The short version

Ben Auspitz is listed as a director on 15 SEC Form D filings by 6 issuers between Jun 2011 and Aug 2026. Largest by amount reported sold: Compass Therapeutics LLC (Cambridge, MA — biotechnology — 2015–2018; $110.2M reported sold to 20 investors), Unum Therapeutics Inc. (Cambridge, MA — biotechnology — 2014–2015; $104.4M reported sold to 22 investors), Checkmate Pharmaceuticals, Inc. (Cambridge, MA — biotechnology — 2017–2019; $85.1M reported sold to 17 investors), Ultragenyx Pharmaceutical Inc. (Novato, CA — biotechnology — 2011–2012; $75M reported sold to 34 investors), Prana Therapies, Inc. (Encinitas, CA — biotechnology — 2026; $40.2M reported sold to 9 investors) and 1 more (all listed below).

What this means A repeat sponsor — 6 separate companies raised money with this person listed as director, over about 15 years. Across those companies the filings report $420.9M sold in total.

Listed alongside Carl L. Gordon (4 shared filings), Charles Yon (4 shared filings), Corey Goodman (4 shared filings), Errik Anderson (4 shared filings), Michael Powell (4 shared filings) and 48 others.

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

The issuers belong to 2 sponsor groups: Compass Therapeutics (2 issuers, $170.7M reported sold, 2014–2020) and Antlia (2 issuers, $6.56M reported sold, 2020–2026).

What this means This person is listed across more than one sponsor team; each group page shows that team's full track record.

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) — none found.

What this means Nothing turned up where we looked (3 sources). That does not prove there is nothing — it means none was found in those sources on that date.

We compared 15 public filings for Ben Auspitz and found 14 differences, 2 worth asking the sponsor about: Form D filed 258 days after the first sale; Ben Auspitz is no longer listed on the Jan 28, 2020 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

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

14 differences found between the filings for Ben Auspitz — 2 worth asking about (compared 15 filings on Oct 24, 2026)

Note · Dec 15, 2003 – Apr 29, 2005

Bankruptcy case: Charles E. Yon — filed Dec 15, 2003

United States Bankruptcy Court, D. Massachusetts docket "Charles E. Yon" filed Dec 15, 2003, closed Apr 29, 2005. Charles Yon (listed on the same filings) is listed as Debtor ("Charles E. Yon"). Our match estimate: 70%.

What this means A bankruptcy filing was found. Many are old or personal and have nothing to do with the deal — but ask what it was and when it closed.

Worth asking · Nov 25, 2025 – Aug 10, 2026

Form D filed 258 days after the first sale — Prana Therapies, Inc.

The filing says the first sale was Nov 25, 2025. The Form D was filed Aug 10, 2026 — 258 days later. The rule: a Form D is generally due within 15 days after the first sale, so this one is 243 days past that.

What this means The notice went in months after money was taken in. Late notices are common and carry no penalty by themselves, but it is fair to ask the sponsor why the paperwork lagged.

Sources
Note · Dec 22, 2017 – Jan 8, 2018

Form D filed 17 days after the first sale — Compass Therapeutics LLC

The filing says the first sale was Dec 22, 2017. The Form D was filed Jan 8, 2018 — 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 · Oct 3, 2014 – Oct 20, 2014

Form D filed 17 days after the first sale — Unum Therapeutics Inc.

The filing says the first sale was Oct 3, 2014. The Form D was filed Oct 20, 2014 — 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.

5 offerings have no amendment in the last 12 months and may still be open

No amendment in the last 12 months on an offering that may still be open — Compass Therapeutics LLC (latest filing Jul 16, 2018) · No amendment in the last 12 months on an offering that may still be open — Compass Therapeutics LLC (latest filing Jan 8, 2018) · No amendment in the last 12 months on an offering that may still be open — Unum Therapeutics Inc. (latest filing Oct 20, 2014) · No amendment in the last 12 months on an offering that may still be open — Ultragenyx Pharmaceutical Inc. (latest filing Jul 30, 2012) · No amendment in the last 12 months on an offering that may still be open — Ultragenyx Pharmaceutical Inc. (latest filing Jun 23, 2011)

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

Sources
Worth asking · Aug 20, 2019 – Jan 28, 2020

Ben Auspitz is no longer listed on the Jan 28, 2020 amendment — Checkmate Pharmaceuticals, Inc.

Ben Auspitz appears on the Aug 20, 2019 Form D (director) but not on the Jan 28, 2020 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 · Jul 1, 2015 – Sep 21, 2016

Offering amount changed between filings — Compass Therapeutics LLC

The Jul 1, 2015 filing says $120,977,535 offered; the Sep 21, 2016 Form D/A says $170,205,999.

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 · Oct 20, 2014 – Jun 25, 2015

Industry group changed between filings — Unum Therapeutics Inc.

"Other Health Care" (Oct 20, 2014); then "Biotechnology" (Jun 25, 2015).

What this means The issuer described its business differently on different forms. Often it is just a different box ticked; sometimes the deal itself changed. Ask which business your money is in.

Address moved from Hanover, NH to Cambridge, MA — Compass Therapeutics LLC

The people listed on the Jul 1, 2015 filing give Hanover, NH; on the Sep 21, 2016 filing they give Cambridge, MA. The address now on file (245 First Street, Cambridge, MA) is a registered-agent or shared-office address used by 7 issuers.

What this means A registered agent's address is a mailbox, not where the team works. Ask where the business actually operates.

Sources
Note · Jun 23, 2011 – Aug 10, 2026

Ben Auspitz is listed with 3 different address states: MA, CA, NH

MA on 11 filings (Jun 23, 2011 to Aug 20, 2019); CA on 3 filings (Dec 31, 2012 to Aug 10, 2026); NH on 1 filing (Jul 1, 2015).

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.

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 every filing this person is listed on (latest filing per offering, per issuer).

Same business address

14 other issuers file from the same address

A shared address can mean the same team, a shared office building or a registered agent. It is a lead, not a conclusion.

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 6 issuers 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 Ben Auspitz 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 6 issuers this person is listed on — nothing matched.
