The short version

Base4 General Partner LLC is a management entity listed as an executive officer on 8 SEC Form D filings by 3 issuers between Aug 2022 and Mar 2026: Base4 Onshore Fund LP (Menlo Park, CA — pooled investment fund — 2022–2024; $67.9M reported sold to 12 investors), Base4 Private Ventures III LP (Menlo Park, CA — pooled investment fund — 2023–2026; $9.5M reported sold to 9 investors) and Base4 Private Ventures IV LP (Menlo Park, CA — pooled investment fund — 2024–2026; $9.28M reported sold to 7 investors).

What this means A repeat sponsor — 3 separate companies raised money with this person listed as executive officer, over about 4 years. Across those companies the filings report $86.7M sold in total.

Listed alongside Amol Jain (8 shared filings) and Base4 Capital LP (8 shared filings, management entity).

What this means These are the other officers, directors or promoters the companies named on the same forms — the team around Base4. Each name links to their own page.

All 3 issuers belong to the sponsor group Base4 (3 issuers, $86.7M reported sold, 2022–2026).

What this means A sponsor group is one team that sets up a new company for each deal. Base4 has 3 companies on file and $86.7M 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 (AK, AL, AR, AZ, CA, CO, CT, DC, DE, FINRA, FL, GA, HI, ID, IL, KS, KY, LA, MA, MD, ME, MI, MO, MS, MT, NASAA, NC, ND, NH, NM, NV, NY, OH, OK, OR, PA, RI, SC, SD, TN, TX, UT, 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 8 public filings for Base4 General Partner LLC and found 3 differences, 1 worth asking the sponsor about: Investor count went down between filings; 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

3 differences found between the filings for Base4 General Partner LLC — 1 worth asking about (compared 8 filings on Oct 24, 2026)

Worth asking · Aug 24, 2022 – Aug 24, 2023

Investor count went down between filings — Base4 Onshore Fund LP

The Aug 24, 2022 filing reports 12 investors; the Aug 24, 2023 Form D/A reports 11 investors.

What this means Investor counts normally only grow. A smaller number can mean investors left or were refunded, or a count was corrected. Ask the sponsor what happened.

Note · Jan 18, 2022 – Aug 23, 2024

No amendment in the last 12 months on an offering that may still be open — Base4 Onshore Fund LP (latest filing Aug 23, 2024)

The latest filing for this offering is dated Aug 23, 2024 (first sale Jan 18, 2022). It reports $67,943,914 sold of an indefinite amount 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.

Form D/A · Aug 23, 2024 ↗Base4 Onshore Fund LP — PartnerFacts page ↗

Note · Jan 25, 2022 – Aug 24, 2022

Address moved from New York, NY to Menlo Park, CA — Base4 Onshore Fund LP

The people listed on the Jan 25, 2022 filing give New York, NY; on the Aug 24, 2022 filing they give Menlo Park, CA. The address now on file (1300 El Camino Real, Suite 100, Menlo Park, CA) is a registered-agent or shared-office address used by 232 issuers.

What this means A registered agent's address is a mailbox, not where the team works. Ask where the business actually operates.

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.
