Listed alongside Amar Sawhney (2 shared filings), Andrew Hack (2 shared filings), Bjarne Bergheim (2 shared filings), Daniel Davis (2 shared filings), Daniel Even (2 shared filings) and 34 others.
What this means These are the other officers, directors or promoters the companies named on the same forms — the team around Fan. Each name links to their own page.
The issuers belong to 2 sponsor groups: Imperative (2 issuers, $117.2M reported sold, 2016–2026) and Group linked by Olav B. Bergheim (14 issuers, $144.9M reported sold, 2008–2025).
What this means This person is listed across more than one sponsor team; each group page shows that team's full track record.
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) — 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 7 public filings for Fan Yu and found 8 differences: Bankruptcy case: Onramp Funds, Inc v. Khosravi; Bankruptcy case: FIA Card Services, N.A. v. Khosravi-Sereshki; 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.

8 differences found between the filings for Fan Yu (compared 7 filings on Oct 24, 2026)
United States Bankruptcy Court, C.D. California docket "Onramp Funds, Inc v. Khosravi" filed Sep 12, 2025 (Open). Farhad Khosravi (listed on the same filings) is listed as Defendant ("Khosravi"). 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.
United States Bankruptcy Court, N.D. California docket "FIA Card Services, N.A. v. Khosravi-Sereshki" filed Nov 30, 2009, closed Feb 11, 2010. Farhad Khosravi (listed on the same filings) is listed as Defendant ("Khosravi-Sereshki"). 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.
The filing says the first sale was Jul 26, 2021. The Form D was filed Aug 11, 2021 — 16 days later. The rule: a Form D is generally due within 15 days after the first sale, so this one is 1 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.

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.

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.

A shared address can mean the same team, a shared office building or a registered agent. It is a lead, not a conclusion.
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); KY (Kentucky Secretary of State — Business Entity Search (sosbes.sos.ky.gov), searched by issuer name, data as of Oct 24, 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.

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).
None of the 4 issuers this person is listed on appears in Form ADV (searched 24,962 advisers as of Oct 2, 2026). A person is never an adviser firm; Form ADV is checked for the issuers and the management companies they are listed with.
Searched SEC Regulation A Data Sets (Forms 1-A, 1-K, 1-Z; 2015 Q2 → 2026 Q3); SEC Crowdfunding Offerings Data Sets (Form C family; 2016 Q2 → 2026 Q3); EDGAR form index for 2026 Q3 → 2026 Q4 (51,358 records as of Oct 23, 2026, 8:41 PM ET) — nothing matched this name.
Property records are matched to companies only, never to individuals, so none are matched to Fan Yu by design. Searched property records in Hillsborough County FL (Clerk recorded-document index Oct 14, 2026 to Oct 15, 2026 + FL DOR 2026 ownership roll), Miami-Dade County FL (FL DOR 2026 ownership roll), Harris County TX (HCAD 2026 ownership roll), Dallas County TX (DCAD 2026 ownership roll), New York City ACRIS documents and PLUTO ownership rows already retrieved for other issuers, Cook County IL sale and ownership rows already retrieved for other issuers (814,874 records as of Oct 23, 2026, 8:59 PM ET) for the 4 issuers this person is listed on — nothing matched.
