The short version

Mark Blackwell is listed as a director on 7 SEC Form D filings by 4 issuers between Jul 2011 and Jan 2024: Builders VC Entrepreneurs Fund II, L.P. (San Francisco, CA — pooled investment fund — 2020–2021; $235.9M reported sold to 57 investors), Builders VC Fund II, L.P.

(San Francisco, CA — pooled investment fund — 2024).

What this means A repeat sponsor — 4 separate companies raised money with this person listed as director, over about 13 years. Across those companies the filings report $578.5M sold in total.

Listed alongside Alex Kinnier (5 shared filings), Amit Mehta (5 shared filings), James Kim (5 shared filings), Jocelyn Doe (5 shared filings), Mark Goldstein (5 shared filings) and 6 others.

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

The issuers belong to 2 sponsor groups: Builders (7 issuers, $471.9M reported sold, 2020–2024) and Zero Motorcycles (2 issuers, $115.2M reported sold, 2010–2026).

What this means This person is listed across more than one sponsor team; each group page shows that team's full track record.

Public records searched: federal courts (CourtListener / RECAP), SEC enforcement releases, state securities regulators (AZ, CA, DE, TX, WA) — 17 bankruptcy cases matching the name listed in Key records below.

What this means 17 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 Mark Blackwell and found 2 differences: 4 offerings have no amendment in the last 12 months and may still be open; Same name, different state: "Mark Brandon Blackwell" (VA) is a separate record.

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

2 differences found between the filings for Mark Blackwell (compared 7 filings on Oct 24, 2026)

Note · Jun 24, 2011 – Oct 28, 2021

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 — Builders VC Entrepreneurs Fund II, L.P. (latest filing Oct 28, 2021) · No amendment in the last 12 months on an offering that may still be open — Builders VC Fund II, L.P. (latest filing Oct 28, 2021) · No amendment in the last 12 months on an offering that may still be open — Zero Motorcycles Inc (latest filing Oct 3, 2011) · No amendment in the last 12 months on an offering that may still be open — Zero Motorcycles Inc (latest filing Jul 6, 2011)

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

Note · May 1, 2026

Same name, different state: "Mark Brandon Blackwell" (VA) is a separate record

This page covers filings where the address state is CA. A separate record, "Mark Brandon Blackwell" with address state VA, is listed on 1 filing — most recently by Kimchi Pop IT LLC (May 1, 2026). The two records do not overlap in time: this page runs Jul 6, 2011 to Jan 26, 2024; the other has one filing dated May 1, 2026.

What this means Could be the same person who moved, or two people with the same name. 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.
