The short version

Dan Seff is listed as a director on 11 SEC Form D filings by 2 issuers between Jul 2009 and Sep 2024: STAQ Pharma, Inc. (Denver, CO — pharmaceuticals — 2019–2024; $30.3M reported sold to 23 investors) and Sharklet Technologies, Inc. (Aurora, CO — biotechnology — 2009–2012; $2M reported sold to 17 investors).

What this means 2 separate companies raised money with this person listed as director, over about 15 years. Across those companies the filings report $32.3M sold in total.

Listed alongside Joseph W Bagan (11 shared filings), Mark M Spiecker (11 shared filings), Jeffrey L Hval (9 shared filings), Chet Kaczor (8 shared filings), JERROD MILTON (8 shared filings) and 13 others.

What this means These are the other officers, directors or promoters the companies named on the same forms — the team around Dan. 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) — 5 court cases matching the name, 4 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 11 public filings for Dan Seff and found 6 differences: Offering amount changed between filings; 5 offerings have no amendment in the last 12 months and may still be open; 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

6 differences found between the filings for Dan Seff (compared 11 filings on Oct 24, 2026)

Note · Feb 25, 2020 – Apr 7, 2020

The Feb 25, 2020 filing says $8,000,000 offered; the Apr 7, 2020 Form D/A says $9,000,000.

Sources

Offering amount changed between filings — STAQ Pharma, Inc.

The May 3, 2019 filing says $4,000,000 offered; the Feb 25, 2020 Form D/A says $8,000,000.

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 · Jun 23, 2009 – Sep 16, 2024

5 offerings have no amendment in the last 12 months and may still be open

No amendment in the last 12 months on an offering that may still be open — STAQ Pharma, Inc. (latest filing Sep 16, 2024) · No amendment in the last 12 months on an offering that may still be open — STAQ Pharma, Inc. (latest filing Jun 21, 2023) · No amendment in the last 12 months on an offering that may still be open — STAQ Pharma, Inc. (latest filing Dec 23, 2021) · No amendment in the last 12 months on an offering that may still be open — Sharklet Technologies, Inc. (latest filing Dec 18, 2012) · No amendment in the last 12 months on an offering that may still be open — Sharklet Technologies, Inc. (latest filing Jul 7, 2009)

What this means SEC rules expect a yearly amendment while an offering is still going. Ask the sponsor which of these raises have closed.

Sources
Note · Jul 7, 2009 – Dec 18, 2012

Address moved from Alachua, FL to Aurora, CO — Sharklet Technologies, Inc.

The people listed on the Jul 7, 2009 filing give Alachua, FL; on the Dec 18, 2012 filing they give Aurora, CO. The address now on file (12635 E. Montview Blvd., Suite 160, Aurora, CO) is a registered-agent or shared-office address used by 20 issuers.

Sources
Note · Apr 28, 2023 – Jun 21, 2023

Minimum investment changed between filings — STAQ Pharma, Inc.

The Apr 28, 2023 filing lists a minimum of $1,000,000; the Jun 21, 2023 Form D/A lists $100,000.

What this means A different minimum usually means the offering terms changed. Check which terms apply to you.

Sources
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 6 offerings report sales commissions; 0 report finder's fees; 1 reports proceeds to related persons totalling $200,000. (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.

Counted across every filing this person is listed on (latest filing per offering, per issuer).

Adviser registration (Form ADV)

None of the 2 issuers this person is listed on appears in Form ADV (searched 24,962 advisers as of Oct 2, 2026). A person is never an adviser firm; Form ADV is checked for the issuers and the management companies they are listed with.
