(Ithaca, NY — other technology — 2019; $5.01M reported sold to 48 investors).

Listed alongside Ian Jacobs (3 shared filings), Alex A. Behfar (1 shared filing), James R. Shealy (1 shared filing), Michael O. Thompson (1 shared filing), Richard J. Brown (1 shared filing) and 1 others.

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

1 of the issuers belongs to the sponsor group Exicure (2 issuers, $36.8M reported sold, 2012–2018).

What this means A sponsor group is one team that sets up a new company for each deal. Exicure has 2 companies on file and $36.8M 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, CT, DE, FINRA, GA, HI, ID, IL, KS, KY, LA, MA, MD, ME, MI, MO, MS, MT, NASAA, NC, ND, NH, NM, NV, OK, OR, PA, RI, SC, SD, TN, TX, VT, WA, WI, WV, WY) — 12 bankruptcy cases matching the name listed in Key records below.

What this means 12 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 3 public filings for Mark N. Tompkins and found 5 differences, 1 worth asking the sponsor about: Bankruptcy case: Mark Tompkins; 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

5 differences found between the filings for Mark N. Tompkins — 1 worth asking about (compared 3 filings on Oct 24, 2026)

Worth asking · May 12, 2026

Bankruptcy case: Mark Tompkins — filed May 12, 2026

United States Bankruptcy Court, S.D. New York docket "Mark Tompkins" filed May 12, 2026 (Open). Mark N. Tompkins is listed as Debtor ("Mark Tompkins"). Our match estimate: 50%.

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.

Sources
Note · Feb 27, 2024

Mark N. Tompkins appears on 1 deal that stopped filing before reaching its target

Odyssey Semiconductor Technologies, Inc. (last filing Feb 27, 2024; $5,006,500 sold of $12,000,000). Each has no filing in more than two years and reported under half its target sold.

What this means An issuer whose last filing is more than two years old and reported under half its target sold. The raise may have closed early or quietly stopped. Ask what happened to each.

Sources
Note · Jun 16, 2017 – Jul 3, 2017

Form D filed 17 days after the first sale — EXICURE, INC.

The filing says the first sale was Jun 16, 2017. The Form D was filed Jul 3, 2017 — 17 days later. The rule: a Form D is generally due within 15 days after the first sale, so this one is 2 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.

Sources
Note · Jun 21, 2019 – Jul 3, 2019

No amendment in the last 12 months on an offering that may still be open — Odyssey Semiconductor Technologies, Inc. (latest filing Jul 3, 2019)

The latest filing for this offering is dated Jul 3, 2019 (first sale Jun 21, 2019). It reports $2,502,018 sold of $3,500,000 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.

Sources
Note · Jul 3, 2017 – Jul 3, 2019

Mark N. Tompkins is written 2 different ways on the filings

listed as "Mark Tompkins" on the Jul 3, 2017 filing, and "Mark N. Tompkins" on 2 filings (from Jul 3, 2019).

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.

Sources
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.

5. Money to insiders

2 of 3 offerings report sales commissions totalling $851,195; 0 report finder's fees; 0 report proceeds to related persons. (includes amounts the issuer reported as estimates)

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).
