The short version

Diameter is a sponsor group of 29 issuers that PartnerFacts links to one sponsor (shared people, shared management entity, similar issuer names, same business address; automatic match from the filings), filing 64 Form D filings between Aug 2017 and Oct 2026.

What this means One team, 29 deal companies, about 9 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: $8.66B to 1,262 investors (latest filing per issuer). Industries as reported: Pooled Investment Fund (29). Issuers are based in NY (21), Cayman Islands (as filed: E9) (8).

What this means $8.66B raised across the group, about $6.86M per investor. Amounts come from each company's latest Form D; they are what the sponsor reported, not audited figures.

Principal people: Diameter Associates LLC (20 issuers, executive officer and promoter, entity), Diameter Capital Partners LP (20 issuers, executive officer and promoter, entity), Jonathan Lewinsohn (20 issuers, executive officer, director, and promoter), Scott Goodwin (19 issuers, executive officer and promoter), Diameter Principal Finance Partnership LP (8 issuers, executive officer and promoter, entity) and 13 more.

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

Activity: 8 new offerings in the last 12 months; latest filing Oct 13, 2026.

What this means Busy — still raising money this year.

Adviser registration (Form ADV) on record: DIAMETER PRINCIPAL FINANCE LLC; DIAMETER CAPITAL PARTNERS LP.

Public records searched: federal courts (CourtListener / RECAP), SEC enforcement releases, state securities regulators (AK, AL, AR, AZ, CA, CO, CT, DC, DE, FINRA, FL, GA, HI, ID, IL, KS, KY, LA, MA, MD, ME, MI, MO, MS, MT, NASAA, NC, ND, NH, NM, NV, NY, OH, OK, OR, PA, RI, SC, SD, TN, TX, UT, VT, WA, WI, WV, WY), property records (NYC, FL, IL and TX counties) — 1 bankruptcy case matching the name listed in Key records below.

What this means 1 record 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 the newest 50 of 64 public filings for Diameter and found 12 differences, 5 worth asking the sponsor about: Amount sold went down between filings; Investor count went down between filings; 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.

12 differences found between the filings for Diameter — 5 worth asking about (compared the newest 50 of 64 filings on Oct 24, 2026; older filings not covered)

Worth asking · Oct 26, 2020 – Oct 26, 2021

Amount sold went down between filings — Diameter Offshore Fund LP

The Oct 26, 2020 filing says $1,833,750,808 sold; the Oct 26, 2021 Form D/A says $1,007,480,107 sold — $826,270,701 less.

What this means Amounts sold normally only go up as a raise continues. A drop can mean investors were refunded, a figure was corrected, or an earlier number was wrong. Ask the sponsor which it was.

No amendment in the last 12 months on an offering that may still be open — Diameter Credit Co (latest filing Dec 20, 2024) · No amendment in the last 12 months on an offering that may still be open — DLF I LLC (latest filing Oct 2, 2023) · No amendment in the last 12 months on an offering that may still be open — Diameter Dislocation Offshore Fund II LP (latest filing Aug 2, 2023) · No amendment in the last 12 months on an offering that may still be open — Diameter Dislocation Onshore Fund II LP (latest filing Aug 2, 2023)

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

What this means Sponsors often form each deal company in Delaware or Wyoming no matter where the property is. A mix is common; it just tells you which state's rules each company lives under.

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.

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

Business registration (state registry / Secretary of State)

2 of 29 issuers have a matched state registry record — records by status: active 2.

Registries searched: AL (Alabama Secretary of State — Business Entity Records (arc-sos.state.al.us), searched by issuer name, data as of Oct 24, 2026); CO (Colorado Secretary of State — Business Entities in Colorado (data.colorado.gov), data as of Oct 23, 2026); CT (Connecticut Secretary of the State — Business Registry (data.ct.gov), data as of Oct 24, 2026); FL (Florida Department of State, Division of Corporations — quarterly corporate data file (Sunbiz), data as of Oct 7, 2026); NY (New York Department of State — Corporations and Other Entities (data.ny.gov: All Filings + Active Corporations), data as of Oct 20, 2026); OR (Oregon Secretary of State — Active Businesses, All (data.oregon.gov), data as of Oct 20, 2026); PA (Pennsylvania Department of State — Registered Businesses, Current (data.pa.gov), data as of Oct 6, 2026); TX (Texas Comptroller — Active Franchise Taxpayers incl. Secretary of State file data (data.texas.gov), data as of Oct 24, 2026). Registries of other states have not been searched: many publish no bulk file and require a CAPTCHA or bot challenge on their search page, which we do not bypass (Delaware, for example, offers no public bulk file). A registry listing is the state's own record of the entity; it says nothing about the offering itself.
