The short version

TAN LU is listed as an executive officer and director on 9 SEC Form D filings by 1 issuer between Mar 2022 and Jul 2025: EUCLID LABS, INC. (San Francisco, CA — other technology — 2022–2025; $129.4M reported sold to 107 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 ZHUOXUN YIN (9 shared filings), SIDA ZHANG (8 shared filings), ZHUOJIE ZHOU (7 shared filings), Ailin Pallisso Poux (1 shared filing), Daniel Burstein (1 shared filing) and 3 others.

What this means These are the other officers, directors or promoters the companies named on the same forms — the team around TAN. 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) — 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 9 public filings for TAN LU and found 10 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.

4. Differences between public sources

Comparisons cover issuers and sponsor groups — see the issuer pages under Deals

10 differences found between the filings for TAN LU — 3 worth asking about (compared 9 filings on Oct 24, 2026)

Worth asking · Jan 25, 2023 – Feb 3, 2023

Amount sold went down between filings — EUCLID LABS, INC.

The Jan 25, 2023 filing says $16,859,571 sold; the Feb 3, 2023 Form D/A says $16,233,546 sold — $626,025 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.

Sources
Worth asking · Jan 25, 2023 – Feb 3, 2023

Investor count went down between filings — EUCLID LABS, INC.

The Jan 25, 2023 filing reports 31 investors; the Feb 3, 2023 Form D/A reports 26 investors.

What this means Investor counts normally only grow. A smaller number can mean investors left or were refunded, or a count was corrected. Ask the sponsor what happened.

Sources
Worth asking · Mar 10, 2022 – Dec 30, 2022

Form D filed 295 days after the first sale — EUCLID LABS, INC.

The filing says the first sale was Mar 10, 2022. The Form D was filed Dec 30, 2022 — 295 days later. The rule: a Form D is generally due within 15 days after the first sale, so this one is 280 days past that.

What this means The notice went in months after money was taken in. Late notices are common and carry no penalty by themselves, but it is fair to ask the sponsor why the paperwork lagged.

Sources
Note · May 27, 2025 – Jul 10, 2025

Form D filed 44 days after the first sale — EUCLID LABS, INC.

The filing says the first sale was May 27, 2025. The Form D was filed Jul 10, 2025 — 44 days later. The rule: a Form D is generally due within 15 days after the first sale, so this one is 29 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 · Feb 3, 2023 – Jun 26, 2023

TAN LU's role changed at EUCLID LABS, INC.: executive officer, director → director

The Feb 3, 2023 filing lists TAN LU as executive officer, director; the Jun 26, 2023 Form D lists director.

What this means Roles on Form D are self-reported by the issuer. A change can mean a real change in who runs the company, or just a different box ticked. Ask who makes decisions today.

Sources
Note · Jan 25, 2023 – Feb 3, 2023

Offering amount lowered between filings — EUCLID LABS, INC.

The Jan 25, 2023 filing says $16,859,571 offered; the Feb 3, 2023 Form D/A says $16,233,546.

What this means The target raise got smaller. That can mean the plan shrank or the sponsor stopped early. Ask what changed in the deal.

Sources
Note · Mar 23, 2022 – Feb 3, 2023

Offering amount changed between filings — EUCLID LABS, INC.

The Mar 23, 2022 filing says $26,997,704 offered; the Feb 3, 2023 Form D/A says $27,623,729.

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 · Dec 30, 2022 – Jan 25, 2023

Offering amount changed between filings — EUCLID LABS, INC.

The Dec 30, 2022 filing says $7,060,465 offered; the Jan 25, 2023 Form D/A says $16,859,571.

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 · Jun 14, 2022 – Jun 29, 2022

No amendment in the last 12 months on an offering that may still be open — EUCLID LABS, INC. (latest filing Jun 29, 2022)

The latest filing for this offering is dated Jun 29, 2022 (first sale Jun 14, 2022). It reports $129,399,971 sold of $129,999,964 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.

Sources
Note · Mar 28, 2025 – Jun 13, 2025

Same name, different state: "Tan Lu" (E9) is a separate record

This page covers filings where the address state is CA. A separate record, "Tan Lu" with address state E9, is listed on 2 filings — most recently by Keiko Inc. (Jun 13, 2025). Both records have filings in the same period (Mar 28, 2025 to Jun 13, 2025).

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
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.
