The short version

Stacy Feld is listed as a director on 5 SEC Form D filings by 2 issuers between Aug 2011 and Aug 2018: T2 Biosystems, Inc. (Lexington, MA — other health care — 2011–2013; $400M reported sold to 16 investors) and ENTRINSIC HEALTH SOLUTIONS, INC. (Norwood, MA — other health care — 2017–2018; $7.5M reported sold to 7 investors).

What this means 2 separate companies raised money with this person listed as director, over about 7 years. Across those companies the filings report $407.5M sold in total.

Listed alongside Brian Fox (3 shared filings), Daniel B. Dennison (3 shared filings), Michael Warren (3 shared filings), Sadasivan Vidyasagar (3 shared filings), Stephen J. Gatto (3 shared filings) and 14 others.

What this means These are the other officers, directors or promoters the companies named on the same forms — the team around Stacy. 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) — 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 5 public filings for Stacy Feld and found 2 differences, 1 worth asking the sponsor about: Form D filed 75 days after the first sale; 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

2 differences found between the filings for Stacy Feld — 1 worth asking about (compared 5 filings on Oct 24, 2026)

Worth asking · Jun 15, 2018 – Aug 29, 2018

Form D filed 75 days after the first sale — ENTRINSIC HEALTH SOLUTIONS, INC.

The filing says the first sale was Jun 15, 2018. The Form D was filed Aug 29, 2018 — 75 days later. The rule: a Form D is generally due within 15 days after the first sale, so this one is 60 days past that.

What this means A late notice is common and carries no penalty by itself. It is worth asking the sponsor why the paperwork lagged.

Form D · Aug 29, 2018 ↗ENTRINSIC HEALTH SOLUTIONS, INC. — PartnerFacts page ↗
Sources
Note · Dec 12, 2017 – Oct 1, 2020

Same name, different state: "Stacy Feld" (CA) is a separate record

This page covers filings where the address state is MA. A separate record, "Stacy Feld" with address state CA, is listed on 5 filings — most recently by Willow Innovations, Inc. (Oct 1, 2020). Both records have filings in the same period (Dec 12, 2017 to Aug 29, 2018).

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.

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.

"Paid to sell it" = sales compensation recipients named on that filing (Item 12), each linked to FINRA BrokerCheck when a CRD number is reported.

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 2 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 Stacy Feld 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 2 issuers this person is listed on — nothing matched.
