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.

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), state securities regulators (AZ, CA, DE, TX, WA) — 3 bankruptcy cases matching the name listed in Key records below. Not yet searched: SEC enforcement releases (search queued; results are added automatically).

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.

Key records

Five things investors ask first. Items still in human review are counted, not shown.

1. Lawsuits

None found in sources searched

What was searched

Sources searched: CourtListener bulk data (RECAP dockets as of 2026-09-30; recall-first rule 10-24) — federal district + bankruptcy courts; live RECAP re-check pending. State courts: not yet searched. PACER: not searched. · Last checked Oct 24, 2026, 2:16 AM ET.

Washington (dw.courts.wa.gov; bulk index reports under a JISC data-dissemination agreement), Delaware (CourtConnect; Court of Chancery not included) and Arizona (apps.azcourts.gov/publicaccess, which has an official channel to request high-volume access) are the candidates; PartnerFacts will request written permission before any automated search.

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).
