The short version

Michael Zak is listed as a director on 6 SEC Form D filings by 3 issuers between Apr 2009 and Nov 2015: RIVE TECHNOLOGY INC (Monmouth Junction, NJ — other technology — 2013–2015; $25M reported sold to 13 investors), VERENIUM CORP (San Diego, CA — biotechnology — 2009–2012; $13.7M reported sold to 8 investors) and Reva Systems Corp (Chelmsford, MA — computers — 2009; $5M reported sold to 11 investors).

Listed alongside Cheryl Wenzinger (3 shared filings), JAMES LEVINE (3 shared filings), James H. Cavanaugh (3 shared filings), Janet Roemer (3 shared filings), Jeffrey Black (3 shared filings) and 28 others.

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

Public records searched: federal courts (CourtListener / RECAP), state securities regulators (AZ, CA, DE, TX, WA) — 6 bankruptcy cases matching the name listed in Key records below. Not yet searched: SEC enforcement releases.

What this means 6 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.

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).
