The short version

David Barker is listed as a director on 19 SEC Form D filings by 5 issuers between Apr 2009 and Jul 2024: Bionano Genomics, Inc. (San Diego, CA — biotechnology — 2011–2024; $68.4M reported sold to 27 investors), IntegenX Inc (Pleasanton, CA — biotechnology — 2011–2012; $48.8M reported sold to 16 investors), Integrated Diagnostics, Inc. (Seattle, WA — biotechnology — 2014–2016; $31.7M reported sold to 6 investors), CELL BIOSCIENCES INC (Cupertino, CA — biotechnology — 2009–2011; $20M reported sold to 14 investors) and NextBio (Cupertino, CA — industry reported as "Other" — 2009; $6.76M reported sold to 28 investors).

What this means A repeat sponsor — 5 separate companies raised money with this person listed as director, over about 15 years. Across those companies the filings report $175.8M sold in total.

Listed alongside Albert A. Luderer (8 shared filings), James Blair (8 shared filings), Brian Halak (6 shared filings), Tracy Warren (6 shared filings), Blaine Bowman (5 shared filings, management entity) and 53 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.

Public records searched: federal courts (CourtListener / RECAP), SEC enforcement releases, state securities regulators (AZ, CA, DE, TX, WA) — 9 bankruptcy cases matching the name listed in Key records below.

What this means 9 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 19 public filings for David Barker and found 18 differences, 4 worth asking the sponsor about: Amount sold went down between filings; Investor count went down between filings; 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

18 differences found between the filings for David Barker — 4 worth asking about (compared 19 filings on Oct 24, 2026)

Worth asking · Nov 12, 2009 – Dec 21, 2009

Amount sold went down between filings — CELL BIOSCIENCES INC

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.

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 5

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