The short version

Brian E. Chee is listed as an executive officer and director on 12 SEC Form D filings by 8 issuers between Jun 2014 and Oct 2026. Largest by amount reported sold: Polaris Partners VII, L.P. (Waltham, MA — pooled investment fund — 2014–2015; $435.6M reported sold to 43 investors), Polaris Partners X, L.P. (Boston, MA — pooled investment fund — 2022–2023; $354.6M reported sold to 92 investors), Polaris Partners XI, L.P. (Boston, MA — pooled investment fund — 2025–2026; $187.2M reported sold to 24 investors), Polaris Entrepreneurs' Fund VII, L.P. (Waltham, MA — pooled investment fund — 2014; $26M reported sold to 33 investors), Polaris Entrepreneurs' Fund VIII, L.P. (Boston, MA — pooled investment fund — 2017; $14.5M reported sold to 34 investors) and 3 more (all listed below).

What this means A repeat sponsor — 8 separate companies raised money with this person listed as executive officer and director, over about 12 years. Across those companies the filings report $1.02B sold in total.

Listed alongside Amir Nashat (8 shared filings), David G. Barrett (7 shared filings), Amy Schulman (6 shared filings), Bryce Youngren (6 shared filings), Jonathan Flint (4 shared filings) and 9 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.

All 8 issuers belong to the sponsor group Polaris (12 issuers, $2.15B reported sold, 2010–2026).

What this means A sponsor group is one team that sets up a new company for each deal. Polaris has 12 companies on file and $2.15B 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 (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) — 2 bankruptcy cases matching the name listed in Key records below.

What this means 2 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 12 public filings for Brian E. Chee and found 11 differences, 2 worth asking the sponsor about: Brian E. Chee appears on 3 deals that stopped filing before reaching their target; Paid seller listed without a CRD number: Polaris Investments AG; 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

11 differences found between the filings for Brian E. Chee — 2 worth asking about (compared 12 filings on Oct 24, 2026)

Worth asking · Jul 12, 2016 – Jun 24, 2020

Brian E. Chee appears on 3 deals that stopped filing before reaching their target

Polaris Healthcare Technology Opportunities Fund, L.P. (last filing Jun 24, 2020; $0 sold of $100,000,000); Polaris Partners IX, L.P. (last filing Jun 17, 2019; $0 sold of $400,000,000); Polaris Partners VIII, L.P. (last filing Jul 12, 2016; $0 sold of $400,000,000). Each has no filing in more than two years and reported under half its target sold.

What this means An issuer whose last filing is more than two years old and reported under half its target sold. The raise may have closed early or quietly stopped. Ask what happened to each.

Paid seller listed without a CRD number: Polaris Investments AG — Polaris Partners XI, L.P.

Polaris Investments AG is listed as receiving sales compensation on 2 filings (Oct 21, 2025 to Oct 20, 2026) with no FINRA CRD number given.

What this means People paid to sell securities normally hold a FINRA registration with a CRD number. Without one we cannot look them up on BrokerCheck. Ask who they are and whether they are registered.

No amendment in the last 12 months on an offering that may still be open — Polaris Partners X, L.P. (latest filing Apr 21, 2023)

The latest filing for this offering is dated Apr 21, 2023 (first sale Feb 11, 2022). It reports $354,590,909 sold of $355,000,000 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.

The Feb 10, 2022 filing says $400,000,000 offered; the Apr 21, 2023 Form D/A says $355,000,000.

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.

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.

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 8

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

Sources

Issuers are grouped when their Form D filings share related persons, a management entity or a business address (automatic match from the filings). "Listed" marks the issuers that name Brian E. Chee.

Same business address

40 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 8 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 Brian E. Chee 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 8 issuers this person is listed on — nothing matched.
