The short version

Jonathan Root is listed as a director on 67 SEC Form D filings by 19 issuers between May 2009 and Apr 2026. Largest by amount reported sold: Edgewise Therapeutics, Inc. (Boulder, CO — biotechnology — 2019–2020; $95M reported sold to 21 investors), Silverback Therapeutics, Inc. (Seattle, WA — biotechnology — 2020; $85M reported sold to 31 investors), CARLSMED, INC. (Carlsbad, CA — industry reported as "Other" — 2022–2025; $64.5M reported sold to 50 investors), Sparrow Pharmaceuticals, Inc. (Portland, OR — pharmaceuticals — 2024–2025; $61.8M reported sold to 17 investors), EFFECTOR THERAPEUTICS, INC. (San Diego, CA — biotechnology — 2014–2016; $56M reported sold to 26 investors) and 14 more (all listed below).

What this means That is a lot of deals — 19 separate companies raised money with this person listed as director, over about 17 years. Across those companies the filings report $685.4M sold in total.

Listed alongside Donald Milder (18 shared filings), Jack Lasersohn (18 shared filings), Robert Rosenbluth (18 shared filings), Brian Cox (16 shared filings), Paul Lubock (12 shared filings) and 132 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.

Public records searched: federal courts (CourtListener / RECAP), SEC enforcement releases, state securities regulators (AZ, CA, DE, TX, WA) — 3 bankruptcy cases matching the name listed in Key records below.

What this means 3 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 67 public filings for Jonathan Root and found 10 differences, 1 worth asking the sponsor about: 6 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.

4. Differences between public sources

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

10 differences found between the filings for Jonathan Root — 1 worth asking about (compared the newest 50 of 67 filings on Oct 24, 2026; older filings not covered)

Worth asking · Dec 14, 2015 – Apr 20, 2026

6 Form Ds were filed more than 15 days after the first sale

Form D filed 97 days after the first sale — Route 92 Medical, Inc. · Form D filed 62 days after the first sale — Cleave Biosciences, Inc. · Form D filed 16 days after the first sale — AIS VGP-6, LLC · Form D filed 16 days after the first sale — NUVAIRA, INC. · Form D filed 30 days after the first sale — Edgewise Therapeutics, Inc. · and 1 more

Same name, different state: "Jonathan D Root" (CA or NY) is a separate record

This page covers filings where the address state is CA or MN or MA or CO or WA or OR or UT. A separate record, "Jonathan D Root" with address state CA or NY, is listed on 16 filings — most recently by U.S. Venture Partners XIV, L.P. (Jul 31, 2026). Both records have filings in the same period (Sep 19, 2014 to Jan 29, 2026).

What this means Two records with one name were active at the same time. That can be one person listing different company addresses, or two different people. We keep them apart until a filing ties them together. Check both pages before you decide.

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 67 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). "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 19

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

Registrations and other filings

Adviser registration (Form ADV)

None of the 19 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.

Other offering types (Regulation A and Regulation Crowdfunding)

Property records none — individuals are not matched

Property records are matched to companies only, never to individuals, so none are matched to Jonathan Root by design.
