The short version

Elixirgen is a sponsor group of 2 issuers that PartnerFacts links to one sponsor (shared people, same business address, similar issuer names; automatic match from the filings), filing 10 Form D filings between Apr 2012 and Nov 2025.

What this means One team, 2 deal companies, about 13 years of track record in SEC filings. We link the companies because the same people or address appear on their forms — tap "Request a correction" if that is wrong.

Combined reported sold: $4.3M to 6 investors (latest filing per issuer). Industries as reported: Biotechnology (2). Issuers are based in MD (2).

What this means $4.3M raised across the group, about $717K per investor. Amounts come from each company's latest Form D; they are what the sponsor reported, not audited figures.

Principal people: Minoru Ko (2 issuers, executive officer and director), Akihiro KO (1 issuer, executive officer, director, and promoter), Hiroaki Kobayashi (1 issuer, director), Jeffrey Cleland (1 issuer, director), Maiko Katadae (1 issuer, director) and 4 more.

What this means The person on the most companies is usually the one running the show; their page lists every deal.

Activity: 1 new offering in the last 12 months; latest filing Nov 13, 2025.

What this means still raising money this year.

Public records searched: federal courts (CourtListener / RECAP), SEC enforcement releases, state securities regulators (AZ, CA, DE, TX, WA), property records (NYC, FL, IL and TX counties) — none found.

What this means Nothing turned up where we looked (4 sources). That does not prove there is nothing — it means none was found in those sources on that date.

We compared 10 public filings for Elixirgen and found 10 differences: Form D filed 22 days after the first sale; Form D filed 16 days after the first sale; 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

No comparisons published

What is compared

No public statement by this sponsor group has been collected yet, so there is nothing to compare. Sources compared: the sponsor's own website (known from the issuer's own filings — Form C issuer website, EDGAR company profile — an approved profile claim or Form ADV Item 1.I of its matched adviser) · SEC Form D · SEC Form ADV (IAPD) · Internet Archive · No website is on file for this sponsor group yet.

10 differences found between the filings for Elixirgen (compared 10 filings on Oct 24, 2026)

Note · Nov 9, 2023 – Dec 1, 2023

Form D filed 22 days after the first sale — ELIXIRGEN THERAPEUTICS, INC.

The filing says the first sale was Nov 9, 2023. The Form D was filed Dec 1, 2023 — 22 days later. The rule: a Form D is generally due within 15 days after the first sale, so this one is 7 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 2, 2021 – Feb 18, 2021

Form D filed 16 days after the first sale — ELIXIRGEN THERAPEUTICS, INC.

The filing says the first sale was Feb 2, 2021. The Form D was filed Feb 18, 2021 — 16 days later. The rule: a Form D is generally due within 15 days after the first sale, so this one is 1 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 7, 2012 – Apr 23, 2012

Form D filed 16 days after the first sale — Elixirgen, LLC

The filing says the first sale was Apr 7, 2012. The Form D was filed Apr 23, 2012 — 16 days later. The rule: a Form D is generally due within 15 days after the first sale, so this one is 1 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.

Note · Feb 18, 2021 – Dec 1, 2023

4 role changes for the same people across filings

Minoru Ko's role changed at ELIXIRGEN THERAPEUTICS, INC.: executive officer, director → director · AKIHIRO KO's role changed at ELIXIRGEN THERAPEUTICS, INC.: executive officer, director, promoter → executive officer, director · Minoru Ko's role changed at ELIXIRGEN THERAPEUTICS, INC.: director → executive officer, director · AKIHIRO KO's role changed at ELIXIRGEN THERAPEUTICS, INC.: executive officer, director → executive officer, director, promoter

What this means Roles on Form D are self-reported. Ask who runs the company today.

Sources
Note · Dec 2, 2019 – Aug 17, 2020

Offering amount changed between filings — ELIXIRGEN THERAPEUTICS, INC.

The Dec 2, 2019 filing says $5,006,900 offered; the Aug 17, 2020 Form D/A says $5,706,889.

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 · Feb 2, 2021 – Feb 18, 2021

No amendment in the last 12 months on an offering that may still be open — ELIXIRGEN THERAPEUTICS, INC. (latest filing Feb 18, 2021)

The latest filing for this offering is dated Feb 18, 2021 (first sale Feb 2, 2021). It reports $4,199,985 sold of $5,499,971 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 7, 2012 – Apr 23, 2012

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 all 2 issuers in this group — every filing in our index, latest filing per offering (SEC file number).
