The short version

Ronald Baron is listed as an executive officer and director on 2 SEC Form D filings by 1 issuer in Mar 2009: Castle Advisers, L.P. (New York, NY — pooled investment fund — 2009; $184.4M reported sold to 177 investors).

What this means One deal on file with the SEC, filed Mar 2009. A Form D is the notice a company files after it starts selling a private investment — it is a notice, not an approval.

Listed alongside Anita Nagler (2 shared filings), Chris Dodds (2 shared filings), Cliff Greenberg (2 shared filings), Linda Martinson (2 shared filings), Management, Inc. Baron Capital (2 shared filings) and 3 others.

What this means These are the other officers, directors or promoters the companies named on the same forms — the team around Ronald. Each name links to their own page.

The issuer belongs to the sponsor group Baronx (8 issuers, $1.91B reported sold, 2009–2026).

What this means A sponsor group is one team that sets up a new company for each deal. Baronx has 8 companies on file and $1.91B reported sold in total — the group page shows the whole track record in one place.

Public records searched: federal courts (CourtListener / RECAP), SEC enforcement releases, state securities regulators (AZ, CA, DE, TX, WA) — 1 SEC release, 10 bankruptcy cases matching the name listed in Key records below.

What this means 11 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 2 public filings for Ronald Baron and found 3 differences, 1 worth asking the sponsor about: Ronald Baron is no longer listed on the Jul 29, 2026 amendment; 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.

4. Differences between public sources

Comparisons cover issuers and sponsor groups — see the issuer pages under Deals

3 differences found between the filings for Ronald Baron — 1 worth asking about (compared 2 filings on Oct 24, 2026)

Worth asking · Mar 24, 2009 – Jul 29, 2026

Ronald Baron is no longer listed on the Jul 29, 2026 amendment — Castle Advisers, L.P.

Ronald Baron appears on the Mar 24, 2009 Form D/A (executive officer, director) but not on the Jul 29, 2026 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.

Sources
Note · Mar 11, 2009 – Jul 29, 2026

Reported net asset value range changed between filings — Castle Advisers, L.P.

"Not Applicable" (Mar 11, 2009); then "Decline to Disclose" (Jul 29, 2026).

What this means This is the size band the issuer picks for itself on the form. A change can mean the business grew or shrank — or that it chose not to say. Ask for current numbers.

Sources
Note · Mar 24, 2009 – Jul 29, 2026

Minimum investment changed between filings — Castle Advisers, L.P.

The Mar 24, 2009 filing lists a minimum of $500,000; the Jul 29, 2026 Form D/A lists $25,000.

What this means A different minimum usually means the offering terms changed. Check which terms apply to you.

Sources
What is compared

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.

5. Money to insiders

None reported on 1 offering — no sales commissions, finder's fees or proceeds to insiders

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). "To insiders" = gross proceeds used for payments to executive officers, directors or promoters. "—" = not reported on that filing. Amounts marked (est.) were reported as estimates. "Paid to sell it" = sales compensation recipients named on that filing (Item 12), each linked to FINRA BrokerCheck when a CRD number is reported.
