WILLIAM BRIAN OLSON is listed as an executive officer and director on 20 SEC Form D filings by 1 issuer between Aug 2009 and Jul 2015: QUANTUM FUEL SYSTEMS TECHNOLOGIES WORLDWIDE, INC. (Lake Forest, CA — manufacturing — 2009–2015; $12.3M reported sold to 264 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 CARL E SHEFFER (20 shared filings), G. Scott Samuelsen (20 shared filings), KENNETH R LOMBARDO (20 shared filings), Paul Grutzner (20 shared filings), BRADLEY J TIMON (19 shared filings) and 11 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) — 4 bankruptcy cases matching the name listed in Key records below.
What this means 4 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.

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.

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.

Raised $12.3M from 264 investors (100% of the $2M target) as of the latest filing. William is listed as executive officer, director on 20 filings for this deal.
