The short version

Peter Hirth is listed as a director on 17 SEC Form D filings by 8 issuers between Aug 2009 and Nov 2024. Largest by amount reported sold: SutroVax, Inc. (Foster City, CA — biotechnology — 2017–2020; $110M reported sold to 23 investors), Aligos Therapeutics, Inc. (South San Francisco, CA — biotechnology — 2020–2023; $105M reported sold to 38 investors), Escient Pharmaceuticals Inc (San Diego, CA — biotechnology — 2020–2022; $60M reported sold to 22 investors), KOLLTAN PHARMACEUTICALS INC (New Haven, CT — biotechnology — 2009; $60M reported sold to 54 investors), Afferent Pharmaceuticals, Inc. (San Mateo, CA — pharmaceuticals — 2015; $55M reported sold to 17 investors) and 3 more (all listed below).

What this means A repeat sponsor — 8 separate companies raised money with this person listed as director, over about 15 years. Across those companies the filings report $521.8M sold in total.

Listed alongside Kathleen Sereda Glaub (5 shared filings), Bruce Robertson (4 shared filings), Jack Nielsen (4 shared filings), Kirk Dornbush (4 shared filings), Lawrence Blatt (4 shared filings) and 74 others.

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

1 of the issuers 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 (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 17 public filings for Peter Hirth 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.

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.

CA on 16 filings (Aug 12, 2009 to Nov 26, 2024); NV on 1 filing (Mar 21, 2017).

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.

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 Peter Hirth on a Form D, newest first. A Form D is the notice a company files after it starts selling a private investment.

The team behind the deals

O
Sponsor group

Overbrook

8 issuers · 42 filings · $662.5M reported sold · 2009–2026

One team, 8 deal companies. Peter Hirth is listed on 1 of them.

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 Peter Hirth.

Same business address

20 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 Peter Hirth 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.

Public profiles and social
