The short version

Keith Oster is listed as an executive officer, director, and promoter on 4 SEC Form D filings by 4 issuers between Jun 2011 and Sep 2021: Ironwood Power Services, LLC (Henrietta, NY — investing — 2021; $37.5M reported sold to 11 investors), Empeiria BBRSS Holdings LLC (New York, NY — investing — 2018; $15.2M reported sold to 8 investors), Empeiria Investors LLC (New York, NY — investing — 2011; $3.96M reported sold to 30 investors) and Tank Partners Equipment Company, Inc. (New York, NY — manufacturing — 2019; $2.25M reported sold to 10 investors).

What this means A repeat sponsor — 4 separate companies raised money with this person listed as executive officer, director, and promoter, over about 10 years. Across those companies the filings report $59M sold in total.

Listed alongside Alan B. Menkes (4 shared filings), Joseph Fong (3 shared filings), ANDREW MOLINARI (1 shared filing), Charles Sheridan (1 shared filing), Janice O. Wilcox (1 shared filing) and 6 others.

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

All 4 issuers belong to the sponsor group Cyprium (11 issuers, $1.23B reported sold, 2011–2024).

What this means A sponsor group is one team that sets up a new company for each deal. Cyprium has 11 companies on file and $1.23B 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) — 2 bankruptcy cases matching the name listed in Key records below.

What this means 2 records came back. Each one is listed below with a link to the original document and a line saying why it matched. A name match is not proof it is the same person or company — read the why line and the document. Being sued or named in a release is an accusation, not a finding.

We compared 4 public filings for Keith Oster and found 7 differences, 2 worth asking the sponsor about: 4 bankruptcy cases name the subject or team members; 25% of the money raised went to insiders; 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.

25% of the money raised went to insiders — Ironwood Power Services, LLC

The Sep 9, 2021 Form D reports $37,550,000 sold and $9,550,000 of the proceeds used for payments to officers, directors or promoters (marked as an estimate). Issuer's note: "Some of the executive officers and directors received equity as a part of the transaction.".

What this means The filing reports how much of the money raised was paid to insiders. Over 10% is high for most deals. Ask what it paid for.

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.

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).

Registrations and other filings

Business registration (state registry / Secretary of State)

Individuals are not matched to business registrations — registries list companies, and a name alone is not enough to tie a person to one. Officers and managers appear by name inside each matched company's record on the issuer pages. Registries searched: AL (Alabama Secretary of State — Business Entity Records (arc-sos.state.al.us), searched by issuer name, data as of Oct 24, 2026); CO (Colorado Secretary of State — Business Entities in Colorado (data.colorado.gov), data as of Oct 23, 2026); CT (Connecticut Secretary of the State — Business Registry (data.ct.gov), data as of Oct 24, 2026); FL (Florida Department of State, Division of Corporations — quarterly corporate data file (Sunbiz), data as of Oct 7, 2026); NY (New York Department of State — Corporations and Other Entities (data.ny.gov: All Filings + Active Corporations), data as of Oct 20, 2026); OR (Oregon Secretary of State — Active Businesses, All (data.oregon.gov), data as of Oct 20, 2026); PA (Pennsylvania Department of State — Registered Businesses, Current (data.pa.gov), data as of Oct 6, 2026); TX (Texas Comptroller — Active Franchise Taxpayers incl. Secretary of State file data (data.texas.gov), data as of Oct 24, 2026). Registries of other states have not been searched: many publish no bulk file and require a CAPTCHA or bot challenge on their search page, which we do not bypass (Delaware, for example, offers no public bulk file).

Adviser registration (Form ADV)

None of the 4 issuers this person is listed on appears in Form ADV (searched 24,962 advisers as of Oct 2, 2026). A person is never an adviser firm; Form ADV is checked for the issuers and the management companies they are listed with.
