The short version

Listed alongside Michael Stocum (8 shared filings), Steven Soper (8 shared filings), Sam Tetlow (7 shared filings), Judy Muller-Cohn (6 shared filings), Philip D. Buchanan (6 shared filings) and 3 others.

What this means These are the other officers, directors or promoters the companies named on the same forms — the team around Rolf. 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 11 public filings for Rolf Muller and found 3 differences: 5 offerings have no amendment in the last 12 months and may still be open; Address moved from Chapel Hill, NC to San Diego, CA; 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

3 differences found between the filings for Rolf Muller (compared 11 filings on Oct 24, 2026)

Note · Feb 11, 2011 – Dec 2, 2021

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 — BioFluidica, Inc. (latest filing Dec 2, 2021) · No amendment in the last 12 months on an offering that may still be open — BioFluidica, Inc. (latest filing Mar 29, 2021) · No amendment in the last 12 months on an offering that may still be open — BioFluidica, Inc. (latest filing Jul 27, 2017) · No amendment in the last 12 months on an offering that may still be open — Biomatrica, Inc. (latest filing Sep 1, 2011) · No amendment in the last 12 months on an offering that may still be open — Biomatrica, Inc. (latest filing Feb 15, 2011)

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 27, 2017 – Sep 13, 2018

Address moved from Chapel Hill, NC to San Diego, CA — BioFluidica, Inc.

The people listed on the Jul 27, 2017 filing give Chapel Hill, NC; on the Sep 13, 2018 filing they give San Diego, 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.

Sources
Note · Feb 15, 2011 – Dec 2, 2021

Rolf Muller is listed with 2 different address states: CA, NC

CA on 8 filings (Feb 15, 2011 to Dec 2, 2021); NC on 3 filings (Apr 18, 2016 to Jul 27, 2017).

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.

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.

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 2
