The short version

David Seldin is listed as an executive officer, director, and promoter on 54 SEC Form D filings by 29 issuers between Apr 2015 and Oct 2026. Largest by amount reported sold: Anzu Industrial Capital Partners III QP, L.P. (Tampa, FL — pooled investment fund — 2021–2022; $130.4M reported sold to 54 investors), 6K Inc. (North Andover, MA — other technology — 2020–2024; $122.7M reported sold to 24 investors), Anzu Industrial Capital Partners, L.P.

(Rio Rancho, NM — biotechnology — 2020–2026; $44.4M reported sold to 39 investors) and 24 more (all listed below).

What this means That is a lot of deals — 29 separate companies raised money with this person listed as executive officer, director, and promoter, over about 11 years. Across those companies the filings report $710.4M sold in total.

Listed alongside David Michael (32 shared filings), Whitney Haring-Smith (18 shared filings), Thomas R. Nickoloff (11 shared filings), Alexander Koglin (7 shared filings), Michael Humbert (7 shared filings) and 88 others.

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

The issuers belong to 3 sponsor groups: Anzu Industrial (14 issuers, $389.5M reported sold, 2016–2026), Bluestone Life Science Innovation (7 issuers, $19.3M reported sold, 2018–2026) and Amastan (2 issuers, $83.5M reported sold, 2015–2024).

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), state securities regulators (AZ, CA, DE, TX, WA) — 1 bankruptcy case matching the name listed in Key records below. Not yet searched: SEC enforcement releases.

What this means 1 record 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).

Deals 29

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