The short version

William C. Blake is listed as an executive officer on 1 SEC Form D filing by 1 issuer in Nov 2014: D-Wave Systems Inc. (Burnaby, British Columbia, Canada (as filed: A1) — other technology — 2014; $28.4M reported sold to 33 investors).

What this means One deal on file with the SEC, filed Nov 2014. A Form D is the notice a company files after it starts selling a private investment — it is a notice, not an approval.

Listed alongside Alexei A. Andreev (1 shared filing), Don Listwin (1 shared filing), Geoff Catherwood (1 shared filing), Geordie Rose (1 shared filing), J. Haig Deb Farris (1 shared filing) and 8 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.

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 1 public filing for William C. Blake and found 3 differences: Same name, different state: "William Blake" (IL) is a separate record; Same name, different state: "William Blake" (MN or MI) is a separate record; 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.

3 differences found between the filings for William C. Blake (compared 1 filing on Oct 24, 2026)

Note · May 29, 2019 – Feb 17, 2026

Same name, different state: "William Blake" (IL) is a separate record

This page covers filings where the address state is A1. A separate record, "William Blake" with address state IL, is listed on 5 filings — most recently by Dentologie Enterprises, Inc.

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.
