The short version

William Newell is listed as an executive officer and director on 11 SEC Form D filings by 5 issuers between Jul 2015 and Apr 2020: SutroVax, Inc. (Foster City, CA — biotechnology — 2015–2020; $110M reported sold to 23 investors), SUTRO BIOPHARMA INC (South San Francisco, CA — biotechnology — 2018; $85.4M reported sold to 15 investors), Symic Holdings, LLC (Emeryville, CA — biotechnology — 2015–2017; $29.4M reported sold to 42 investors), Sapienco, Inc. (Redondo Beach, CA — other technology — 2016; $320K reported sold to 2 investors) and SparX Works, Inc. (Redondo Beach, CA — other technology — 2019; $437 reported sold to 6 investors).

What this means A repeat sponsor — 5 separate companies raised money with this person listed as executive officer and director, over about 5 years. Across those companies the filings report $225.1M sold in total.

Listed alongside Armen Shanafelt (4 shared filings), Grant E Pickering (4 shared filings), Jeff Fairman (4 shared filings), Kurt von Emster (4 shared filings), Patrick Enright (4 shared filings) and 26 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.

1 of the issuers belongs to the sponsor group Symic (2 issuers, $30.8M reported sold, 2013–2017).

What this means A sponsor group is one team that sets up a new company for each deal. Symic has 2 companies on file and $30.8M 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, 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) — 26 bankruptcy cases matching the name listed in Key records below.

What this means 26 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 11 public filings for William Newell and found 8 differences, 1 worth asking the sponsor about: 4 Form Ds were filed more than 15 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.

What this means A bankruptcy filing was found. Many are old or personal and have nothing to do with the deal — but ask what it was and when it closed.

5 offerings have no amendment in the last 12 months and may still be open

No amendment in the last 12 months on an offering that may still be open — SUTRO BIOPHARMA INC (latest filing Aug 8, 2018) · No amendment in the last 12 months on an offering that may still be open — SutroVax, Inc.

(latest filing Jul 24, 2015)

What this means SEC rules expect a yearly amendment while an offering is still going. Ask the sponsor which of these raises have closed.

Sources
Note · Jun 6, 2018 – Aug 8, 2018

Offering amount changed between filings — SUTRO BIOPHARMA INC

The Jun 6, 2018 filing says $60,000,000 offered; the Aug 8, 2018 Form D/A says $85,382,351.

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.

Sources
Note · Jul 24, 2015 – Dec 7, 2015

William Newell is written 2 different ways on the filings

listed as "William Newell" on 7 filings (from Jul 24, 2015), and "William J. Newell" on 4 filings (from Dec 7, 2015).

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.

Note · Dec 7, 2015 – May 26, 2017

Address moved from San Francisco, CA to Emeryville, CA — Symic Holdings, LLC

The people listed on the Dec 7, 2015 filing give San Francisco, CA; on the May 26, 2017 filing they give Emeryville, CA. The address now on file (5980 Horton Street, Suite 600, Emeryville, CA) is a registered-agent or shared-office address used by 6 issuers.

What this means A registered agent's address is a mailbox, not where the team works. Ask where the business actually operates.

Sources
Note · Jul 24, 2015 – Mar 21, 2017

Address moved from South San Francisco, CA to Foster City, CA — SutroVax, Inc.

The people listed on the Jul 24, 2015 filing give South San Francisco, CA; on the Mar 21, 2017 filing they give Foster City, CA.

What this means Businesses move; this just shows the two places and dates. If you were told one city and the forms say another, ask which is current.

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.

"Paid to sell it" = sales compensation recipients named on that filing (Item 12), each linked to FINRA BrokerCheck when a CRD number is reported.
