The short version

Brian Halak is listed as an executive officer and director on 41 SEC Form D filings by 18 issuers between May 2009 and Jun 2026. Largest by amount reported sold: Domain Partners VIII, L.P. (Princeton, NJ — pooled investment fund — 2009; $371.1M reported sold to 32 investors), Domain Partners IX, L.P. (Princeton, NJ — pooled investment fund — 2014–2016; $163.6M reported sold to 6 investors), SonoThera, Inc. (South San Francisco, CA — biotechnology — 2022–2026; $125.5M reported sold to 22 investors), ALIMERA SCIENCES INC (Alpharetta, GA — pharmaceuticals — 2009–2021; $81M reported sold to 25 investors), Bionano Genomics, Inc. (San Diego, CA — biotechnology — 2011–2015; $68.4M reported sold to 27 investors) and 13 more (all listed below).

What this means That is a lot of deals — 18 separate companies raised money with this person listed as executive officer and director, over about 17 years. Across those companies the filings report $997.4M sold in total.

Listed alongside Michael Gertner (9 shared filings), Mark Brooks (8 shared filings), Peter Cohn (8 shared filings), Brian H. Dovey (6 shared filings), David Barker (6 shared filings) and 110 others.

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

The issuers belong to 3 sponsor groups: Domain (3 issuers, $538.4M reported sold, 2009–2016), Carticept (2 issuers, $16.6M reported sold, 2010–2016) and Gi Dynamics (3 issuers, $2.58M reported sold, 2010–2023).

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 (AR, AZ, CA, CT, DE, FINRA, GA, HI, ID, LA, ME, MO, MS, MT, NASAA, NC, NH, NM, OR, RI, 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 41 public filings for Brian Halak and found 18 differences, 3 worth asking the sponsor about: 34% of the money raised went to insiders; Brian Halak appears on 3 deals that stopped filing before reaching their target; 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.

listed as "Brian Halak" on 32 filings (from May 27, 2009), and "Brian K. Halak" on 9 filings (from Jun 10, 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.

Industry group changed between filings — Bionano Genomics, Inc.

"Biotechnology" (Mar 24, 2011); then "Pharmaceuticals" (Jul 5, 2012 to Jan 27, 2015).

Same name, different state: "Brian K. Halak" (MA) is a separate record

This page covers filings where the address state is PA or NJ or CA or MD or GA or WA. A separate record, "Brian K. Halak" with address state MA, is listed on 1 filing — most recently by Dicerna Pharmaceuticals Inc (Aug 15, 2013). Both records have filings in the same period (Aug 15, 2013).

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.

NJ on 15 filings (May 27, 2009 to Dec 7, 2016); CA on 15 filings (Jul 22, 2009 to Jun 30, 2026); MD on 3 filings (Jun 24, 2010 to Jun 15, 2018); PA on 2 filings (Mar 24, 2011 to Oct 8, 2025); GA on 5 filings (May 25, 2011 to Apr 27, 2021); WA on 1 filing (Sep 2, 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.

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

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).

Deals 18

Every issuer that named Brian Halak on a Form D, newest first. A Form D is the notice a company files after it starts selling a private investment.
