The short version

Stan Sewitch is listed as a director on 6 SEC Form D filings by 4 issuers between Mar 2010 and Apr 2013: Ridge Diagnostics, Inc. (La Jolla, CA — biotechnology — 2010–2013; $6.61M reported sold to 32 investors), BIOSURPLUS, INC. (San Diego, CA — industry reported as "Other" — 2012; $2.4M reported sold to 2 investors), BeamOne LLC (San Diego, CA — industry reported as "Other" — 2010; $450K reported sold to 6 investors) and Sabia, Inc (San Diego, CA — other technology — 2012; $295K reported sold to 2 investors).

What this means A repeat sponsor — 4 separate companies raised money with this person listed as director, over about 3 years. Across those companies the filings report $9.75M sold in total.

Listed alongside Charles J. Cashion (3 shared filings), David F. Hale (3 shared filings), Karen A. Klause (3 shared filings), Lonna J. Williams (3 shared filings), David Vandertie (2 shared filings) and 19 others.

What this means These are the other officers, directors or promoters the companies named on the same forms — the team around Stan. 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) — none found.

What this means Nothing turned up where we looked (3 sources). That does not prove there is nothing — it means none was found in those sources on that date.

We compared 6 public filings for Stan Sewitch and found 10 differences, 2 worth asking the sponsor about: Form D filed 126 days after the first sale; Stan Sewitch is no longer listed on the Jul 2, 2012 amendment; 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

10 differences found between the filings for Stan Sewitch — 2 worth asking about (compared 6 filings on Oct 24, 2026)

Worth asking · Apr 17, 2012 – Aug 21, 2012

Form D filed 126 days after the first sale — Sabia, Inc

The filing says the first sale was Apr 17, 2012. The Form D was filed Aug 21, 2012 — 126 days later. The rule: a Form D is generally due within 15 days after the first sale, so this one is 111 days past that.

What this means A late notice is common and carries no penalty by itself. It is worth asking the sponsor why the paperwork lagged.

Sources
Worth asking · Apr 3, 2012 – Jul 2, 2012

Stan Sewitch is no longer listed on the Jul 2, 2012 amendment — BIOSURPLUS, INC.

Stan Sewitch appears on the Apr 3, 2012 Form D (director) but not on the Jul 2, 2012 Form D/A for the same offering.

What this means People leave, and the issuer must list only current officers, directors and promoters. It is still worth asking why this person left and who replaced them.

Sources
Note · May 7, 2010 – Jun 11, 2010

Form D filed 35 days after the first sale — Ridge Diagnostics, Inc.

The filing says the first sale was May 7, 2010. The Form D was filed Jun 11, 2010 — 35 days later. The rule: a Form D is generally due within 15 days after the first sale, so this one is 20 days past that.

What this means A late notice is common and carries no penalty by itself. It is worth asking the sponsor why the paperwork lagged.

Sources
Note · Feb 7, 2010 – Mar 23, 2010

Form D filed 44 days after the first sale — BeamOne LLC

The filing says the first sale was Feb 7, 2010. The Form D was filed Mar 23, 2010 — 44 days later. The rule: a Form D is generally due within 15 days after the first sale, so this one is 29 days past that.

What this means A late notice is common and carries no penalty by itself. It is worth asking the sponsor why the paperwork lagged.

Sources
Note · Apr 3, 2012 – Jul 2, 2012

Offering amount changed between filings — BIOSURPLUS, INC.

The Apr 3, 2012 filing says $1,500,000 offered; the Jul 2, 2012 Form D/A says $2,400,000.

What this means The target raise changed. Raising the cap is common when a deal grows; ask whether the extra money has the same terms and use.

Sources
Note · Apr 5, 2013 – Apr 18, 2013

No amendment in the last 12 months on an offering that may still be open — Ridge Diagnostics, Inc. (latest filing Apr 18, 2013)

The latest filing for this offering is dated Apr 18, 2013 (first sale Apr 5, 2013). It reports $250,000 sold of $2,500,000 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.

Sources
Note · Apr 17, 2012 – Aug 21, 2012

No amendment in the last 12 months on an offering that may still be open — Sabia, Inc (latest filing Aug 21, 2012)

Note · Mar 19, 2012 – Apr 18, 2013

Address moved from San Diego, CA to La Jolla, CA — Ridge Diagnostics, Inc.

The people listed on the Mar 19, 2012 filing give San Diego, CA; on the Apr 18, 2013 filing they give La Jolla, CA.

What this means Businesses move; this just shows the two places and dates. If you were told one city and the forms say another, ask which is current.

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).
