What this means Nothing turned up where we looked (3 sources). That does not prove there is nothing — it means none was found in those sources on that date.
We compared the newest 50 of 91 public filings for Jonathan A. Seiffer and found 12 differences, 3 worth asking the sponsor about: Investor count went down between filings; 5 Form Ds were filed more than 15 days after the first sale; 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.

12 differences found between the filings for Jonathan A. Seiffer — 3 worth asking about (compared the newest 50 of 91 filings on Oct 24, 2026; older filings not covered)
United States Bankruptcy Court, E.D. California docket "George Leonard Green" filed Jan 23, 2004, closed May 23, 2006. C. Leonard Green & Partners, L.P. (listed on the same filings) is listed as Party ("George Leonard Green"). Our match estimate: 60%.
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.
United States Bankruptcy Court, S.D. California docket "Leonard Green and Kathleen Malvern Green" filed Nov 18, 2003, closed Feb 23, 2004. C. Leonard Green & Partners, L.P. (listed on the same filings) is listed as Party ("Leonard Green and Kathleen Malvern Green"). Our match estimate: 60%.
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.
United States Bankruptcy Court, S.D. California docket "Leonard Green and Donna Sigrid Green" filed Feb 10, 1992, closed Jul 15, 1992. C. Leonard Green & Partners, L.P. (listed on the same filings) is listed as Party ("Leonard Green and Donna Sigrid Green"). Our match estimate: 60%.

The Sep 22, 2022 filing reports 35 investors; the Sep 22, 2023 Form D/A reports 34 investors.
What this means Investor counts normally only grow. A smaller number can mean investors left or were refunded, or a count was corrected. Ask the sponsor what happened.
Form D filed 175 days after the first sale — Sun TopCo, LP · Form D filed 35 days after the first sale — EXW Coinvest LP · Form D filed 57 days after the first sale — Beacon Holding Inc. · Form D filed 17 days after the first sale — LGP Associates VI-A LLC · Form D filed 17 days after the first sale — LGP Associates VI-B LLC
What this means Late notices are common and carry no penalty by themselves. A pattern of late paperwork is worth asking the sponsor about.
No amendment in the last 12 months on an offering that may still be open — Sun TopCo, LP (latest filing Oct 4, 2024) · No amendment in the last 12 months on an offering that may still be open — Shingle Acquisition Holdings, Inc. (latest filing Apr 12, 2024) · No amendment in the last 12 months on an offering that may still be open — Sun TopCo, LP (latest filing Sep 22, 2022) · No amendment in the last 12 months on an offering that may still be open — Sun TopCo, LP (latest filing Jun 24, 2022) · No amendment in the last 12 months on an offering that may still be open — Beacon Holding Inc. (latest filing Apr 10, 2017) · and 1 more

Jonathan A. Seiffer appears on the Jun 7, 2018 Form D (executive officer) but not on the Jul 11, 2018 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 Jan 30, 2017 filing says $9,635,000 offered; the Feb 10, 2017 Form D/A says $9,655,000.
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.
listed as "Jonathan A. Seiffer" on 33 filings (from Jul 14, 2014), and "Jonathan Seiffer" on 17 filings (from Jun 7, 2018).
What this means Same person, written differently — a middle name or suffix left off, or spelled another way. It is normal, but check that the full legal name matches your subscription documents.
"Pooled Investment Fund" (Jun 7, 2018 to Jul 11, 2018); then "Other" (Jul 30, 2018).
What this means The issuer described its business differently on different forms. Often it is just a different box ticked; sometimes the deal itself changed. Ask which business your money is in.
This page covers filings where the address state is CA. A separate record, "Jonathan Seiffer" with address state TX, is listed on 3 filings — most recently by CALIBER HOLDINGS INC. (Jun 25, 2026). The two records do not overlap in time: this page runs Mar 21, 2011 to Apr 10, 2017; the other runs Feb 22, 2024 to Jun 25, 2026.
What this means Could be the same person who moved, or two people with the same name. We keep them apart until a filing ties them together. Check both pages before you decide.
The people listed on the Jun 7, 2018 filing give Los Angeles, CA; on the Jul 11, 2018 filing they give Mckinney, TX.
What this means Businesses move; this just shows the two places and dates. If you were told one city and the forms say another, ask which is current.
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. We compared the newest 50 of 91 filings (work cap); older filings are not covered here. As of Oct 24, 2026.

Counts come from Form D Items 12–15 on the filings in our index (latest filing per offering; one offering = one SEC file number; an amendment updates its offering rather than adding one).

A shared address can mean the same team, a shared office building or a registered agent. It is a lead, not a conclusion.
Individuals are not matched to business registrations — registries list companies, and a name alone is not enough to tie a person to one. 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. Secretary of State file data (data.texas.gov), data as of Oct 24, 2026). Registries of other states have not been searched: many publish no bulk file and require a CAPTCHA or bot challenge on their search page, which we do not bypass (Delaware, for example, offers no public bulk file).
None of the 29 issuers this person is listed on appears in Form ADV (searched 24,962 advisers as of Oct 2, 2026). A person is never an adviser firm; Form ADV is checked for the issuers and the management companies they are listed with.
Searched SEC Regulation A Data Sets (Forms 1-A, 1-K, 1-Z; 2015 Q2 → 2026 Q3); SEC Crowdfunding Offerings Data Sets (Form C family; 2016 Q2 → 2026 Q3); EDGAR form index for 2026 Q3 → 2026 Q4 (51,358 records as of Oct 23, 2026, 8:41 PM ET) — nothing matched this name.
Property records are matched to companies only, never to individuals, so none are matched to Jonathan A. Seiffer by design. Searched property records in Hillsborough County FL (Clerk recorded-document index Oct 14, 2026 to Oct 15, 2026 + FL DOR 2026 ownership roll), Miami-Dade County FL (FL DOR 2026 ownership roll), Harris County TX (HCAD 2026 ownership roll), Dallas County TX (DCAD 2026 ownership roll), New York City ACRIS documents and PLUTO ownership rows already retrieved for other issuers, Cook County IL sale and ownership rows already retrieved for other issuers (814,874 records as of Oct 23, 2026, 8:59 PM ET) for the 29 issuers this person is listed on — nothing matched.
