The short version

Leo Addimando is listed as an executive officer on 10 SEC Form D filings by 8 issuers between Feb 2016 and Mar 2024. Largest by amount reported sold: Alterra IOS Venture II, LP (Conshohocken, PA — commercial — 2021–2022; $520M reported sold to 91 investors), Alterra IOS Venture III NM Sidecar, LP (Bryn Mawr, PA — commercial — 2024; $25M reported sold to 1 investors), 300 Heinz Partners, LLC (Blue Bell, PA — residential — 2017; $9.36M reported sold to 104 investors), 777 Partners, LP (Blue Bell, PA — commercial — 2017; $2.88M reported sold to 24 investors), 5th Street Partners, LP (Philadelphia, PA — commercial — 2016; $1.93M reported sold to 13 investors) and 3 more (all listed below).

What this means A repeat sponsor — 8 separate companies raised money with this person listed as executive officer, over about 8 years. Across those companies the filings report $561.3M sold in total.

Listed alongside Jeff Pustizzi (6 shared filings), Matthew Pfeiffer (6 shared filings), Alterra IOS Venture II GP, LLC (5 shared filings, management entity), Axios Real Estate Partners, LLC (4 shared filings, management entity), Jeffrey Pustizzi (4 shared filings) and 16 others.

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

All 8 issuers belong to the sponsor group Frank Seidman Irrevocable (202 issuers, $2.44B reported sold, 2009–2026).

What this means A sponsor group is one team that sets up a new company for each deal. Frank Seidman Irrevocable has 202 companies on file and $2.44B 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 10 public filings for Leo Addimando and found 6 differences, 1 worth asking the sponsor about: Form D filed 100 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

6 differences found between the filings for Leo Addimando — 1 worth asking about (compared 10 filings on Oct 24, 2026)

Worth asking · Dec 15, 2021 – Mar 25, 2022

Form D filed 100 days after the first sale — Alterra IOS Venture II Master, LP

The filing says the first sale was Dec 15, 2021. The Form D was filed Mar 25, 2022 — 100 days later. The rule: a Form D is generally due within 15 days after the first sale, so this one is 85 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 · Apr 21, 2017 – Jun 7, 2017

Form D filed 47 days after the first sale — 777 Partners, LP

The filing says the first sale was Apr 21, 2017. The Form D was filed Jun 7, 2017 — 47 days later. The rule: a Form D is generally due within 15 days after the first sale, so this one is 32 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 · Dec 21, 2021 – Mar 22, 2022

Offering amount changed between filings — Alterra IOS Venture II, LP

The Dec 21, 2021 filing says $400,000,000 offered; the Mar 22, 2022 Form D/A says $520,000,000.

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 · Dec 15, 2021 – Dec 22, 2022

No amendment in the last 12 months on an offering that may still be open — Alterra IOS Venture II Master, LP (latest filing Dec 22, 2022)

The latest filing for this offering is dated Dec 22, 2022 (first sale Dec 15, 2021). It reports $1,905,000 sold of $524,000,000 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
Note · Apr 4, 2017 – Apr 19, 2017

No amendment in the last 12 months on an offering that may still be open — 300 Heinz Partners, LLC (latest filing Apr 19, 2017)

The latest filing for this offering is dated Apr 19, 2017 (first sale Apr 4, 2017). It reports $9,358,500 sold of $13,950,000 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
Note · Mar 25, 2022

Formed in 2022 per the latest filing, but activity is dated 2021 — Alterra IOS Venture II Master, LP

The issuer's latest filing says it was formed in 2022. The Mar 25, 2022 filing says the first sale was Dec 15, 2021 — before that year.

What this means A company cannot sell before it exists, so one of the two dates is likely a typo on the form. Ask the sponsor for the formation document.

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.

2 of 8 offerings report sales commissions totalling $12,500; 0 report finder's fees; 2 report proceeds to related persons totalling $625,000. (includes amounts the issuer reported as estimates)

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).
