The short version

Herbert T. Sears is listed as an executive officer and director on 6 SEC Form D filings by 4 issuers between Nov 2008 and Feb 2020: ION Clean Energy, Inc. (Boulder, CO — environmental services — 2019; $70M reported sold to 19 investors), T-REX OIL, INC. (Broomfield, CO — industry reported as "Other" — 2016; $250K reported sold to 64 investors), Eco2Source, Inc. (Littleton, CO — industry reported as "Other" — 2020; $20K reported sold to 3 investors) and South Park Technology, Inc. (Parker, CO — other energy — 2008; $2,000 reported sold to 2 investors).

What this means A repeat sponsor — 4 separate companies raised money with this person listed as executive officer and director, over about 12 years. Across those companies the filings report $70.3M sold in total.

Listed alongside DONALD WALFORD (3 shared filings), ALFRED BROWN (2 shared filings), ERIK MEULEMAN (2 shared filings), JON NICOLAYSEN (2 shared filings), MARTIN GOTTLOB (2 shared filings) and 8 others.

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

1 of the issuers belongs to the sponsor group Ion (2 issuers, $70.1M reported sold, 2009–2024).

What this means A sponsor group is one team that sets up a new company for each deal. Ion has 2 companies on file and $70.1M 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, CT, DE, FINRA, GA, HI, ID, IL, KS, KY, LA, MA, MD, ME, MI, MO, MS, MT, NASAA, NC, ND, NH, NM, NV, OK, OR, PA, RI, SC, SD, TN, TX, VT, WA, WI, WV, WY) — 3 bankruptcy cases matching the name listed in Key records below.

What this means 3 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 6 public filings for Herbert T. Sears and found 8 differences, 2 worth asking the sponsor about: 75% of the money raised went to insiders; 4 Form Ds were filed more than 15 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

Sources
Worth asking · Nov 24, 2008

75% of the money raised went to insiders — South Park Technology, Inc.

The Nov 24, 2008 Form D reports $2,000 sold and $1,500 of the proceeds used for payments to officers, directors or promoters (marked as an estimate).

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.

Sources

Herbert T. Sears appears on 2 deals that stopped filing before reaching their target

T-REX OIL, INC. (last filing Jul 30, 2019; $250,000 sold of $7,000,000); South Park Technology, Inc. (last filing Nov 24, 2008; $2,000 sold of $75,000). Each has no filing in more than two years and reported under half its target sold.

What this means An issuer whose last filing is more than two years old and reported under half its target sold. The raise may have closed early or quietly stopped. Ask what happened to each.

Sources
Worth asking · Oct 24, 2008 – Feb 5, 2020

4 Form Ds were filed more than 15 days after the first sale

Form D filed 71 days after the first sale — Eco2Source, Inc. · Form D filed 20 days after the first sale — ION Clean Energy, Inc. · Form D filed 20 days after the first sale — T-REX OIL, INC. · Form D filed 31 days after the first sale — South Park Technology, Inc.

What this means Late notices are common and carry no penalty by themselves. A pattern of late paperwork is worth asking the sponsor about.

Sources
Note · Oct 24, 2008 – Feb 5, 2020

4 offerings have no amendment in the last 12 months and may still be open

No amendment in the last 12 months on an offering that may still be open — Eco2Source, Inc.

(latest filing May 17, 2016) · No amendment in the last 12 months on an offering that may still be open — T-REX OIL, INC. (latest filing Mar 29, 2016) · No amendment in the last 12 months on an offering that may still be open — South Park Technology, Inc. (latest filing Nov 24, 2008)

What this means SEC rules expect a yearly amendment while an offering is still going. Ask the sponsor which of these raises have closed.

Sources
Note · Mar 29, 2016 – May 17, 2016

Herbert T. Sears's role changed at T-REX OIL, INC.: director → executive officer, director

The Mar 29, 2016 filing lists Herbert T. Sears as director; the May 17, 2016 Form D lists executive officer, director.

What this means Roles on Form D are self-reported by the issuer. A change can mean a real change in who runs the company, or just a different box ticked. Ask who makes decisions today.

Sources
Note · Nov 24, 2008 – Mar 29, 2016

Herbert T. Sears is written 2 different ways on the filings

listed as "Herbert T. Sears" on 3 filings (from Nov 24, 2008), and "Herbert Sears" on 3 filings (from Mar 29, 2016).

What this means Same person, written differently — a middle name or suffix left off, or spelled another way. It is normal, but check that the full legal name matches your subscription documents.

Sources
Note · May 29, 2019 – Jun 19, 2019

Reported revenue range changed between filings — ION Clean Energy, Inc.

"No Revenues" (May 29, 2019); then "$1,000,001 - $5,000,000" (Jun 19, 2019).

What this means This is the size band the issuer picks for itself on the form. A change can mean the business grew or shrank — or that it chose not to say. Ask for current numbers.

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).
