The short version

Ari Horowitz is listed as an executive officer, director, and promoter on 6 SEC Form D filings by 5 issuers between Sep 2010 and Mar 2021: Leaven Ventures SolarP, LLC (New York, NY — pooled investment fund — 2021; $35.1M reported sold to 1 investors), Leaven Ventures SPV, LLC (New York, NY — pooled investment fund — 2021; $8.1M reported sold to 21 investors), Leaven Ventures EcommerceT, LLC (New York, NY — pooled investment fund — 2021; $7.1M reported sold to 30 investors), Leaven Ventures SolarP II, LLC (New York, NY — pooled investment fund — 2021; $3.64M reported sold to 2 investors) and Access Network Media & Technology Company, Inc. (New York, NY — industry reported as "Other" — 2010–2012; $1.7M reported sold to 20 investors).

What this means A repeat sponsor — 5 separate companies raised money with this person listed as executive officer, director, and promoter, over about 11 years. Across those companies the filings report $55.6M sold in total.

Listed alongside Barry Rubenstein (2 shared filings), Dan Pelson (2 shared filings), Eric Gertler (2 shared filings), Hudson Palm LLC (2 shared filings, management entity), Irwin Lieber (2 shared filings) and 7 others.

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

4 of the issuers belong to the sponsor group Leaven (4 issuers, $53.9M reported sold, 2021).

What this means A sponsor group is one team that sets up a new company for each deal. Leaven has 4 companies on file and $53.9M 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 6 public filings for Ari Horowitz and found 3 differences, 1 worth asking the sponsor about: Form D filed 520 days after the first sale; 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 Ari Horowitz — 1 worth asking about (compared 6 filings on Oct 24, 2026)

Worth asking · Jul 27, 2011 – Dec 28, 2012

Form D filed 520 days after the first sale — Access Network Media & Technology Company, Inc.

The filing says the first sale was Jul 27, 2011. The Form D was filed Dec 28, 2012 — 520 days later. The rule: a Form D is generally due within 15 days after the first sale, so this one is 505 days past that.

What this means The notice went in months after money was taken in. Late notices are common and carry no penalty by themselves, but it is fair to ask the sponsor why the paperwork lagged.

Sources
Note · Feb 16, 2021 – Mar 4, 2021

Form D filed 16 days after the first sale — Leaven Ventures SolarP, LLC

The filing says the first sale was Feb 16, 2021. The Form D was filed Mar 4, 2021 — 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 · Sep 16, 2010 – Sep 22, 2010

No amendment in the last 12 months on an offering that may still be open — Access Network Media & Technology Company, Inc. (latest filing Sep 22, 2010)

The latest filing for this offering is dated Sep 22, 2010 (first sale Sep 16, 2010). It reports $1,700,000 sold of $3,000,000 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.

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).
