The short version

David Walt is listed as an executive officer and director on 24 SEC Form D filings by 8 issuers between Oct 2010 and Sep 2026. Largest by amount reported sold: Arbor Biotechnologies, Inc. (Cambridge, MA — biotechnology — 2017–2021; $215M reported sold to 37 investors), Vizgen, Inc. (Waltham, MA — biotechnology — 2021–2026; $107.6M reported sold to 61 investors), Sherlock Biosciences, Inc. (Brighton, MA — other health care — 2019–2022; $80M reported sold to 13 investors), Quanterix Corp (Billerica, MA — other technology — 2010–2019; $45.6M reported sold to 15 investors), Ultivue, Inc. (Cambridge, MA — biotechnology — 2015–2019; $26.5M reported sold to 14 investors) and 3 more (all listed below).

What this means A repeat sponsor — 8 separate companies raised money with this person listed as executive officer and director, over about 16 years. Across those companies the filings report $501.7M sold in total.

Listed alongside Keith Crandell (18 shared filings), Douglas Cole (7 shared filings), Paul Meister (7 shared filings), Martin Madaus (6 shared filings), Andrea Jackson (5 shared filings) and 61 others.

What this means These are the other officers, directors or promoters the companies named on the same forms — the team around David. Each name links to their own page.

2 of the issuers belong to the sponsor group Arbor (2 issuers, $217M reported sold, 2017–2026).

What this means A sponsor group is one team that sets up a new company for each deal. Arbor has 2 companies on file and $217M 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 (AZ, CA, DE, TX, WA) — 2 bankruptcy cases 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 24 public filings for David Walt and found 9 differences, 1 worth asking the sponsor about: Form D filed 588 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

Comparisons cover issuers and sponsor groups — see the issuer pages under Deals

9 differences found between the filings for David Walt — 1 worth asking about (compared 24 filings on Oct 24, 2026)

Worth asking · Feb 14, 2025 – Sep 25, 2026

Form D filed 588 days after the first sale — Way Biosolutions, Inc.

The filing says the first sale was Feb 14, 2025. The Form D was filed Sep 25, 2026 — 588 days later. The rule: a Form D is generally due within 15 days after the first sale, so this one is 573 days past that.

What this means The notice went in months after money was taken in. Late notices are common and carry no penalty by themselves, but it is fair to ask the sponsor why the paperwork lagged.

Note · Aug 21, 2015 – Jul 21, 2017

David Walt's role changed at Ultivue, Inc.: executive officer, director → director

The Aug 21, 2015 filing lists David Walt as executive officer, director; the Jul 21, 2017 Form D lists director.

What this means Roles on Form D are self-reported by the issuer. A change can mean a real change in who runs the company, or just a different box ticked. Ask who makes decisions today.

Offering amount changed between filings — Ultivue, Inc.

The Jul 21, 2017 filing says $13,999,997 offered; the Feb 1, 2018 Form D/A says $20,499,996.

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.

10 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 — Vizgen, Inc. (latest filing Oct 7, 2025) · No amendment in the last 12 months on an offering that may still be open — Vizgen, Inc. (latest filing Oct 22, 2024) · No amendment in the last 12 months on an offering that may still be open — Vizgen, Inc. (latest filing May 5, 2022) · No amendment in the last 12 months on an offering that may still be open — Quanterix Corp (latest filing Jul 11, 2019) · No amendment in the last 12 months on an offering that may still be open — Sherlock Biosciences, Inc. (latest filing Apr 25, 2019) · and 5 more

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

David Walt is written 2 different ways on the filings

listed as "David Walt" on 16 filings (from Oct 12, 2010), and "David R. Walt" on 8 filings (from Aug 21, 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.

What this means The issuer described its business differently on different forms. Often it is just a different box ticked; sometimes the deal itself changed. Ask which business your money is in.

Same name, different state: "David Walt" (CA) is a separate record

This page covers filings where the address state is MA. A separate record, "David Walt" with address state CA, is listed on 1 filing — most recently by Protillion Biosciences, lnc. (Dec 21, 2022). Both records have filings in the same period (Dec 21, 2022).

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.

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).

Deals 8

Every issuer that named David Walt on a Form D, newest first. A Form D is the notice a company files after it starts selling a private investment.

None of the 8 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.

Other offering types (Regulation A and Regulation Crowdfunding)

Property records none — individuals are not matched

Property records are matched to companies only, never to individuals, so none are matched to David Walt by design.
