What this means 19 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.

Comparisons cover issuers and sponsor groups — see the issuer pages under Deals
15 differences found between the filings for Michael Weiss — 2 worth asking about (compared 14 filings on Oct 24, 2026)
United States Bankruptcy Court, E.D. New York docket "Gerald L Greenwald" filed Feb 5, 1999, closed Jun 14, 1999. Gerald Greenwald (listed on the same filings) is listed as Debtor ("Gerald L Greenwald"). Our match estimate: 70%.
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.
The Feb 22, 2012 Form D/A reports $20,875,405 sold and $2,412,736 of the proceeds used for payments to officers, directors or promoters (marked as an estimate).
What this means The filing reports how much of the money raised was paid to insiders. Over 10% is high for most deals. Ask what it paid for.
Castle Peak Fund I LLC (last filing Oct 17, 2024; $22,618,498 sold of $49,000,000); AVENUE THERAPEUTICS, INC. (last filing Feb 14, 2023; $242,537 sold of $5,000,000). Each has no filing in more than two years and reported under half its target sold.
What this means An issuer whose last filing is more than two years old and reported under half its target sold. The raise may have closed early or quietly stopped. Ask what happened to each.
The filing says the first sale was Dec 30, 2011. The Form D was filed Mar 26, 2012 — 87 days later. The rule: a Form D is generally due within 15 days after the first sale, so this one is 72 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.
The filing says the first sale was Sep 3, 2021. The Form D was filed Sep 20, 2021 — 17 days later. The rule: a Form D is generally due within 15 days after the first sale, so this one is 2 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.
No amendment in the last 12 months on an offering that may still be open — Castle Peak Fund I LLC (latest filing Dec 17, 2019) · No amendment in the last 12 months on an offering that may still be open — Fortress Biotech, Inc. (latest filing Mar 13, 2018) · No amendment in the last 12 months on an offering that may still be open — AVENUE THERAPEUTICS, INC. (latest filing Jan 12, 2017) · No amendment in the last 12 months on an offering that may still be open — Enumeral Biomedical Corp. (latest filing May 7, 2014) · No amendment in the last 12 months on an offering that may still be open — Enumeral Biomedical Corp. (latest filing Feb 10, 2014) · and 1 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.
Michael Weiss appears on the Jun 9, 2021 Form D/A (executive officer) but not on the May 16, 2022 Form D/A for the same offering.
What this means People leave, and the issuer must list only current officers, directors and promoters. It is still worth asking why this person left and who replaced them.
The Mar 16, 2010 filing says $4,000,000 offered; the Feb 22, 2012 Form D/A says $25,000,000.
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.
The Mar 16, 2010 filing lists a minimum of $5,000; the Feb 22, 2012 Form D/A lists $50,000.
What this means A different minimum usually means the offering terms changed. Check which terms apply to you.

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.

Officers and managers appear by name inside each matched company's record on the issuer pages. Registries searched: AL (Alabama Secretary of State — Business Entity Records (arc-sos.state.al.us), searched by issuer name, data as of Oct 24, 2026); CO (Colorado Secretary of State — Business Entities in Colorado (data.colorado.gov), data as of Oct 23, 2026); CT (Connecticut Secretary of the State — Business Registry (data.ct.gov), data as of Oct 24, 2026); FL (Florida Department of State, Division of Corporations — quarterly corporate data file (Sunbiz), data as of Oct 7, 2026); NY (New York Department of State — Corporations and Other Entities (data.ny.gov: All Filings + Active Corporations), data as of Oct 20, 2026); OR (Oregon Secretary of State — Active Businesses, All (data.oregon.gov), data as of Oct 20, 2026); PA (Pennsylvania Department of State — Registered Businesses, Current (data.pa.gov), data as of Oct 6, 2026); TX (Texas Comptroller — Active Franchise Taxpayers incl.
