What this means 14 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 10 public filings for Michael Sweeney and found 9 differences: Bankruptcy case: Sears, Roebuck And Co. v. Rezai; 5 offerings have no amendment in the last 12 months and 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.

Sweeney (Registered Principal, Philadelphia, Pennsylvania) submitted a Letter of Acceptance, Waiver and Consent pursuant to which they were censured and fined $12,000, jointly and severally.

9 differences found between the filings for Michael Sweeney (compared 10 filings on Oct 24, 2026)

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.
No amendment in the last 12 months on an offering that may still be open — NANOSTIM INC (latest filing May 3, 2013) · No amendment in the last 12 months on an offering that may still be open — NANOSTIM INC (latest filing Oct 18, 2012) · No amendment in the last 12 months on an offering that may still be open — NANOSTIM INC (latest filing May 23, 2012) · No amendment in the last 12 months on an offering that may still be open — NANOSTIM INC (latest filing Apr 13, 2011) · No amendment in the last 12 months on an offering that may still be open — CALYPSO MEDICAL TECHNOLOGIES INC (latest filing Sep 28, 2009)

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.

Individuals are not matched to business registrations — registries list companies, and a name alone is not enough to tie a person to one.
