United States Bankruptcy Court, D. Massachusetts docket "Aquino v. Berstein-Magoon-Gay, LLC" filed Jun 3, 2025 (Open). Sumner Berstein is listed as Defendant ("Berstein-Magoon-Gay, LLC"). Our match estimate: 51%.
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 Apr 10, 2012 Form D reports $662,000 sold and $210,000 of the proceeds used for payments to officers, directors or promoters.
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.
JB Therapeutics, Inc. (last filing Apr 10, 2012; $662,000 sold of $1,500,000). 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 latest filing for this offering is dated Apr 10, 2012 (first sale Apr 5, 2012). It reports $662,000 sold of $1,500,000 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.
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.
0 of 1 offering report sales commissions; 0 report finder's fees; 1 reports proceeds to related persons totalling $210,000.
