Public records searched: federal courts (CourtListener / RECAP), SEC enforcement releases, state securities regulators (AZ, CA, DE, TX, WA) — 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 6 differences: Form D filed 16 days after the first sale; Form D filed 53 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

6 differences found between the filings for William Weldon (compared 7 filings on Oct 24, 2026)

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.

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.

Note · Jan 30, 2015 – Feb 7, 2025

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 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)

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.

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).
