The short version

Brian Stemme is listed as a director on 9 SEC Form D filings by 2 issuers between Apr 2010 and Jun 2016: AgeneBio, Inc. (Baltimore, MD — biotechnology — 2010–2013; $4.11M reported sold to 27 investors) and Algaeon, Inc. (Indianapolis, IN — biotechnology — 2014–2016; $771K reported sold to 25 investors).

What this means 2 separate companies raised money with this person listed as director, over about 6 years. Across those companies the filings report $4.88M sold in total.

Listed alongside Michela Gallagher (7 shared filings), Robert Postlethwait (6 shared filings), Timothy F. Parshall (4 shared filings), William Ringo (3 shared filings), Jonathan D. Rosen (2 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 Brian. 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 9 public filings for Brian Stemme and found 7 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

7 differences found between the filings for Brian Stemme (compared 9 filings on Oct 24, 2026)

Note · Jan 7, 2011 – May 19, 2011

Offering amount changed between filings — AgeneBio, Inc.

The Jan 7, 2011 filing says $2,000,000 offered; the May 19, 2011 Form D/A says $5,000,000.

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.

(latest filing Sep 25, 2012) · No amendment in the last 12 months on an offering that may still be open — AgeneBio, Inc. (latest filing Dec 22, 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.

Same name, different state: "Brian Stemme" (OH) is a separate record

This page covers filings where the address state is IN. A separate record, "Brian Stemme" with address state OH, is listed on 3 filings — most recently by Allinaire Therapeutics, LLC (Dec 11, 2018). The two records do not overlap in time: this page runs Apr 12, 2010 to Jun 8, 2016; the other runs Dec 16, 2016 to Dec 11, 2018.

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 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.

Reported revenue range changed between filings — AgeneBio, Inc.

What this means This is the size band the issuer picks for itself on the form. A change can mean the business grew or shrank — or that it chose not to say. Ask for current numbers.

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.

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).

A shared address can mean the same team, a shared office building or a registered agent. It is a lead, not a conclusion.

Registrations and other filings

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.
