The short version

Jan Garfinkle is listed as an executive officer and director on 44 SEC Form D filings by 15 issuers between Apr 2009 and Dec 2024. Largest by amount reported sold: Arboretum Ventures III, L.P. (Ann Arbor, MI — pooled investment fund — 2011; $136.8M reported sold to 69 investors), Arbor Bancorp, Inc. (Ann Arbor, MI — commercial banking — 2016–2021; $75M reported sold to 73 investors), Francis Medical, Inc. (Maple Grove, MN — other health care — 2018–2024; $40M reported sold to 18 investors), NXTHERA INC (Maple Grove, MN — other health care — 2009–2017; $25M reported sold to 31 investors), SONITUS MEDICAL INC (San Mateo, CA — other technology — 2011–2014; $25M reported sold to 21 investors) and 10 more (all listed below).

What this means That is a lot of deals — 15 separate companies raised money with this person listed as executive officer and director, over about 15 years. Across those companies the filings report $388.3M sold in total.

Listed alongside Sami Hamade (19 shared filings), Michael Hoey (18 shared filings), Andre de Bruin (17 shared filings), J. Robert Paulson (14 shared filings), Jeffrey Williams (11 shared filings) and 91 others.

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

The issuers belong to 3 sponsor groups: Arboretum (3 issuers, $136.8M reported sold, 2011–2019), Nxthera (2 issuers, $60.6M reported sold, 2009–2024) and Tangent (2 issuers, $7.15M reported sold, 2011–2024).

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) — none found.

What this means Nothing turned up where we looked (3 sources). That does not prove there is nothing — it means none was found in those sources on that date.

We compared 44 public filings for Jan Garfinkle and found 9 differences: 4 Form Ds were filed more than 15 days after the first sale; Jan Garfinkle's role changed at SONITUS MEDICAL INC: executive officer → director; 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

9 differences found between the filings for Jan Garfinkle (compared 44 filings on Oct 24, 2026)

Note · Mar 28, 2011 – Sep 10, 2021

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

Form D filed 22 days after the first sale — RareCyte, Inc. · Form D filed 21 days after the first sale — NXTHERA INC · Form D filed 18 days after the first sale — SONITUS MEDICAL INC · Form D filed 16 days after the first sale — SONITUS TECHNOLOGIES INC.

What this means Late notices are common and carry no penalty by themselves. A pattern of late paperwork is worth asking the sponsor about.

Jan Garfinkle's role changed at SONITUS MEDICAL INC: executive officer → director

The Apr 11, 2011 filing lists Jan Garfinkle as executive officer; the May 23, 2012 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.

What this means Targets change as deals grow or shrink. Ask whether later money has the same terms.

No amendment in the last 12 months on an offering that may still be open — Francis Medical, Inc. (latest filing Dec 31, 2024) · No amendment in the last 12 months on an offering that may still be open — Strata Oncology, Inc. (latest filing Nov 22, 2024) · No amendment in the last 12 months on an offering that may still be open — RareCyte, Inc.

(latest filing Sep 29, 2021) · No amendment in the last 12 months on an offering that may still be open — Strata Oncology, Inc. (latest filing Nov 4, 2020) · and 13 more

What this means SEC rules expect a yearly amendment while an offering is still going. Ask the sponsor which of these raises have closed.

Jan Garfinkle is written 2 different ways on the filings

listed as "Jan Garfinkle" on 37 filings (from Apr 30, 2009), and "Jan L. Garfinkle" on 7 filings (from Feb 9, 2011).

What this means Same person, written differently — a middle name or suffix left off, or spelled another way. It is normal, but check that the full legal name matches your subscription documents.

Industry group changed between filings — NXTHERA INC

"Other" (Nov 17, 2009 to Mar 3, 2017); then "Other Health Care" (Jul 19, 2017).

What this means The issuer described its business differently on different forms. Often it is just a different box ticked; sometimes the deal itself changed. Ask which business your money is in.

Same name, different state: "Jan Garfinkle" (MA) is a separate record

This page covers filings where the address state is WA or MI or CA or MN. A separate record, "Jan Garfinkle" with address state MA, is listed on 4 filings — most recently by Reprieve Cardiovascular, Inc. (Jun 5, 2025). Both records have filings in the same period (Nov 20, 2023 to Nov 22, 2024).

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.

Address moved from St. Paul, MN to Maple Grove, MN — NXTHERA INC

The people listed on the Aug 31, 2011 filing give St. Paul, MN; on the Apr 11, 2013 filing they give Maple Grove, MN.

What this means Businesses move; this just shows the two places and dates. If you were told one city and the forms say another, ask which is current.

Note · Apr 30, 2009 – Dec 31, 2024

Jan Garfinkle is listed with 4 different address states: WA, MI, CA, MN

WA on 3 filings (Apr 30, 2009 to Jul 25, 2023); MI on 35 filings (Nov 17, 2009 to Nov 22, 2024); CA on 2 filings (Apr 28, 2014 to Dec 30, 2020); MN on 4 filings (Nov 29, 2018 to Dec 31, 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. 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 15

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