The short version

David Feinberg is listed as an executive officer on 5 SEC Form D filings by 3 issuers between Mar 2022 and Sep 2025: Nurture Genomics, Inc. (Cambridge, MA — other health care — 2022–2025; $4.33M reported sold to 40 investors), Adaptive Surface Technologies, Inc. (Cambridge, MA — other technology — 2022; $3.82M reported sold to 4 investors) and College Guidance Network, Inc. (Lexington, MA — industry reported as "Other" — 2023; $1.16M reported sold to 13 investors).

What this means A repeat sponsor — 3 separate companies raised money with this person listed as executive officer, over about 3 years. Across those companies the filings report $9.32M sold in total.

Listed alongside Robert C Green (3 shared filings), Hans Keil (2 shared filings), Andrew Stevenson (1 shared filing), Curtis Maas (1 shared filing), David Ward (1 shared filing) and 8 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.

Public records searched: federal courts (CourtListener / RECAP), SEC enforcement releases, state securities regulators (AZ, CA, DE, TX, WA) — 2 court cases matching the name, 14 bankruptcy cases matching the name listed in Key records below.

What this means 16 records came back, including 1 court case still open — open cases can take years and cost money. 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 5 public filings for David Feinberg and found 10 differences: Form D filed 27 days after the first sale; Offering amount changed between filings; 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

10 differences found between the filings for David Feinberg (compared 5 filings on Oct 24, 2026)

Note · Feb 22, 2022 – Mar 21, 2022

Form D filed 27 days after the first sale — Adaptive Surface Technologies, Inc.

The filing says the first sale was Feb 22, 2022. The Form D was filed Mar 21, 2022 — 27 days later. The rule: a Form D is generally due within 15 days after the first sale, so this one is 12 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.

Note · Aug 8, 2023 – Sep 9, 2025

The Aug 8, 2023 filing says $5,000,000 offered; the Sep 9, 2025 Form D/A says $6,000,000.

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.

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).
