The short version

Thomas B. Neff is listed as a director on 6 SEC Form D filings by 1 issuer between Aug 2009 and Mar 2014: KOLLTAN PHARMACEUTICALS INC (New Haven, CT — biotechnology — 2009–2014; $60M reported sold to 54 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 Arthur G. Altschul, Jr. (6 shared filings), E. Jonathan Soderstrom (6 shared filings), Joseph Schlessinger (6 shared filings), Stanley Choy (6 shared filings), Yaron Hadari (6 shared filings) and 11 others.

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

The issuer belongs to the sponsor group Overbrook (8 issuers, $662.5M reported sold, 2009–2026).

What this means A sponsor group is one team that sets up a new company for each deal. Overbrook has 8 companies on file and $662.5M reported sold in total — the group page shows the whole track record in one place.

Public records searched: federal courts (CourtListener / RECAP), SEC enforcement releases, state securities regulators (AR, AZ, CA, CT, DE, FINRA, GA, HI, ID, LA, ME, MO, MS, MT, NASAA, NC, NH, NM, OR, RI, TX, WA) — 6 bankruptcy cases matching the name listed in Key records below.

What this means 6 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 6 public filings for Thomas B. Neff and found 13 differences, 3 worth asking the sponsor about: Amount sold went down between filings; Investor count went down 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

13 differences found between the filings for Thomas B. Neff — 3 worth asking about (compared 6 filings on Oct 24, 2026)

Worth asking · Sep 8, 2009 – Jan 4, 2010

Amount sold went down between filings — KOLLTAN PHARMACEUTICALS INC

The Sep 8, 2009 filing says $3,500,000 sold; the Jan 4, 2010 Form D says $2,500,000 sold — $1,000,000 less.

What this means Amounts sold normally only go up as a raise continues. A drop can mean investors were refunded, a figure was corrected, or an earlier number was wrong. Ask the sponsor which it was.

Sources
Worth asking · Aug 12, 2009 – Sep 8, 2009

Amount sold went down between filings — KOLLTAN PHARMACEUTICALS INC

The Aug 12, 2009 filing says $40,000,000 sold; the Sep 8, 2009 Form D says $3,500,000 sold — $36,500,000 less.

What this means Amounts sold normally only go up as a raise continues. A drop can mean investors were refunded, a figure was corrected, or an earlier number was wrong. Ask the sponsor which it was.

Sources
Worth asking · Aug 12, 2009 – Sep 8, 2009

Investor count went down between filings — KOLLTAN PHARMACEUTICALS INC

The Aug 12, 2009 filing reports 54 investors; the Sep 8, 2009 Form D reports 1 investor.

What this means Investor counts normally only grow. A smaller number can mean investors left or were refunded, or a count was corrected. Ask the sponsor what happened.

Sources
Note · Aug 12, 2009

16% of the money raised went to insiders — KOLLTAN PHARMACEUTICALS INC

The Aug 12, 2009 Form D/A reports $40,000,000 sold and $6,261,900 of the proceeds used for payments to officers, directors or promoters (marked as an estimate).

What this means The filing reports how much of the money raised was paid to insiders. Over 10% is high for most deals. Ask what it paid for.

Sources
Note · Jul 24, 2008 – Sep 16, 2010

No amendment in the last 12 months on an offering that may still be open — KOLLTAN PHARMACEUTICALS INC (latest filing Sep 16, 2010)

The latest filing for this offering is dated Sep 16, 2010 (first sale Jul 24, 2008). It reports $6,000,000 sold of $7,500,000 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 · Jan 4, 2010 – Sep 16, 2010

Offering amount changed between filings — KOLLTAN PHARMACEUTICALS INC

The Jan 4, 2010 filing says $2,500,000 offered; the Sep 16, 2010 Form D/A says $7,500,000.

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 · Sep 8, 2009 – Jan 4, 2010

Offering amount lowered between filings — KOLLTAN PHARMACEUTICALS INC

The Sep 8, 2009 filing says $7,500,000 offered; the Jan 4, 2010 Form D says $2,500,000.

What this means The target raise got smaller. That can mean the plan shrank or the sponsor stopped early. Ask what changed in the deal.

Sources
Note · Aug 12, 2009 – Sep 8, 2009

Offering amount lowered between filings — KOLLTAN PHARMACEUTICALS INC

The Aug 12, 2009 filing says $40,000,000 offered; the Sep 8, 2009 Form D says $7,500,000.

What this means The target raise got smaller. That can mean the plan shrank or the sponsor stopped early. Ask what changed in the deal.

Sources
Note · Aug 12, 2009 – Jan 4, 2010

Thomas B. Neff is written 2 different ways on the filings

listed as "Thomas Neff" on 3 filings (from Aug 12, 2009), and "Thomas B. Neff" on 3 filings (from Jan 4, 2010).

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 · Aug 12, 2009 – Sep 8, 2009

Reported revenue range changed between filings — KOLLTAN PHARMACEUTICALS INC

"No Revenues" (Aug 12, 2009); then "Decline to Disclose" (Sep 8, 2009).

What this means This is the size band the issuer picks for itself on the form. A change can mean the business grew or shrank — or that it chose not to say. Ask for current numbers.

Sources
Note · Jul 27, 2012 – Dec 10, 2014

Same name, different state: "Thomas B Neff" (CA) is a separate record

This page covers filings where the address state is CT or CA. A separate record, "Thomas B Neff" with address state CA, is listed on 3 filings — most recently by FIBROGEN INC (Dec 10, 2014). Both records have filings in the same period (Jul 27, 2012 to Mar 19, 2014).

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 · May 4, 2010

Same name, different state: "Thomas Neff" (A1) is a separate record

This page covers filings where the address state is CT or CA. A separate record, "Thomas Neff" with address state A1, is listed on 1 filing — most recently by GoviEx Uranium Inc. (May 4, 2010). Both records have filings in the same period (May 4, 2010).

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 · Aug 12, 2009 – Mar 19, 2014

Thomas B. Neff is listed with 2 different address states: CA, CT

CA on 1 filing (Aug 12, 2009); CT on 5 filings (Sep 8, 2009 to Mar 19, 2014).

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.

5. Money to insiders

Registrations and other filings

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)

Property records none — individuals are not matched

Property records are matched to companies only, never to individuals, so none are matched to Thomas B. Neff by design.
