The short version

William Hambrecht is listed as an executive officer, director, and promoter on 3 SEC Form D filings by 3 issuers between Apr 2015 and May 2021: Hambrecht Ducera Healthcare Growth Venture Fund II, LP (New York, NY — pooled investment fund — 2021; $25M reported sold to 1 investors), Hambrecht Ducera Healthcare Growth Venture Fund I, LP (New York, NY — pooled investment fund — 2019; $25M reported sold to 1 investors) and WR Hambrecht Ventures III, L.P. (San Francisco, CA — pooled investment fund — 2015; $5M reported sold to 18 investors).

What this means A repeat sponsor — 3 separate companies raised money with this person listed as executive officer, director, and promoter, over about 6 years. Across those companies the filings report $55M sold in total.

Listed alongside Thomas Thurston (3 shared filings), Elizabeth Hambrecht (2 shared filings), Michael Kramer (2 shared filings) and John Paul Hullar (1 shared filing).

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 3 issuers belong to the sponsor group Hambrecht Ducera Healthcare (3 issuers, $55M reported sold, 2015–2021).

What this means A sponsor group is one team that sets up a new company for each deal. Hambrecht Ducera Healthcare has 3 companies on file and $55M 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) — 1 state regulator order, 1 bankruptcy case matching the name listed in Key records below.

What this means 2 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 3 public filings for William Hambrecht and found 9 differences: William Hambrecht appears on 1 deal that stopped filing before reaching its target; Form D filed 19 days after the first sale; 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

9 differences found between the filings for William Hambrecht (compared 3 filings on Oct 24, 2026)

Note · Apr 24, 2015

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

WR Hambrecht Ventures III, L.P. (last filing Apr 24, 2015; $5,005,000 sold of $20,000,000). 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.

Note · Dec 21, 2018 – Jan 9, 2019

Form D filed 19 days after the first sale — Hambrecht Ducera Healthcare Growth Venture Fund I, LP

The filing says the first sale was Dec 21, 2018. The Form D was filed Jan 9, 2019 — 19 days later. The rule: a Form D is generally due within 15 days after the first sale, so this one is 4 days past that.

What this means A late notice is common and carries no penalty by itself. It is worth asking the sponsor why the paperwork lagged.

The latest filing for this offering is dated May 24, 2021 (first sale May 11, 2021). It reports $25,000,000 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.

listed as "William Robert Hambrecht" on the Apr 24, 2015 filing, and "William Hambrecht" on 2 filings (from Jan 9, 2019).

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.

What this means Two records with one name were active at the same time. That can be one person listing different company addresses, or two different people. 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. As of Oct 24, 2026.

"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); KY (Kentucky Secretary of State — Business Entity Search (sosbes.sos.ky.gov), searched by issuer name, data as of Oct 24, 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.

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)

None of the 3 issuers this person is listed on appears in Form ADV (searched 24,962 advisers as of Oct 2, 2026). A person is never an adviser firm; Form ADV is checked for the issuers and the management companies they are listed with.
