The short version

John McCallum is listed as a director on 14 SEC Form D filings by 3 issuers between Sep 2013 and Oct 2026: Provisio Medical, Inc. (San Diego, CA — other technology — 2022–2025; $11.3M reported sold to 53 investors), Vivex Biomedical, Inc. (Atlanta, GA — biotechnology — 2013–2017; $7.24M reported sold to 51 investors) and Provisio Medical Technologies Corp (San Diego, CA — other technology — 2025–2026; $3.55M reported sold to 14 investors).

What this means A repeat sponsor — 3 separate companies raised money with this person listed as director, over about 13 years. Across those companies the filings report $22.1M sold in total.

Listed alongside Michael Chobotov (10 shared filings), Stephen Eric Ryan (10 shared filings), Aurelio Fernandez (7 shared filings), Christopher Carcerano (5 shared filings), Frank J. Del Rio (4 shared filings) and 25 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.

2 of the issuers belong to the sponsor group Provisio Medical (2 issuers, $4.31M reported sold, 2016–2026).

What this means A sponsor group is one team that sets up a new company for each deal. Provisio Medical has 2 companies on file and $4.31M 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) — 3 court cases matching the name, 20 bankruptcy cases matching the name listed in Key records below.

What this means 23 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 14 public filings for John McCallum and found 10 differences, 1 worth asking the sponsor about: 9 filings report more than 10% of the money raised going to insiders; 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.

"$1 - $1,000,000" (Jul 18, 2013); then "$1,000,001 - $5,000,000" (Sep 16, 2013); then "$25,000,001 - $100,000,000" (Jan 5, 2016).

What this means This is the size band the issuer picks for itself on the form. A change can mean the business grew or shrank — or that it chose not to say. Ask for current numbers.

Note · Jun 25, 2010 – Jun 15, 2011

Same name, different state: "John McCallum" (FL) is a separate record

This page covers filings where the address state is GA or CA. A separate record, "John McCallum" with address state FL, is listed on 4 filings — most recently by AXOGEN CORP (Jun 15, 2011). The two records do not overlap in time: this page runs Sep 16, 2013 to Oct 22, 2026; the other runs Jun 25, 2010 to Jun 15, 2011.

What this means Could be the same person who moved, or two people with the same name. We keep them apart until a filing ties them together. Check both pages before you decide.

Address moved from Marietta, GA to Atlanta, GA — Vivex Biomedical, Inc.

The people listed on the Jan 5, 2016 filing give Marietta, GA; on the Jan 26, 2017 filing they give Atlanta, GA.

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 · Sep 16, 2013 – Oct 22, 2026

John McCallum is listed with 2 different address states: GA, CA

GA on 13 filings (Sep 16, 2013 to Oct 22, 2026); CA on 1 filing (Nov 25, 2022).

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.

5. Money to insiders

3 of 11 offerings report sales commissions totalling $411,000; 1 reports finder's fees totalling $100,000; 9 report proceeds to related persons totalling $5,450,000. (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).

Deals 3

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

Issuers are grouped when their Form D filings share related persons, a management entity or a business address (automatic match from the filings). "Listed" marks the issuers that name John McCallum.

Same business address

2 other issuers file from the same address

A shared address can mean the same team, a shared office building or a registered agent. It is a lead, not a conclusion.

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. Secretary of State file data (data.texas.gov), data as of Oct 24, 2026). Registries of other states have not been searched: many publish no bulk file and require a CAPTCHA or bot challenge on their search page, which we do not bypass (Delaware, for example, offers no public bulk file).

Adviser registration (Form ADV)

None of the 3 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)

Searched SEC Regulation A Data Sets (Forms 1-A, 1-K, 1-Z; 2015 Q2 → 2026 Q3); SEC Crowdfunding Offerings Data Sets (Form C family; 2016 Q2 → 2026 Q3); EDGAR form index for 2026 Q3 → 2026 Q4 (51,358 records as of Oct 23, 2026, 8:41 PM ET) — nothing matched this name.

Property records none — individuals are not matched

Property records are matched to companies only, never to individuals, so none are matched to John McCallum by design. Searched property records in Hillsborough County FL (Clerk recorded-document index Oct 14, 2026 to Oct 15, 2026 + FL DOR 2026 ownership roll), Miami-Dade County FL (FL DOR 2026 ownership roll), Harris County TX (HCAD 2026 ownership roll), Dallas County TX (DCAD 2026 ownership roll), New York City ACRIS documents and PLUTO ownership rows already retrieved for other issuers, Cook County IL sale and ownership rows already retrieved for other issuers (814,874 records as of Oct 23, 2026, 8:59 PM ET) for the 3 issuers this person is listed on — nothing matched.
