The short version

William Weldon is listed as a director on 7 SEC Form D filings by 2 issuers between Feb 2015 and Apr 2025: HeartFlow Holding, Inc. (Mountain View, CA — other health care — 2023–2025; $215.9M reported sold to 79 investors) and Heartflow, Inc. (Redwood City, CA — biotechnology — 2015–2019; $104.7M reported sold to 29 investors).

What this means 2 separate companies raised money with this person listed as director, over about 10 years. Across those companies the filings report $320.6M sold in total.

Listed alongside Casey Tansey (7 shared filings), Charles A. Taylor (7 shared filings), Jeff Lightcap (7 shared filings), Lonnie Smith (7 shared filings), H. Baird Radford, III (4 shared filings) and 17 others.

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

All 2 issuers belong to the sponsor group Heartflow (2 issuers, $115M reported sold, 2009–2025).

What this means A sponsor group is one team that sets up a new company for each deal. Heartflow has 2 companies on file and $115M 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) — 24 bankruptcy cases matching the name listed in Key records below.

What this means 24 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 7 public filings for William Weldon and found 7 differences: Bankruptcy case: Bank One Delaware v. Barabe; Form D filed 16 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 William Weldon (compared 7 filings on Oct 24, 2026)

Note · Mar 1, 2004 – Apr 30, 2004

Bankruptcy case: Bank One Delaware v. Barabe — filed Mar 1, 2004

United States Bankruptcy Court, C.D. California docket "Bank One Delaware v. Barabe" filed Mar 1, 2004, closed Apr 30, 2004. Tim Barabe (listed on the same filings) is listed as Defendant ("Barabe"). 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.

Sources
Note · Mar 26, 2025 – Apr 11, 2025

Form D filed 16 days after the first sale — HeartFlow Holding, Inc.

The filing says the first sale was Mar 26, 2025. The Form D was filed Apr 11, 2025 — 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.

Sources
Note · Mar 2, 2023 – Apr 24, 2023

Form D filed 53 days after the first sale — HeartFlow Holding, Inc.

The filing says the first sale was Mar 2, 2023. The Form D was filed Apr 24, 2023 — 53 days later. The rule: a Form D is generally due within 15 days after the first sale, so this one is 38 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.

4 offerings have no amendment in the last 12 months and may still be open

No amendment in the last 12 months on an offering that may still be open — HeartFlow Holding, Inc. (latest filing Feb 7, 2025) · No amendment in the last 12 months on an offering that may still be open — Heartflow, Inc. (latest filing Jun 14, 2019) · No amendment in the last 12 months on an offering that may still be open — Heartflow, Inc. (latest filing Dec 4, 2017) · No amendment in the last 12 months on an offering that may still be open — Heartflow, Inc. (latest filing May 20, 2016)

What this means SEC rules expect a yearly amendment while an offering is still going. Ask the sponsor which of these raises have closed.

Sources
Note · Feb 12, 2015 – May 20, 2016

Offering amount changed between filings — Heartflow, Inc.

The Feb 12, 2015 filing says $46,268,662 offered; the May 20, 2016 Form D/A says $110,881,528.

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 · Mar 15, 2021 – Oct 11, 2022

Same name, different state: "William Weldon" (OR) is a separate record

This page covers filings where the address state is CA. A separate record, "William Weldon" with address state OR, is listed on 2 filings — most recently by Prolifiq Software Inc (Oct 11, 2022). Both records have filings in the same period (Mar 15, 2021 to Oct 11, 2022).

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.

Same name, different state: "William C. Weldon" (IN) is a separate record

This page covers filings where the address state is CA. A separate record, "William C. Weldon" with address state IN, is listed on 3 filings — most recently by Axiota Animal Health, Inc. (Jan 20, 2021). Both records have filings in the same period (Dec 17, 2019 to Jan 20, 2021).

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.

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 2

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).

Adviser registration (Form ADV)

None of the 2 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.

Other offering types (Regulation A and Regulation Crowdfunding)

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 none — individuals are not matched

Property records are matched to companies only, never to individuals, so none are matched to William Weldon 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 2 issuers this person is listed on — nothing matched.
