The short version

Yi Sun is listed as an executive officer, director, and promoter on 21 SEC Form D filings by 17 issuers between May 2009 and Sep 2026. Largest by amount reported sold: HORSLEY BRIDGE INTERNATIONAL V LP (San Francisco, CA — pooled investment fund — 2009; $1.54B reported sold to 45 investors), HORSLEY BRIDGE VENTURE 15, L.P. (San Francisco, CA — pooled investment fund — 2023; $1.45B reported sold), Horsley Bridge XI Venture, L.P. (San Francisco, CA — pooled investment fund — 2015; $1.1B reported sold to 63 investors), Horsley Bridge XI Growth Buyout, L.P. (San Francisco, CA — pooled investment fund — 2016; $281M reported sold to 47 investors), Horsley Bridge X Growth Buyout, L.P. (San Francisco, CA — pooled investment fund — 2013–2014; $185.2M reported sold to 26 investors) and 12 more (all listed below).

What this means That is a lot of deals — 17 separate companies raised money with this person listed as executive officer, director, and promoter, over about 17 years. Across those companies the filings report $4.56B sold in total.

Listed alongside Joshua D. Freeman (21 shared filings), Kathleen M. Murphy (21 shared filings), Lance Cottrill (21 shared filings), Clara Vu (20 shared filings), Du Chai (20 shared filings) and 37 others.

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

All 17 issuers belong to the sponsor group Horsley Bridge (17 issuers, $3.11B reported sold, 2009–2026).

What this means A sponsor group is one team that sets up a new company for each deal. Horsley Bridge has 17 companies on file and $3.11B 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) — 1 bankruptcy case matching the name listed in Key records below.

What this means 1 record 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 21 public filings for Yi Sun and found 11 differences, 3 worth asking the sponsor about: Amount sold went down between filings; Yi Sun appears on 10 deals that stopped filing before reaching their target; 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

11 differences found between the filings for Yi Sun — 3 worth asking about (compared 21 filings on Oct 24, 2026)

Bankruptcy case: Jon D Roller and Nellie E Roller — filed Sep 12, 2012

United States Bankruptcy Court, C.D. California docket "Jon D Roller and Nellie E Roller" filed Sep 12, 2012, closed Mar 19, 2013. Jon Roller (listed on the same filings) is listed as Debtor ("Jon D Roller and Nellie E Roller"). 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.

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.

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 17

Every issuer that named Yi Sun 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

HB
Sponsor group

Horsley Bridge

17 issuers · 21 filings · $3.11B reported sold · 2009–2026

One team, 17 deal companies. Yi Sun is listed on 17 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 Yi Sun.

Same business address

37 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).
