The short version

Joon Lee is listed as a director on 3 SEC Form D filings by 1 issuer between Aug 2023 and Mar 2025: Inflammasome Therapeutics, Inc. (Newton, MA — biotechnology — 2023–2025; $13.2M reported sold to 62 investors).

What this means One deal on file with the SEC. A Form D is the notice a company files after it starts selling a private investment — it is a notice, not an approval.

Listed alongside Balamurali Ambati (3 shared filings), Jayakrishna Ambati (3 shared filings), Mary Weber (3 shared filings), Napoleone Ferrara (3 shared filings) and Paul Ashton (3 shared filings).

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

Public records searched: federal courts (CourtListener / RECAP), SEC enforcement releases, state securities regulators (AZ, CA, DE, TX, WA) — 1 court case matching the name, 8 bankruptcy cases matching the name listed in Key records below.

What this means 9 records came back, including 1 court case still open — open cases can take years and cost money. 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 3 public filings for Joon Lee and found 7 differences, 1 worth asking the sponsor about: Form D filed 105 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

7 differences found between the filings for Joon Lee — 1 worth asking about (compared 3 filings on Oct 24, 2026)

Worth asking · Dec 2, 2024 – Mar 17, 2025

Form D filed 105 days after the first sale — Inflammasome Therapeutics, Inc.

The filing says the first sale was Dec 2, 2024. The Form D was filed Mar 17, 2025 — 105 days later. The rule: a Form D is generally due within 15 days after the first sale, so this one is 90 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.

Sources
Note · Dec 2, 2024 – Mar 17, 2025

No amendment in the last 12 months on an offering that may still be open — Inflammasome Therapeutics, Inc. (latest filing Mar 17, 2025)

The latest filing for this offering is dated Mar 17, 2025 (first sale Dec 2, 2024). It reports $2,450,172 sold of $10,000,000 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.

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.
