The short version

Ivor Royston is listed as an executive officer and director on 25 SEC Form D filings by 6 issuers between Sep 2009 and Aug 2025. Largest by amount reported sold: Viracta Subsidiary, Inc.

What this means A repeat sponsor — 6 separate companies raised money with this person listed as executive officer and director, over about 16 years. Across those companies the filings report $108.5M sold in total.

Listed alongside Richard Ghalie (9 shared filings), James Woody (8 shared filings), Bruce E. Gerhardt (7 shared filings), Bruce Huebner (6 shared filings), David F. Hale (6 shared filings) and 72 others.

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

Public records searched: federal courts (CourtListener / RECAP), SEC enforcement releases, state securities regulators (AZ, CA, DE, TX, WA) — 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 25 public filings for Ivor Royston and found 13 differences, 1 worth asking the sponsor about: Form D filed 66 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.

13 differences found between the filings for Ivor Royston — 1 worth asking about (compared 25 filings on Oct 24, 2026)

Worth asking · Jun 16, 2025 – Aug 21, 2025

Form D filed 66 days after the first sale — Lions Mate With Lions, Ltd Liability Co

The filing says the first sale was Jun 16, 2025. The Form D was filed Aug 21, 2025 — 66 days later. The rule: a Form D is generally due within 15 days after the first sale, so this one is 51 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.

Ivor Royston's role changed at Viracta Subsidiary, Inc.: director → executive officer, director

The Apr 4, 2012 filing lists Ivor Royston as director; the Apr 5, 2017 Form D lists executive officer, director.

What this means Roles on Form D are self-reported by the issuer. A change can mean a real change in who runs the company, or just a different box ticked. Ask who makes decisions today.

What this means The issuer described its business differently on different forms. Often it is just a different box ticked; sometimes the deal itself changed. Ask which business your money is in.

Same name, different state: "Ivor Royston" (MA) is a separate record

This page covers filings where the address state is CA or MT. A separate record, "Ivor Royston" with address state MA, is listed on 5 filings — most recently by Syndax Pharmaceuticals Inc (Jun 15, 2015). Both records have filings in the same period (Nov 14, 2013 to Jun 15, 2015).

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.

CA on 22 filings (Sep 21, 2009 to Aug 21, 2025); MT on 3 filings (Apr 22, 2010 to Jun 21, 2011).

What this means The address on a Form D is usually the company's, not the person's home, so this often just reflects different companies. It can also mean a move. Nothing wrong by itself.

The Apr 22, 2010 filing lists a minimum of $20,000; the May 28, 2010 Form D/A lists $5,000.

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 6

Every issuer that named Ivor Royston on a Form D, newest first. A Form D is the notice a company files after it starts selling a private investment.
