The short version

David Sidoo is listed as an executive officer, director, and promoter on 7 SEC Form D filings by 3 issuers between Oct 2010 and Aug 2019: East West Petroleum Corp. (Vancouver, British Columbia, Canada (as filed: A1) — oil and gas — 2010–2011; $5.78M reported sold to 29 investors), Advantage Lithium Corp. (Vancouver, British Columbia, Canada (as filed: A1) — industry reported as "Other" — 2016–2019; $799K reported sold to 16 investors) and Liberty Defense Holdings, Inc. (Vancouver, British Columbia, Canada (as filed: A1) — industry reported as "Other" — 2019; $160K reported sold to 10 investors).

What this means A repeat sponsor — 3 separate companies raised money with this person listed as executive officer, director, and promoter, over about 9 years. Across those companies the filings report $6.74M sold in total.

Listed alongside Nick DeMare (5 shared filings), Callum Grant (4 shared filings), Ross McElroy (3 shared filings), Devinder Randhawa (2 shared filings), Greg Renwick (2 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 David. Each name links to their own page.

1 of the issuers belongs to the sponsor group East West (2 issuers, $5.89M reported sold, 2010–2026).

What this means A sponsor group is one team that sets up a new company for each deal. East West has 2 companies on file and $5.89M 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, CT, DE, FINRA, GA, HI, ID, IL, KS, KY, LA, MA, MD, ME, MI, MO, MS, MT, NASAA, NC, ND, NH, NM, NV, OK, OR, PA, RI, SC, SD, TN, TX, 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 David Sidoo and found 8 differences, 1 worth asking the sponsor about: Paid seller listed without a CRD number: Haywood Securities Inc; 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

8 differences found between the filings for David Sidoo — 1 worth asking about (compared 7 filings on Oct 24, 2026)

Note · Aug 28, 2019

David Sidoo appears on 1 deal that stopped filing before reaching its target

Advantage Lithium Corp. (last filing Aug 28, 2019; $798,918 sold of $6,534,694). Each has no filing in more than two years and reported under half its target sold.

What this means An issuer whose last filing is more than two years old and reported under half its target sold. The raise may have closed early or quietly stopped. Ask what happened to each.

Sources
Worth asking · Jan 5, 2011

Paid seller listed without a CRD number: Haywood Securities Inc. — East West Petroleum Corp.

Haywood Securities Inc. is listed as receiving sales compensation on 1 filing (Jan 5, 2011) with no FINRA CRD number given.

What this means People paid to sell securities normally hold a FINRA registration with a CRD number. Without one we cannot look them up on BrokerCheck. Ask who they are and whether they are registered.

Sources
Note · Aug 12, 2019 – Aug 28, 2019

Form D filed 16 days after the first sale — Advantage Lithium Corp.

The filing says the first sale was Aug 12, 2019. The Form D was filed Aug 28, 2019 — 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 · Feb 17, 2017 – Mar 6, 2017

Form D filed 17 days after the first sale — Advantage Lithium Corp.

The filing says the first sale was Feb 17, 2017. The Form D was filed Mar 6, 2017 — 17 days later. The rule: a Form D is generally due within 15 days after the first sale, so this one is 2 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 · Sep 29, 2010 – Nov 6, 2017

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 — Advantage Lithium Corp. (latest filing Nov 6, 2017) · No amendment in the last 12 months on an offering that may still be open — Advantage Lithium Corp. (latest filing Mar 6, 2017) · No amendment in the last 12 months on an offering that may still be open — East West Petroleum Corp. (latest filing Jan 5, 2011) · No amendment in the last 12 months on an offering that may still be open — East West Petroleum Corp. (latest filing Oct 13, 2010)

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 · Nov 6, 2017 – Aug 28, 2019

David Sidoo's role changed at Advantage Lithium Corp.: executive officer, director, promoter → director

The Nov 6, 2017 filing lists David Sidoo as executive officer, director, promoter; the Aug 28, 2019 Form D lists 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.

Sources
Note · Oct 28, 2016 – Nov 6, 2017

Offering amount changed between filings — Advantage Lithium Corp.

The Oct 28, 2016 filing says $6,247,994 offered; the Nov 6, 2017 Form D/A says $6,534,694.

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 · Oct 28, 2016 – Aug 28, 2019

Reported revenue range changed between filings — Advantage Lithium Corp.

"No Revenues" (Oct 28, 2016); then "Decline to Disclose" (Aug 28, 2019).

What this means This is the size band the issuer picks for itself on the form. A change can mean the business grew or shrank — or that it chose not to say. Ask for current numbers.

Sources
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).
