The short version

Anth is a sponsor group of 27 issuers that PartnerFacts links to one sponsor (shared people, shared management entity, similar issuer names, same person name on both filings, same business address; automatic match from the filings), filing 30 Form D filings between Nov 2023 and Aug 2026.

What this means One team, 27 deal companies, about 3 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: $85.4M to 2,211 investors (latest filing per issuer). Industries as reported: Pooled Investment Fund (27). Issuers are based in NY (25), WA (2).

What this means $85.4M raised across the group, about $39K per investor. Amounts come from each company's latest Form D; they are what the sponsor reported, not audited figures.

Principal people: Jamie Melzer (27 issuers, executive officer), HF Scale Opportunity Fund I GP, LLC (12 issuers, director, entity), Altra FrontierTech Investments GP LLC (9 issuers, director, entity), Altra Venture Opportunity Fund I GP LLC (4 issuers, director, entity), Altra FrontierTech Investments GP LLC (1 issuer, director, entity) and 3 more.

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

Activity: 10 new offerings in the last 12 months; latest filing Aug 27, 2026.

What this means Busy — still raising money this year.

Adviser registration (Form ADV) on record: ALTRA VENTURE PARTNERS LLC.

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 30 public filings for Anth and found 10 differences, 1 worth asking the sponsor about: Altra Venture Partners Fund II GP LLC is no longer listed on the May 22, 2026 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

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 Anth — 1 worth asking about (compared 30 filings on Oct 24, 2026)

Worth asking · Apr 16, 2026 – May 22, 2026

Altra Venture Partners Fund II GP LLC is no longer listed on the May 22, 2026 amendment — Altra Venture Opportunity Fund II LP

Altra Venture Partners Fund II GP LLC appears on the Apr 16, 2026 Form D (executive officer) but not on the May 22, 2026 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 · Nov 18, 2025 – Dec 30, 2025

Form D filed 42 days after the first sale — CRU Fund I, a series of Altra FrontierTech Investments I, LP

The filing says the first sale was Nov 18, 2025. The Form D was filed Dec 30, 2025 — 42 days later. The rule: a Form D is generally due within 15 days after the first sale, so this one is 27 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 · Mar 31, 2025 – May 22, 2025

Form D filed 52 days after the first sale — SPX I, a series of HF Scale Partners II, LP

The filing says the first sale was Mar 31, 2025. The Form D was filed May 22, 2025 — 52 days later. The rule: a Form D is generally due within 15 days after the first sale, so this one is 37 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 24, 2025 – Mar 13, 2025

Form D filed 17 days after the first sale — CORW Fund I, a series of HF Scale Partners II, LP

The filing says the first sale was Feb 24, 2025. The Form D was filed Mar 13, 2025 — 17 days later. The rule: a Form D is generally due within 15 days after the first sale, so this one is 2 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 30, 2026 – Aug 5, 2026

Offering amount changed between filings — PRO Fund I, a series of Altra FrontierTech Investments I, LP

The Apr 30, 2026 filing says $9,147,375 offered; the Aug 5, 2026 Form D/A says $14,231,895.

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 · Sep 30, 2025 – Oct 9, 2025

No amendment in the last 12 months on an offering that may still be open — OAI Fund I, a series of Altra Venture Partners II, LP (latest filing Oct 9, 2025)

The latest filing for this offering is dated Oct 9, 2025 (first sale Sep 30, 2025). It reports $0 sold of $8,548,822 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 · Oct 19, 2023 – Jan 14, 2025

No amendment in the last 12 months on an offering that may still be open — HF Scale Opportunity Fund I LP (latest filing Jan 14, 2025)

The latest filing for this offering is dated Jan 14, 2025 (first sale Oct 19, 2023). It reports $8,405,000 sold of $50,000,000 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.

Note · Sep 24, 2025

Address on file is a registered agent / shared office — ANTH Fund III, a series of Altra Venture Partners II, LP

The latest filing lists 2006 196th St Sw, Suite 114, Lynnwood, WA. That address is used by 3,918 issuers in our index (registered agent / corporate services / fund administrator).

What this means Many small companies use a registered agent's address — it is legal and common. It means the Form D address is not where the team works. Ask where the business operates and who runs it day to day.

Sources
Note · Jan 14, 2025

Address on file is a registered agent / shared office — HF Scale Opportunity Fund I LP

The latest filing lists 119 South Main Street, Suite 220, Seattle, WA. That address is used by 15,451 issuers in our index (registered agent / corporate services / fund administrator).

What this means Many small companies use a registered agent's address — it is legal and common. It means the Form D address is not where the team works. Ask where the business operates and who runs it day to day.

Sources
Note · Mar 19, 2024 – Aug 27, 2026

Member companies list addresses in 2 different states

NY (25), WA (2). 2 members use a registered-agent or shared-office address: HF Scale Opportunity Fund I LP (119 South Main Street, Suite 220, Seattle, WA); ANTH Fund III, a series of Altra Venture Partners II, LP (2006 196th St Sw, Suite 114, Lynnwood, WA).

What this means A registered agent's address is a mailbox, not where the team works. The other address is more likely the real office — ask which one is.

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 all 27 issuers in this group — every filing in our index, latest filing per offering (SEC file number).
