10 differences found between the filings for Johnathan Seeg — 1 worth asking about (compared 10 filings on Oct 24, 2026)
United States Bankruptcy Court, D. New Jersey docket "Chase Bank USA, N.A. v. Baranski" filed Sep 9, 2005, closed Jan 20, 2006. Lynn Baranski (listed on the same filings) is listed as Defendant ("Baranski"). 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 filing says the first sale was Feb 7, 2022. The Form D was filed Feb 28, 2022 — 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.
The filing says the first sale was Mar 26, 2021. The Form D was filed Apr 12, 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.
The latest filing for this offering is dated Jul 1, 2024 (first sale Mar 15, 2022). It reports $323,834,661 sold of an indefinite amount 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.
The latest filing for this offering is dated Apr 12, 2022 (first sale Mar 26, 2021). It reports $331,585,514 sold of an indefinite amount 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.
Johnathan Seeg appears on the Mar 4, 2024 Form D/A (executive officer) but not on the Mar 7, 2024 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 30, 2022 filing lists Johnathan Seeg as executive officer; the Jul 1, 2024 Form D/A lists director.
What this means Roles on Form D are self-reported by the issuer. A change can mean a real change in who runs the company, or just a different box ticked. Ask who makes decisions today.
The people listed on the Mar 11, 2024 filing give New York, NY; on the Jul 1, 2024 filing they give Princeton, NJ. The address now on file (1 University Square Drive, 5th Floor, Princeton, NJ) is a registered-agent or shared-office address used by 34 issuers.
What this means A registered agent's address is a mailbox, not where the team works. Ask where the business actually operates.

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.
