The short version

ESILICON CORP is a corporation organized in Delaware (formed more than five years before filing), based in Sunnyvale, CA.

What this means A deal company is usually set up for one investment; its Form D is the notice it files after selling to investors.

It has filed 5 Form D filings (5 originals, 0 amendments) for 5 offerings between Oct 2010 and Aug 2012. The latest filing of each offering reports a combined $14.8M sold of $20.9M offered to 18 investors; industry as reported: other technology; latest exemption Rule 506.

What this means A repeat filer — 5 separate raises over about 2 years. Amendments are routine updates (an ongoing raise must update its Form D at least once a year).

Key people as listed: Crawford W. Beveridge (director), Eugene II A. Skulick (executive officer), Fritz Koehler (executive officer), Hao N. Nham (executive officer), John R. Harding (executive officer and director) and 25 more.

What this means These are the people the company itself named as running or promoting it. Tap a name to see every other deal they are on.

No sales commissions, finder's fees or proceeds to insiders are reported. No sales-compensation recipients are listed.

What this means No broker was paid — the sponsor sold it directly to investors.

Activity: 0 new offerings in the last 12 months; no amendment on file; latest filing Aug 24, 2012.

What this means No new raise filed in the past year — this deal company may be done raising, or simply quiet.

Searched SEC Form ADV bulk data (registered + exempt reporting advisers) (24,962 records as of Oct 2, 2026, 8:00 AM ET) — nothing matched ESILICON CORP.

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), property records (NYC, FL, IL and TX counties) — 1 court case matching the name, 1 bankruptcy case matching the name listed in Key records below.

What this means 2 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 5 public filings for ESILICON CORP and found 6 differences, 1 worth asking the sponsor about: 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.

No public statement by this issuer has been collected yet, so there is nothing to compare. Sources compared: the sponsor's own website (known from the issuer's own filings — Form C issuer website, EDGAR company profile — an approved profile claim or Form ADV Item 1.I of its matched adviser) · SEC Form D · SEC Form ADV (IAPD) · Internet Archive · No website is on file for this issuer yet.

6 differences found between the filings for ESILICON CORP — 1 worth asking about (compared 5 filings on Oct 24, 2026)

Note · Aug 8, 2003 – Nov 10, 2003

Bankruptcy case: Hoang Yen Dang and Nham Van Le — filed Aug 8, 2003

United States Bankruptcy Court, N.D. California docket "Hoang Yen Dang and Nham Van Le" filed Aug 8, 2003, closed Nov 10, 2003. Hao N. Nham (listed on the same filings) is listed as Debtor ("Hoang Yen Dang and Nham Van Le"). Our match estimate: 70%.

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.

No amendment in the last 12 months on an offering that may still be open — ESILICON CORP (latest filing Oct 22, 2010)

The latest filing for this offering is dated Oct 22, 2010 (first sale Dec 23, 2009). It reports $3,879,491 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.

Executive officers, directors and promoters as self-reported by the issuer, one row per person. Spellings of the same name (same first and last name, or the same full name that EDGAR split differently into middle and last name) with no conflicting middle initial are shown on one row (none on this issuer); dates and counts come from the filings that list each name. Licensed persons: FINRA BrokerCheck ↗ · SEC IAPD ↗. Middle names: the SEC Form D data set (RELATEDPERSONS.tsv) repeats the previous person's middle name into later rows of the same filing; where that happened PartnerFacts shows the name without the repeated middle name and keeps the data-set spelling on record (R. David D. Spreng; Robert D. Selvi; Timothy F. Chen; W. Blake F. Winchell) — the filing on EDGAR is the source.
