The short version

Michael Kleinberg is listed as an executive officer and director on 3 SEC Form D filings by 2 issuers between Jun 2021 and Oct 2026: FORGE NANO, INC. (Thornton, CO — other technology — 2021; $44.2M reported sold to 33 investors) and Advanced Thermovoltaic Systems, Corp. (Loveland, CO — other energy — 2026; $9M reported sold to 1 investors).

What this means 2 separate companies raised money with this person listed as executive officer and director, over about 5 years. Across those companies the filings report $53.2M sold in total.

Listed alongside Douglas Hudson (2 shared filings), Edward Ganja (2 shared filings), Jonathan Candee (2 shared filings), Kelly Adams (2 shared filings), Terrel Hill (2 shared filings) and 9 others.

What this means These are the other officers, directors or promoters the companies named on the same forms — the team around Michael. 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) — 15 court cases matching the name, 4 bankruptcy cases matching the name listed in Key records below.

What this means 19 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 3 public filings for Michael Kleinberg and found 3 differences: Form D filed 18 days after the first sale; No amendment in the last 12 months on an offering that may still be open; 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

3 differences found between the filings for Michael Kleinberg (compared 3 filings on Oct 24, 2026)

Note · Jul 13, 2026 – Jul 31, 2026

Form D filed 18 days after the first sale — Advanced Thermovoltaic Systems, Corp.

The filing says the first sale was Jul 13, 2026. The Form D was filed Jul 31, 2026 — 18 days later. The rule: a Form D is generally due within 15 days after the first sale, so this one is 3 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
Note · Jun 3, 2021 – Jun 21, 2021

Form D filed 18 days after the first sale — FORGE NANO, INC.

The filing says the first sale was Jun 3, 2021. The Form D was filed Jun 21, 2021 — 18 days later. The rule: a Form D is generally due within 15 days after the first sale, so this one is 3 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
Note · Jun 3, 2021 – Jun 21, 2021

No amendment in the last 12 months on an offering that may still be open — FORGE NANO, INC. (latest filing Jun 21, 2021)

The latest filing for this offering is dated Jun 21, 2021 (first sale Jun 3, 2021). It reports $2,815,757 sold of $9,999,958 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.

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.

5. Money to insiders

None reported on 2 offerings — no sales commissions, finder's fees or proceeds to insiders
