The short version

John Springer is listed as an executive officer and director on 4 SEC Form D filings by 2 issuers between Apr 2020 and Sep 2024: R3 Vascular Inc. (Mountain View, CA — other health care — 2020–2024; $72.5M reported sold to 34 investors) and Nectero Medical Inc (Tempe, AZ — biotechnology — 2020–2021; $32.8M reported sold to 31 investors).

What this means 2 separate companies raised money with this person listed as executive officer and director, over about 4 years. Across those companies the filings report $105.3M sold in total.

Listed alongside Kamal Ramzipoor (2 shared filings), Amir Abolfathi (1 shared filing), Bruce Roberts (1 shared filing), Christopher M. Owens (1 shared filing), David Neustaedter (1 shared filing) and 5 others.

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

1 of the issuers belongs to the sponsor group Nectero (2 issuers, $33.5M reported sold, 2020–2024).

What this means A sponsor group is one team that sets up a new company for each deal. Nectero has 2 companies on file and $33.5M 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 (AK, AL, AR, AZ, CA, CO, CT, DC, DE, FINRA, FL, GA, HI, ID, IL, KS, KY, LA, MA, MD, ME, MI, MO, MS, MT, NASAA, NC, ND, NH, NM, NV, NY, OH, OK, OR, PA, RI, SC, SD, TN, TX, UT, VT, WA, WI, WV, WY) — 1 court case matching the name, 47 bankruptcy cases matching the name listed in Key records below.

What this means 48 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 4 public filings for John Springer and found 14 differences, 2 worth asking the sponsor about: Form D filed 139 days after the first sale; Form D filed 278 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.

Court records show docket facts only; we never restate allegations as facts. Outcome wording comes from the docket feed; where it does not state a disposition we say so.

State courts: not covered (one-tap state court links under Look further). No state offers a lawful automated statewide source PartnerFacts can use today. Texas (re:SearchTX) terms prohibit storing results in a database open to third parties; New York (WebCivil) and Massachusetts (MassCourts) require a browser check that blocks scripted queries; California has no statewide index (58 county portals; Rule of Court 2.503 grants name-based access case by case); Florida, Utah and Illinois offer paid or partial access whose terms for automated use are unverified. 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.

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

14 differences found between the filings for John Springer — 2 worth asking about (compared 4 filings on Oct 24, 2026)

Note · Mar 28, 1997 – Aug 19, 1997

Bankruptcy case: AFBA Industrial Bank v. Neustaedter — filed Mar 28, 1997

United States Bankruptcy Court, S.D. California docket "AFBA Industrial Bank v. Neustaedter" filed Mar 28, 1997, closed Aug 19, 1997. David Neustaedter (listed on the same filings) is listed as Defendant ("Neustaedter"). Our match estimate: 70%.

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.

17% of the money raised went to insiders — R3 Vascular Inc.

The May 18, 2020 Form D reports $2,667,917 sold and $450,000 of the proceeds used for payments to officers, directors or promoters (marked as an estimate). Issuer's note: "Estimated payments to officers for 12 months in fulfillment of executive and BOD services.".

What this means The filing reports how much of the money raised was paid to insiders. Over 10% is high for most deals. Ask what it paid for.

Form D filed 139 days after the first sale — R3 Vascular Inc.

The filing says the first sale was Apr 26, 2024. The Form D was filed Sep 12, 2024 — 139 days later. The rule: a Form D is generally due within 15 days after the first sale, so this one is 124 days past that.

What this means A late notice is common and carries no penalty by itself. It is worth asking the sponsor why the paperwork lagged.

Form D filed 278 days after the first sale — R3 Vascular Inc.

What this means The notice went in months after money was taken in. Late notices are common and carry no penalty by themselves, but it is fair to ask the sponsor why the paperwork lagged.

No amendment in the last 12 months on an offering that may still be open — R3 Vascular Inc. (latest filing Sep 12, 2024)

The latest filing for this offering is dated Sep 12, 2024 (first sale Apr 26, 2024). It reports $72,499,781 sold of an indefinite amount offered. No later amendment is in our index as of Oct 24, 2026.

What this means SEC rules expect a yearly amendment while an offering is still going. The raise may simply have ended — a Form D does not say when it closed. Ask the sponsor whether the offering closed, when, and at what amount.

John Springer's role changed at R3 Vascular Inc.: executive officer, director → director

The May 18, 2020 filing lists John Springer as executive officer, director; the Sep 12, 2024 Form D lists director.

What this means Roles on Form D are self-reported by the issuer. A change can mean a real change in who runs the company, or just a different box ticked. Ask who makes decisions today.

John Springer is listed with 2 different address states: PA, CA

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. 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).

Registrations and other filings

Business registration (state registry / Secretary of State)

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.

Adviser registration (Form ADV)

None of the 2 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.
