The short version

Richard Stack is listed as a director on 2 SEC Form D filings by 1 issuer between Aug 2009 and Sep 2009: BAROSENSE INC (Redwood City, CA — biotechnology — 2009; $29.5M reported sold to 31 investors).

What this means One deal on file with the SEC, filed Sep 2009. A Form D is the notice a company files after it starts selling a private investment — it is a notice, not an approval.

Listed alongside Alan Levy (2 shared filings), Daniel J. Balbierz (2 shared filings), Eric Linsley (2 shared filings), Gregory A. Barrett (2 shared filings) and John Onopchenko (2 shared filings).

What this means These are the other officers, directors or promoters the companies named on the same forms — the team around Richard. 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) — 1 court case matching the name, 20 bankruptcy cases matching the name listed in Key records below.

What this means 21 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 2 public filings for Richard Stack and found 2 differences: No amendment in the last 12 months on an offering that may still be open; Same name, different state: "Richard S. Stack" (NC) is a separate record.

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

2 differences found between the filings for Richard Stack (compared 2 filings on Oct 24, 2026)

Note · Aug 13, 2009 – Sep 24, 2009

No amendment in the last 12 months on an offering that may still be open — BAROSENSE INC (latest filing Sep 24, 2009)

The latest filing for this offering is dated Sep 24, 2009 (first sale Aug 13, 2009). It reports $29,485,394 sold of $30,552,784 offered. No later amendment is in our index as of Oct 24, 2026.

What this means SEC rules expect a yearly amendment while an offering is still going. The raise may simply have ended — a Form D does not say when it closed. Ask the sponsor whether the offering closed, when, and at what amount.

Form D/A · Sep 24, 2009 ↗BAROSENSE INC — PartnerFacts page ↗
Sources
Note · Sep 2, 2010

Same name, different state: "Richard S. Stack" (NC) is a separate record

This page covers filings where the address state is CA. A separate record, "Richard S. Stack" with address state NC, is listed on 1 filing — most recently by SYNECOR LLC (Sep 2, 2010). The two records do not overlap in time: this page runs Aug 21, 2009 to Sep 24, 2009; the other has one filing dated Sep 2, 2010.

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.

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

0 of 1 offering report sales commissions; 1 reports finder's fees totalling $285,000; 0 report proceeds to related persons. (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.
