Generated from EDGAR primary sources

Thetis Pharmaceuticals LLC, a Connecticut-based pharmaceutical operating company, filed a Form D on 2026-10-13 for a Rule 506(b) private offering of debt securities with an option to acquire equity, reporting $560,000 raised from 10 investors. No minimum investment amount or first sale date is disclosed on the filing. This is an original (non-amendment) filing and does not appear to be part of a known investment platform or fund sponsor group.

This filing reflects a small private debt/convertible-type financing by an operating pharmaceutical issuer rather than a pooled investment fund; the $560K total raise and 10-investor count represent a modest bridge-financing round, well below the scale typical of institutional alternative-investment vehicles filing under 506(b).

Data Flags

First Sale DateNo first sale date disclosed on a sub-$100M offering; combined with the absence of a stated minimum investment, this is consistent with an early-stage or in-progress raise rather than a completed closing.
Industry GroupIndustry Group field is not specified despite the issuer being identifiably a pharmaceutical company, limiting automated categorization.

Grouped from Form D issuer names (generation, sleeve, jurisdiction and legal-form tokens removed); a name-only match, so abbreviated or renamed vehicles can be missed. Sold and investor figures are each vehicle's latest Form D; sleeves that report the same figure share one family-wide total and are counted once. Performance lines are what a public pension plan reports for its own interest in that fund, net, on the plan's cash flows and valuation date; they are not the general partner's figures.

Questions About Thetis Pharmaceuticals LLC

Each answer is built from the values on the SEC filing and the AltStreet ledger, not from the issuer's marketing.

What is Thetis Pharmaceuticals LLC?

Thetis Pharmaceuticals LLC is a Connecticut limited liability company that filed a Form D with the SEC on October 13, 2026 in the Pharmaceuticals industry group. The filing claims Rule 506(b) for an offering of debt.

Is Thetis Pharmaceuticals LLC legit?

AltStreet does not rate legitimacy; it reports the public record. Thetis Pharmaceuticals LLC filed a Form D with the SEC on October 13, 2026 claiming Rule 506(b). A Form D is a notice of an exempt offering, not a review or approval of it. The newest notice reports $560,300 sold to 10 investors. AltStreet's enforcement record (SEC, FINRA and state actions) shows no action naming the issuer as of today. Before investing, confirm the filing on EDGAR, check the seller's registration on FINRA BrokerCheck, and read the offering documents, which a Form D does not include.

Is Thetis Pharmaceuticals LLC registered with or approved by the SEC?

No. A Form D is a notice that an issuer is selling securities under an exemption from registration, and the SEC does not review, approve, or pass on the merits of the offering. The filing shows that Thetis Pharmaceuticals LLC claimed Rule 506(b) and disclosed the items the form requires, such as the amount sold, the minimum investment, related persons, and anyone paid to sell the securities. It does not verify the issuer's claims or its business.

How much has Thetis Pharmaceuticals LLC raised?

Thetis Pharmaceuticals LLC reported $560,300 sold from 10 investors of a $1,000,000 total offering as of the Form D filed October 13, 2026.

Who can invest in Thetis Pharmaceuticals LLC?

The offering relies on Rule 506(b), which permits sales to accredited investors and to no more than 35 non-accredited investors who meet a sophistication standard, and prohibits general solicitation. The filing reports no non-accredited investors. The filing lists the minimum investment as $0, meaning no minimum was stated.

What is the minimum investment in Thetis Pharmaceuticals LLC?

The Form D lists the minimum investment as $0, which means the issuer did not state a minimum on the form. The offering documents, not the Form D, set the actual subscription terms.

Who is selling Thetis Pharmaceuticals LLC and how are they paid?

The Form D names no recipient of sales compensation, which usually means the issuer or its affiliates are placing the securities directly. Sales commissions are reported as $0 and finders' fees as $0. Form D allows these to be estimates.

Who is behind Thetis Pharmaceuticals LLC?

The Form D lists 6 related persons: Gary Mathias, executive officer, director (Manager); Walter Ogier, director (Manager); Frank C. Sciavolino, director (Manager); Dennis Willson, director (Manager); Fabio Cataldi, director (Manager); David Cook, director (Manager). Form D Item 3 requires executive officers, directors, and promoters of the issuer to be listed.

Where is Thetis Pharmaceuticals LLC located?

The issuer's address on its SEC filings is 80 Meadows Road, Deep River, CT 06417. Its phone number of record is 203-470-7772. It is organized under the laws of Connecticut.

How long is the Thetis Pharmaceuticals LLC offering open?

The issuer indicated that the offering is not intended to last more than one year. An issuer must amend its Form D annually while a continuing offering stays open; 1 amendment is on record for this CIK.

What is Thetis Pharmaceuticals LLC's revenue?

The issuer declined to disclose its revenue range on the Form D, which the form permits.
