The short version

Mark Platshon is listed as a director and promoter on 5 SEC Form D filings by 4 issuers between Sep 2013 and Jul 2024: Peloton Technology, Inc. (Mountain View, CA — industry reported as "Other" — 2013; $65.3M reported sold to 26 investors), Tokamak Investors QP, LLC (Menlo Park, CA — pooled investment fund — 2021; $34M reported sold to 108 investors), Tokamak Investors, LLC (Menlo Park, CA — pooled investment fund — 2021; $5.35M reported sold to 111 investors) and T1E SPV, a series of Redwoods Climate Capital Co- Investment, LP (Menlo Park, CA — pooled investment fund — 2024; $3.4M reported sold to 26 investors).

What this means A repeat sponsor — 4 separate companies raised money with this person listed as director and promoter, over about 11 years. Across those companies the filings report $108.1M sold in total.

Listed alongside Icebreaker Ventures LLC (2 shared filings, management entity), Justin Ashton (2 shared filings), Redwoods Capital Partners, LLC (2 shared filings, management entity), David Lyons (1 shared filing), Joshua Switkes (1 shared filing) and 1 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.

3 of the issuers belong to the sponsor group Tokamak (3 issuers, $42.8M reported sold, 2021–2024).

What this means A sponsor group is one team that sets up a new company for each deal. Tokamak has 3 companies on file and $42.8M 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 (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 5 public filings for Mark Platshon and found 5 differences: Offering amount changed between filings; No amendment in the last 12 months on an offering that may still be open; 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

5 differences found between the filings for Mark Platshon (compared 5 filings on Oct 24, 2026)

Note · Apr 15, 2024 – Jul 29, 2024

Offering amount changed between filings — T1E SPV, a series of Redwoods Climate Capital Co- Investment, LP

The Apr 15, 2024 filing says an indefinite amount offered; the Jul 29, 2024 Form D/A says $3,500,000.

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 · May 23, 2013 – Sep 20, 2013

Offering amount changed between filings — Peloton Technology, Inc.

The May 23, 2013 filing says $1,250,000 offered; the Sep 20, 2013 Form D/A says $1,499,999.

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 · Mar 7, 2024 – Jul 29, 2024

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).
