The short version

Jonathan T. Silverstein is listed as an executive officer, director, and promoter on 104 SEC Form D filings by 33 issuers between Mar 2009 and Jul 2024. Largest by amount reported sold: OrbiMed Partners II, L.P. (New York, NY — pooled investment fund — 2011–2021; $1.78B reported sold to 880 investors), OrbiMed Royalty Opportunities II, LP (New York, NY — pooled investment fund — 2015; $900M reported sold to 83 investors), OrbiMed Royalty & Credit Opportunities III, LP (New York, NY — pooled investment fund — 2019; $889.8M reported sold to 69 investors), OrbiMed Private Investments V, LP (New York, NY — pooled investment fund — 2013; $699.5M reported sold to 66 investors), OrbiMed Asia Partners III, L.P. (New York, NY — pooled investment fund — 2017; $540M reported sold to 97 investors) and 28 more (all listed below).

What this means That is a lot of deals — 33 separate companies raised money with this person listed as executive officer, director, and promoter, over about 15 years. Across those companies the filings report $7.27B sold in total.

Listed alongside Carl L. Gordon (63 shared filings), W. Carter Neild (58 shared filings), Sven H. Borho (55 shared filings), OrbiMed Advisors LLC (50 shared filings, management entity), Geoffrey C. Hsu (49 shared filings) and 166 others.

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

The issuers belong to 3 sponsor groups: Orbimed (37 issuers, $20.2B reported sold, 2009–2026), Rhythm Pharmaceuticals (3 issuers, $54M reported sold, 2010–2017) and Group linked by Olav B. Bergheim (14 issuers, $144.9M reported sold, 2008–2025).

What this means This person is listed across more than one sponsor team; each group page shows that team's full track record.

Public records searched: federal courts (CourtListener / RECAP), SEC enforcement releases, state securities regulators (AZ, CA, DE, TX, WA) — 2 bankruptcy cases matching the name listed in Key records below.

What this means 2 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 the newest 50 of 104 public filings for Jonathan T. Silverstein and found 19 differences, 4 worth asking the sponsor about: 4 Form Ds were filed more than 15 days after the first sale; Jonathan T. Silverstein is no longer listed on the Dec 9, 2022 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.

NY on 56 filings (Mar 11, 2011 to Dec 10, 2021); CA on 5 filings (Jan 27, 2016 to Oct 22, 2019); CO on 1 filing (Sep 26, 2016); NJ on 1 filing (Sep 30, 2016); MA on 3 filings (Jan 6, 2017 to May 11, 2018); IL on 2 filings (Sep 15, 2021 to Jul 5, 2024).

What this means The address on a Form D is usually the company's, not the person's home, so this often just reflects different companies. It can also mean a move. Nothing wrong by itself.

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. We compared the newest 50 of 104 filings (work cap); older filings are not covered here. As of Oct 24, 2026.

How this is counted

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.

Counted across every filing this person is listed on (latest filing per offering, per issuer).

Deals 33

Every issuer that named Jonathan T. Silverstein on a Form D, newest first. A Form D is the notice a company files after it starts selling a private investment.
