The short version

William Byrnes is listed as a director on 1 SEC Form D filing by 1 issuer in Apr 2009: LoopNet, Inc. (San Francisco, CA — other technology — 2009; $50M reported sold to 8 investors).

What this means One deal on file with the SEC, filed Apr 2009. 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 Brent Stumme (1 shared filing), Dennis Chookaszian (1 shared filing), James T. Farrell (1 shared filing), Jason Greenman (1 shared filing), Noel J. Fenton (1 shared filing) and 5 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) — 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 1 public filing for William Byrnes and found 2 differences, 1 worth asking the sponsor about: Bankruptcy case: William J. Byrnes; 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.

Note · Sep 3, 2009 – Mar 3, 2014

Same name, different state: "William L. Byrnes" (MA) is a separate record

This page covers filings where the address state is CA. A separate record, "William L. Byrnes" with address state MA, is listed on 25 filings — most recently by FMR LLC (Mar 3, 2014). The two records do not overlap in time: this page has one filing dated Apr 23, 2009; the other runs Sep 3, 2009 to Mar 3, 2014.

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.

Sources
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
