The short version

William Britain is listed as an executive officer, director, and promoter on 14 SEC Form D filings by 8 issuers between Aug 2010 and Jan 2026. Largest by amount reported sold: PetroCap Partners II, L.P. (Dallas, TX — pooled investment fund — 2014–2015; $350M reported sold to 80 investors), PetroCap Partners III, L.P. (Dallas, TX — pooled investment fund — 2018–2019; $300.3M reported sold to 21 investors), Falcon E&P Opportunities Fund, L.P.

(Dallas, TX — pooled investment fund — 2017; $50M reported sold to 9 investors) and 3 more (all listed below).

What this means A repeat sponsor — 8 separate companies raised money with this person listed as executive officer, director, and promoter, over about 16 years. Across those companies the filings report $989M sold in total.

Listed alongside Marc Manzo (11 shared filings), David Hopson (9 shared filings), John Sears (6 shared filings), PetroCap, LLC (6 shared filings, management entity), Richard D. Rinehart (6 shared filings) and 9 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 8 issuers belong to the sponsor group Petrocap (8 issuers, $989M reported sold, 2010–2026).

What this means A sponsor group is one team that sets up a new company for each deal. Petrocap has 8 companies on file and $989M 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) — 4 court cases matching the name, 1 state regulator order, 7 bankruptcy cases matching the name listed in Key records below.

What this means 12 records came back, including 1 court case still open — open cases can take years and cost money. 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 14 public filings for William Britain and found 10 differences: 13% of the money raised went to insiders; William Britain appears on 1 deal that stopped filing before reaching its target; 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

10 differences found between the filings for William Britain (compared 14 filings on Oct 24, 2026)

Note · Apr 29, 2014

13% of the money raised went to insiders — PetroCap Partners II, L.P.

The Apr 29, 2014 Form D reports $108,650,000 sold and $13,765,000 of the proceeds used for payments to officers, directors or promoters (marked as an estimate). Issuer's note: "Reimbursement of estimated organizational expenses and estimated aggregate amount of management fees for the first 3 years.".

What this means The filing reports how much of the money raised was paid to insiders. Over 10% is high for most deals. Ask what it paid for.

William Britain appears on 1 deal that stopped filing before reaching its target

Aplomado Partners I-A REIT, LLC (last filing Nov 10, 2022; $0 sold of $115,000). Each has no filing in more than two years and reported under half its target sold.

What this means An issuer whose last filing is more than two years old and reported under half its target sold. The raise may have closed early or quietly stopped. Ask what happened to each.

No amendment in the last 12 months on an offering that may still be open — PetroCap Partners III, L.P. (latest filing Apr 10, 2019)

The latest filing for this offering is dated Apr 10, 2019 (first sale Apr 12, 2018). It reports $300,250,000 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.

The Apr 29, 2014 filing says an indefinite amount offered; the Nov 12, 2014 Form D/A says $350,000,000.

What this means The target raise changed. Raising the cap is common when a deal grows; ask whether the extra money has the same terms and use.

listed as "William L. Britain" on 4 filings (from Aug 12, 2010), and "William Britain" on 10 filings (from Apr 29, 2014).

What this means Same person, written differently — a middle name or suffix left off, or spelled another way. It is normal, but check that the full legal name matches your subscription documents.

Same name, different state: "William Britain" (GA) is a separate record

This page covers filings where the address state is TX. A separate record, "William Britain" with address state GA, is listed on 3 filings — most recently by HireIQ Solutions, Inc. (Mar 2, 2011). The two records do not overlap in time: this page runs Apr 29, 2014 to Jan 15, 2026; the other runs Mar 31, 2010 to Mar 2, 2011.

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 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.

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).

Deals 8

Every issuer that named William Britain on a Form D, newest first. A Form D is the notice a company files after it starts selling a private investment.

One team, 8 deal companies. William Britain is listed on 8 of them.

Sources

Issuers are grouped when their Form D filings share related persons, a management entity or a business address (automatic match from the filings). "Listed" marks the issuers that name William Britain.

Same business address

51 other issuers file from the same address (first 50 shown)

A shared address can mean the same team, a shared office building or a registered agent. It is a lead, not a conclusion.

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 8 issuers this person is listed on match a Form ADV adviser (searched 24,962 advisers as of Oct 2, 2026): PetroCap Partners IV, L.P., Four Rivers Co-Invest, L.P., PetroCap Partners II, L.P., Falcon E&P Opportunities Fund, L.P..

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 Britain 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 8 issuers this person is listed on — nothing matched.
