The short version

Timothy Springer is listed as a director on 16 SEC Form D filings by 7 issuers between Jan 2016 and Feb 2025. Largest by amount reported sold: Tectonic Therapeutic, Inc. (Watertown, MA — biotechnology — 2025; $185M reported sold to 29 investors), Seismic Therapeutic, Inc. (Watertown, MA — industry reported as "Other" — 2023–2024; $146.3M reported sold to 38 investors), Cartesian Therapeutics, Inc.

(Watertown, MA — biotechnology — 2021; $80.1M reported sold to 23 investors) and 2 more (all listed below).

What this means A repeat sponsor — 7 separate companies raised money with this person listed as director, over about 9 years. Across those companies the filings report $724.7M sold in total.

Listed alongside Amir Nashat (8 shared filings), Timothy Barabe (7 shared filings), Aymeric Sallin (6 shared filings), Patrick Zenner (6 shared filings), Carsten Brunn (5 shared filings) and 73 others.

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

The issuers belong to 2 sponsor groups: Tectonic Therapeutic (2 issuers, $265.1M reported sold, 2016–2025) and Scholar Rock (2 issuers, $83.3M reported sold, 2016–2018).

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 (AK, AL, AR, AZ, CA, CT, DE, FINRA, GA, HI, ID, IL, KS, KY, LA, MA, MD, ME, MI, MO, MS, MT, NASAA, NC, ND, NH, NM, NV, OK, OR, PA, RI, SC, SD, TN, TX, VT, WA, WI, WV, WY) — 9 bankruptcy cases matching the name listed in Key records below.

What this means 9 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 16 public filings for Timothy Springer and found 10 differences: Bankruptcy case: David Siewers; 4 Form Ds were filed more than 15 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

10 differences found between the filings for Timothy Springer (compared 16 filings on Oct 24, 2026)

Note · Jan 26, 1990 – Aug 18, 1992

Bankruptcy case: David Siewers — filed Jan 26, 1990

United States Bankruptcy Court, D. Massachusetts docket "David Siewers" filed Jan 26, 1990, closed Aug 18, 1992. David Siewers (listed on the same filings) is listed as Debtor ("David Siewers"). Our match estimate: 65%.

What this means A bankruptcy filing was found. Many are old or personal and have nothing to do with the deal — but ask what it was and when it closed.

Sources
Note · Dec 17, 2015 – Dec 4, 2023

4 Form Ds were filed more than 15 days after the first sale

Form D filed 17 days after the first sale — Seismic Therapeutic, Inc. · Form D filed 18 days after the first sale — Cartesian Therapeutics, Inc. · Form D filed 17 days after the first sale — Scholar Rock Holding Corp · Form D filed 18 days after the first sale — Scholar Rock LLC

What this means Late notices are common and carry no penalty by themselves. A pattern of late paperwork is worth asking the sponsor about.

Sources
Note · Dec 17, 2015 – Mar 1, 2023

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 — Morphic Holding, Inc. (latest filing Mar 1, 2023) · No amendment in the last 12 months on an offering that may still be open — Scholar Rock Holding Corp (latest filing Jan 8, 2018) · No amendment in the last 12 months on an offering that may still be open — Morphic Holding, Inc. (latest filing Jul 13, 2016) · No amendment in the last 12 months on an offering that may still be open — Scholar Rock LLC (latest filing Jan 4, 2016)

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 · Dec 4, 2023 – Sep 12, 2024

Offering amount changed between filings — Seismic Therapeutic, Inc.

The Dec 4, 2023 filing says $121,279,929 offered; the Sep 12, 2024 Form D/A says $146,279,914.

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 · Jan 4, 2016 – Apr 15, 2021

Timothy Springer is written 2 different ways on the filings

listed as "Timothy Springer" on 11 filings (from Jan 4, 2016), and "Timothy A. Springer" on 5 filings (from Apr 15, 2021).

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 7, 2021 – Oct 7, 2022

Same name, different state: "Timothy S. Springer" (TX) is a separate record

This page covers filings where the address state is MA or MD. A separate record, "Timothy S. Springer" with address state TX, is listed on 3 filings — most recently by Move It Opportunities Fund II, LP (Oct 7, 2022). Both records have filings in the same period (Apr 7, 2021 to Oct 7, 2022).

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 3, 2017

Same name, different state: "Timothy Springer" (VA) is a separate record

This page covers filings where the address state is MA or MD. A separate record, "Timothy Springer" with address state VA, is listed on 1 filing — most recently by Level Access Holdings, Inc. (May 3, 2017). Both records have filings in the same period (May 3, 2017).

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 · Dec 4, 2023 – Sep 12, 2024

Address moved from Cambridge, MA to Watertown, MA — Seismic Therapeutic, Inc.

The people listed on the Dec 4, 2023 filing give Cambridge, MA; on the Sep 12, 2024 filing they give Watertown, MA.

What this means Businesses move; this just shows the two places and dates. If you were told one city and the forms say another, ask which is current.

Sources
Note · Aug 18, 2020 – Dec 1, 2023

Address moved from Watertown, MA to Gaithersburg, MD — Cartesian Therapeutics, Inc.

The people listed on the Aug 18, 2020 filing give Watertown, MA; on the Dec 1, 2023 filing they give Gaithersburg, MD. The address now on file (704 Quince Orchard Rd, Gaithersburg, MD) is a registered-agent or shared-office address used by 9 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 · Jan 4, 2016 – Feb 14, 2025

Timothy Springer is listed with 2 different address states: MA, MD

MA on 14 filings (Jan 4, 2016 to Feb 14, 2025); MD on 2 filings (Dec 4, 2023 to Jul 17, 2024).

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

4 of 15 offerings report sales commissions totalling $22,911,639; 0 report finder's fees; 2 report proceeds to related persons totalling $3,750,000. (includes amounts the issuer reported as estimates)

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).
