The short version

Sunstone Boom is a sponsor group of 16 issuers that PartnerFacts links to one sponsor (shared people, same business address, similar issuer names; automatic match from the filings), filing 16 Form D filings in Aug 2022.

What this means One team, 16 deal companies. 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: $13.6M to 111 investors (latest filing per issuer). Industries as reported: Pooled Investment Fund (16). Issuers are based in CA (16).

What this means $13.6M raised across the group, about $122K per investor. Amounts come from each company's latest Form D; they are what the sponsor reported, not audited figures.

Principal people: Michael Stone (16 issuers, executive officer).

What this means 16 deals for a one-person team on paper. The person on the most companies is usually the one running the show; their page lists every deal.

Activity: 0 new offerings in the last 12 months; latest filing Aug 22, 2022.

What this means No new raise filed in the past year.

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) — 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 16 public filings for Sunstone Boom and found 5 differences, 2 worth asking the sponsor about: 107 other issuers file from the same address; 16 Form Ds were filed more than 15 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.

5 differences found between the filings for Sunstone Boom — 2 worth asking about (compared 16 filings on Oct 24, 2026)

107 other issuers file from the same address — 15 member issuers (LBA Sunstone Fund II, LP; Sunstone Horizon Fund I, LP; Sunstone Horizon Fund II, LP; …)

The address on file, 18881 Von Karman Ave, Suite 1000, Irvine, CA, is used by 122 issuers in our index across 4 sponsor groups; 107 are outside this group. It is not on our registered-agent list, so it may be a shared office or administrator.

What this means Many unrelated companies file from this address. Often a registered agent or a fund administrator; sometimes a shared office. Ask where the team actually works.

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

Business registration (state registry / Secretary of State)

None of the 16 issuers has a record in the registries searched.

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.
