The short version

Martin J Kossoff is listed as a director on 1 SEC Form D filing by 1 issuer in Mar 2026: AMBER SEMICONDUCTOR, INC. (Dublin, CA — industry reported as "Other" — 2026; $9.35M reported sold to 50 investors).

What this means One deal on file with the SEC, filed Mar 2026. 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 THAR CASEY (1 shared filing).

What this means These are the other officers, directors or promoters the companies named on the same forms — the team around Martin. 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) — 12 court cases matching the name, 5 bankruptcy cases matching the name listed in Key records below.

What this means 17 records came back, including 3 court cases 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 1 public filing for Martin J Kossoff and found 1 difference: Form D filed 21 days after the first sale.

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

1 difference found between the filings for Martin J Kossoff (compared 1 filing on Oct 24, 2026)

Note · Feb 26, 2026 – Mar 19, 2026

Form D filed 21 days after the first sale — AMBER SEMICONDUCTOR, INC.

The filing says the first sale was Feb 26, 2026. The Form D was filed Mar 19, 2026 — 21 days later. The rule: a Form D is generally due within 15 days after the first sale, so this one is 6 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.

Sources
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.
