The short version

John MacDonald is listed as an executive officer and director on 4 SEC Form D filings by 3 issuers between Dec 2017 and Jul 2021: Pi Inc. (San Bruno, CA — other technology — 2017; $11.9M reported sold to 10 investors), Tychon Biosciences LLC (Minneapolis, MN — other technology — 2018; $471K reported sold to 7 investors) and MARTELL DIAGNOSTIC LABORATORIES, INC. (Roseville, MN — biotechnology — 2018–2021; $365K reported sold to 4 investors).

What this means A repeat sponsor — 3 separate companies raised money with this person listed as executive officer and director, over about 4 years. Across those companies the filings report $12.8M sold in total.

Listed alongside Arkadiusz Dudek (2 shared filings), Franklin Pass (2 shared filings), Mark Greene (2 shared filings), Steven P. Stoesz (2 shared filings), Arek Z. Dudek, MD PhD (1 shared filing) and 10 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 Invenshure (6 issuers, $13.2M reported sold, 2012–2020).

What this means A sponsor group is one team that sets up a new company for each deal. Invenshure has 6 companies on file and $13.2M reported sold in total — the group page shows the whole track record in one place.

Public records searched: federal courts (CourtListener / RECAP), state securities regulators (AZ, CA, DE, TX, WA) — 11 bankruptcy cases matching the name listed in Key records below. Not yet searched: SEC enforcement releases.

What this means 11 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.

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).
