The short version

Kenneth E. Weg is listed as an executive officer and director on 8 SEC Form D filings by 3 issuers between Apr 2009 and Aug 2013: Karyopharm Therapeutics Inc. (Newton, MA — pharmaceuticals — 2013; $165M reported sold to 33 investors), AVEO PHARMACEUTICALS INC (Cambridge, MA — pharmaceuticals — 2009–2011; $60.8M reported sold to 21 investors) and Metamark Genetics, Inc. (Cambridge, MA — biotechnology — 2009–2012; $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 4 years. Across those companies the filings report $247.9M sold in total.

Listed alongside Raju Kucherlapati (6 shared filings), Anthony Evnin (3 shared filings), Douglas Cole (3 shared filings), Mansoor Raza Mirza (3 shared filings), Michael Kauffman (3 shared filings) and 25 others.

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

Public records searched: federal courts (CourtListener / RECAP), SEC enforcement releases, state securities regulators (AZ, CA, DE, TX, WA) — 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 8 public filings for Kenneth E. Weg and found 7 differences: Kenneth E. Weg's role changed at Metamark Genetics, Inc.: executive officer, director → director; 4 offerings have no amendment in the last 12 months and 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

7 differences found between the filings for Kenneth E. Weg (compared 8 filings on Oct 24, 2026)

Note · Jul 9, 2010 – Nov 15, 2012

Kenneth E. Weg's role changed at Metamark Genetics, Inc.: executive officer, director → director

The Jul 9, 2010 filing lists Kenneth E. Weg as executive officer, director; the Nov 15, 2012 Form D lists 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 18, 2009 – May 1, 2013

4 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 — Karyopharm Therapeutics Inc. (latest filing May 1, 2013) · No amendment in the last 12 months on an offering that may still be open — Metamark Genetics, Inc. (latest filing Jul 9, 2010) · No amendment in the last 12 months on an offering that may still be open — Metamark Genetics, Inc. (latest filing May 8, 2009) · No amendment in the last 12 months on an offering that may still be open — AVEO PHARMACEUTICALS INC (latest filing Apr 1, 2009)

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
Note · Apr 1, 2009 – May 8, 2009

Kenneth E. Weg is written 2 different ways on the filings

listed as "Kenneth Weg" on 3 filings (from Apr 1, 2009), and "Kenneth E. Weg" on 5 filings (from May 8, 2009).

What this means Same person, written differently — a middle name or suffix left off, or spelled another way. It is normal, but check that the full legal name matches your subscription documents.

Sources
Note · Apr 1, 2009 – Nov 3, 2010

Industry group changed between filings — AVEO PHARMACEUTICALS INC

"Other" (Apr 1, 2009); then "Pharmaceuticals" (Nov 3, 2010 to May 31, 2011).

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 · Jul 9, 2010 – Nov 15, 2012

Address moved from Naples, FL to Cambridge, MA — Metamark Genetics, Inc.

The people listed on the Jul 9, 2010 filing give Naples, FL; on the Nov 15, 2012 filing they give Cambridge, MA. The address now on file (245 First Street, Suite 150, 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 · May 8, 2009 – Jul 9, 2010

Address moved from Princeton, NJ to Naples, FL — Metamark Genetics, Inc.

The people listed on the May 8, 2009 filing give Princeton, NJ; on the Jul 9, 2010 filing they give Naples, FL. The address now on file (245 First Street, Suite 150, 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 · Apr 1, 2009 – Aug 1, 2013

Kenneth E. Weg is listed with 3 different address states: MA, NJ, FL

MA on 6 filings (Apr 1, 2009 to Aug 1, 2013); NJ on 1 filing (May 8, 2009); FL on 1 filing (Jul 9, 2010).

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).

Property records none — individuals are not matched
