is never an adviser firm. 4 of the 4 issuers this person is listed on match a Form ADV adviser (searched 24,962 advisers as of Oct 2, 2026): HAMPSHIRE INSTITUTIONAL FUND, L.P., Hampshire Associates Fund QP, L.P., HAMPSHIRE ASSOCIATES FUND, L.P., Praesidio Low Volatility Fund, LP.

Other offering types (Regulation A and Regulation Crowdfunding)

Searched SEC Regulation A Data Sets (Forms 1-A, 1-K, 1-Z; 2015 Q2 → 2026 Q3); SEC Crowdfunding Offerings Data Sets (Form C family; 2016 Q2 → 2026 Q3); EDGAR form index for 2026 Q3 → 2026 Q4 (51,358 records as of Oct 23, 2026, 8:41 PM ET) — nothing matched this name.

Property records none — individuals are not matched

Property records are matched to companies only, never to individuals, so none are matched to William E. Aaron by design. Searched property records in Hillsborough County FL (Clerk recorded-document index Oct 14, 2026 to Oct 15, 2026 + FL DOR 2026 ownership roll), Miami-Dade County FL (FL DOR 2026 ownership roll), Harris County TX (HCAD 2026 ownership roll), Dallas County TX (DCAD 2026 ownership roll), New York City ACRIS documents and PLUTO ownership rows already retrieved for other issuers, Cook County IL sale and ownership rows already retrieved for other issuers (814,874 records as of Oct 23, 2026, 8:59 PM ET) for the 4 issuers this person is listed on — nothing matched.
