The short version

Michael Blue is listed as an executive officer and director on 10 SEC Form D filings by 1 issuer between Feb 2017 and Aug 2024: HistoSonics, Inc. (Plymouth, MN — other health care — 2017–2024; $102M reported sold to 44 investors).

What this means One deal on file with the SEC. A Form D is the notice a company files after it starts selling a private investment — it is a notice, not an approval.

Listed alongside Fred Lee (10 shared filings), James Adox (9 shared filings), Tom Tefft (7 shared filings), Andrew Von Eschenbach (5 shared filings), Gerry Brunk (5 shared filings) and 20 others.

What this means These are the other officers, directors or promoters the companies named on the same forms — the team around Michael. Each name links to their own page.

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) — 30 bankruptcy cases matching the name listed in Key records below.

What this means 30 records 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 10 public filings for Michael Blue and found 7 differences: No amendment in the last 12 months on an offering that may still be open; Offering amount changed 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

Comparisons cover issuers and sponsor groups — see the issuer pages under Deals

7 differences found between the filings for Michael Blue (compared 10 filings on Oct 24, 2026)

Note · Jan 30, 2017 – Feb 8, 2017

No amendment in the last 12 months on an offering that may still be open — HistoSonics, Inc. (latest filing Feb 8, 2017)

The latest filing for this offering is dated Feb 8, 2017 (first sale Jan 30, 2017). It reports $8,260,313 sold of $13,260,313 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 · Jul 15, 2014 – Jun 16, 2021

Same name, different state: "Michael Blue" (WA) is a separate record

This page covers filings where the address state is MI or MN. A separate record, "Michael Blue" with address state WA, is listed on 7 filings — most recently by Leafly Holdings, Inc. (Jun 16, 2021). Both records have filings in the same period (Feb 8, 2017 to Apr 11, 2019).

What this means Two records with one name were active at the same time. That can be one person listing different company addresses, or two different people. We keep them apart until a filing ties them together. Check both pages before you decide.

Note · Apr 11, 2019 – Apr 30, 2020

Address moved from Ann Arbor, MI to Plymouth, MN — HistoSonics, Inc.

The people listed on the Apr 11, 2019 filing give Ann Arbor, MI; on the Apr 30, 2020 filing they give Plymouth, MN.

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.

Note · Feb 8, 2017 – Aug 15, 2024

Michael Blue is listed with 2 different address states: MI, MN

MI on 6 filings (Feb 8, 2017 to Apr 11, 2019); MN on 4 filings (Apr 30, 2020 to Aug 15, 2024).

What this means The address on a Form D is usually the company's, not the person's home, so this often just reflects different companies. It can also mean a move. Nothing wrong by itself.

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).

Registrations and other filings

Business registration (state registry / Secretary of State)

Individuals are not matched to business registrations — registries list companies, and a name alone is not enough to tie a person to one. Officers and managers appear by name inside each matched company's record on the issuer pages. 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).

Adviser registration (Form ADV)

None of the 1 issuer 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.

Other offering types (Regulation A and Regulation Crowdfunding)

Searched SEC Regulation A Data Sets (Forms 1-A, 1-K, 1-Z; 2015 Q2 → 2026 Q3); SEC Crowdfunding Offerings Data Sets (Form C family; 2016 Q2 → 2026 Q3); EDGAR form index for 2026 Q3 → 2026 Q4 (51,358 records as of Oct 23, 2026, 8:41 PM ET) — nothing matched this name.

Property records none — individuals are not matched

Property records are matched to companies only, never to individuals, so none are matched to Michael Blue by design. Searched property records in Hillsborough County FL (Clerk recorded-document index Oct 14, 2026 to Oct 15, 2026 + FL DOR 2026 ownership roll), Miami-Dade County FL (FL DOR 2026 ownership roll), Harris County TX (HCAD 2026 ownership roll), Dallas County TX (DCAD 2026 ownership roll), New York City ACRIS documents and PLUTO ownership rows already retrieved for other issuers, Cook County IL sale and ownership rows already retrieved for other issuers (814,874 records as of Oct 23, 2026, 8:59 PM ET) for the 1 issuer this person is listed on — nothing matched.
