All 7 issuers belong to the sponsor group Secondmarket (38 issuers, $246.7M reported sold, 2023–2026).

What this means A sponsor group is one team that sets up a new company for each deal. Secondmarket has 38 companies on file and $246.7M 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 7 public filings for Transistor Ventures and found 4 differences: No amendment in the last 12 months on an offering that may still be open; Address moved from Claymont, DE to New York City, NY; 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 found between the filings for Transistor Ventures (compared 7 filings on Oct 24, 2026)

Note · Jun 30, 2025 – Jul 11, 2025

No amendment in the last 12 months on an offering that may still be open — WPX Fund I Jun 2025 a Series of SecondMarket Growth LLC (latest filing Jul 11, 2025)

The latest filing for this offering is dated Jul 11, 2025 (first sale Jun 30, 2025). It reports $262,500 sold of $120,000,000 offered. No later amendment is in our index as of Oct 24, 2026.

What this means SEC rules expect a yearly amendment while an offering is still going. The raise may simply have ended — a Form D does not say when it closed. Ask the sponsor whether the offering closed, when, and at what amount.

Address moved from Claymont, DE to New York City, NY — TV AI Fund IB a Series of SecondMarket Growth LLC

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 entity is listed on (latest filing per offering, per issuer).
