The short version

William Clark is listed as a director on 2 SEC Form D filings by 1 issuer between May 2025 and Jan 2026: iBio, Inc. (San Diego, CA — biotechnology — 2025–2026; $26M reported sold to 52 investors).

What this means One deal on file with the SEC. A Form D is the notice a company files after it starts selling a private investment — it is a notice, not an approval.

Listed alongside Antonio Parada (2 shared filings), David Arkowitz (2 shared filings), Evert Shimmelpennink (2 shared filings), Felipe Duran (2 shared filings), Gary Sender (2 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.

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) — 5 SEC releases, 1 state regulator order listed in Key records below.

What this means 6 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 2 public filings for William Clark and found 7 differences, 1 worth asking the sponsor about: Regulator action: Global Finance & Investments, Inc., Charles R. Davis, Lucre Fund, LLC, JTA Enterprises, William H. Clark, Level Par Investments, LLC, Kelly G. Rogers, Sterling Meridian LLC, Ronald J. Linn Glenn Maske and William F. Dippolito, Defendants, and USAssets & Funding Corp., Nevada Sentry Service Corp., Wells Ventures LLC, Triquestra Management Corp., and CMR Mngt. Group, LLC, Relief Defendants (Jul 18, 2007); 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.

5. Money to insiders

2 of 2 offerings report sales commissions totalling $1,777,000; 0 report finder's fees; 0 report proceeds to related persons. (includes amounts the issuer reported as estimates)

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).
