The short version

Michael Kauffman is listed as an executive officer and director on 7 SEC Form D filings by 3 issuers between Nov 2010 and Mar 2020: Karyopharm Therapeutics Inc. (Newton, MA — pharmaceuticals — 2010–2013; $165M reported sold to 33 investors), Verastem, Inc. (Needham, MA — pharmaceuticals — 2014–2020; $100M reported sold to 36 investors) and Metamark Genetics, Inc. (Cambridge, MA — biotechnology — 2012; $22.1M reported sold to 10 investors).

What this means A repeat sponsor — 3 separate companies raised money with this person listed as executive officer and director, over about 10 years. Across those companies the filings report $287.1M sold in total.

Listed alongside Mansoor Raza Mirza (4 shared filings), Alison Lawton (3 shared filings), DAN PATERSON (3 shared filings), Kenneth E. Weg (3 shared filings), Sharon Shacham (3 shared filings) and 28 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) — 19 bankruptcy cases matching the name listed in Key records below.

What this means 19 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 7 public filings for Michael Kauffman and found 9 differences: Bankruptcy case: ALL FLORIDA DELIVERY SERV. INC v. Cordo; No amendment in the last 12 months on an offering that may still be open; 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

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

Note · May 10, 2013 – Nov 27, 2013

Bankruptcy case: ALL FLORIDA DELIVERY SERV. INC v. Cordo — filed May 10, 2013

United States Bankruptcy Court, S.D. Florida. docket "ALL FLORIDA DELIVERY SERV. INC v. Cordo" filed May 10, 2013, closed Nov 27, 2013. David Cordo (listed on the same filings) is listed as Defendant ("Cordo"). 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.

Sources
Note · Apr 17, 2013 – May 1, 2013

No amendment in the last 12 months on an offering that may still be open — Karyopharm Therapeutics Inc. (latest filing May 1, 2013)

The latest filing for this offering is dated May 1, 2013 (first sale Apr 17, 2013). It reports $20,500,000 sold of $60,000,000 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.

Sources
Note · Oct 21, 2010 – Nov 5, 2010

No amendment in the last 12 months on an offering that may still be open — Karyopharm Therapeutics Inc. (latest filing Nov 5, 2010)

The latest filing for this offering is dated Nov 5, 2010 (first sale Oct 21, 2010). It reports $700,000 sold of $20,750,000 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.

Sources
Note · Nov 5, 2010 – May 1, 2013

Michael Kauffman's role changed at Karyopharm Therapeutics Inc.: director → executive officer, director

The Nov 5, 2010 filing lists Michael Kauffman as director; the May 1, 2013 Form D lists executive officer, director.

What this means Roles on Form D are self-reported by the issuer. A change can mean a real change in who runs the company, or just a different box ticked. Ask who makes decisions today.

Sources
Note · Mar 6, 2014 – Jan 7, 2020

Industry group changed between filings — Verastem, Inc.

"Biotechnology" (Mar 6, 2014); then "Pharmaceuticals" (Jan 7, 2020 to Mar 6, 2020).

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.

Sources
Note · Aug 3, 2017

Same name, different state: "Michael Kauffman" (CA) is a separate record

This page covers filings where the address state is MA. A separate record, "Michael Kauffman" with address state CA, is listed on 1 filing — most recently by Kezar Life Sciences, Inc. (Aug 3, 2017). Both records have filings in the same period (Aug 3, 2017).

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.

Sources
Note · Mar 27, 2013 – Sep 1, 2015

Same name, different state: "Michael Kauffman" (FL) is a separate record

This page covers filings where the address state is MA. A separate record, "Michael Kauffman" with address state FL, is listed on 5 filings — most recently by PocketProtein, Inc. (Sep 1, 2015). Both records have filings in the same period (Mar 27, 2013 to Sep 1, 2015).

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.

Sources
Note · Mar 6, 2014 – Jan 7, 2020

Address moved from Cambridge, MA to Needham, MA — Verastem, Inc.

The people listed on the Mar 6, 2014 filing give Cambridge, MA; on the Jan 7, 2020 filing they give Needham, MA. The address now on file (117 Kendrick Street, Suite 500, Needham, 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 · Nov 5, 2010 – May 1, 2013

Address moved from Newton, MA to Natick, MA — Karyopharm Therapeutics Inc.

The people listed on the Nov 5, 2010 filing give Newton, MA; on the May 1, 2013 filing they give Natick, MA.

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.

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).

The team behind the deals

Same business address

12 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); KY (Kentucky Secretary of State — Business Entity Search (sosbes.sos.ky.gov), searched by issuer name, data as of Oct 24, 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 3 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 Michael Kauffman 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 3 issuers this person is listed on — nothing matched.
