The short version

Mason Sleeper is listed as an executive officer on 12 SEC Form D filings by 11 issuers between Mar 2017 and Jan 2024. Largest by amount reported sold: Praedium X Middle-Income Housing Fund, L.P. (New York, NY — pooled investment fund — 2019–2021; $215M reported sold to 10 investors), Praedium IX Multifamily Value Fund, L.P. (New York, NY — pooled investment fund — 2017; $115.9M reported sold to 5 investors), Versol Drive Member LLC (New York, NY — reits and finance — 2024; $125K reported sold to 125 investors), TPF X JV Holdco I LLC (New York, NY — reits and finance — 2022; $125K reported sold to 125 investors), TPF X JV Holdco II LLC (New York, NY — reits and finance — 2022; $125K reported sold to 125 investors) and 6 more (all listed below).

What this means That is a lot of deals — 11 separate companies raised money with this person listed as executive officer, over about 7 years. Across those companies the filings report $332M sold in total.

Listed alongside Christopher Hughes (12 shared filings), Ronald W. Strobl (12 shared filings), Russell L. Appel (12 shared filings), Adam McGovern (11 shared filings), Peter A. Calatozzo (11 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 Mason. Each name links to their own page.

All 11 issuers belong to the sponsor group Tpf (13 issuers, $507.8M reported sold, 2013–2024).

What this means A sponsor group is one team that sets up a new company for each deal. Tpf has 13 companies on file and $507.8M 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.

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

2 differences found between the filings for Mason Sleeper (compared 12 filings on Oct 24, 2026)

Note · Oct 4, 2019 – Apr 12, 2021

No amendment in the last 12 months on an offering that may still be open — Praedium X Middle-Income Housing Fund, L.P. (latest filing Apr 12, 2021)

The latest filing for this offering is dated Apr 12, 2021 (first sale Oct 4, 2019). It reports $214,974,000 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.

Note · Mar 16, 2017 – Mar 31, 2017

No amendment in the last 12 months on an offering that may still be open — Praedium IX Multifamily Value Fund, L.P. (latest filing Mar 31, 2017)

The latest filing for this offering is dated Mar 31, 2017 (first sale Mar 16, 2017). It reports $115,942,028 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.

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).

Deals 11

Every issuer that named Mason Sleeper on a Form D, newest first. A Form D is the notice a company files after it starts selling a private investment.
