What this means That is a lot of deals — 14 separate companies raised money with this person listed as executive officer, director, and promoter, over about 10 years. Across those companies the filings report $943.2M sold in total.

Listed alongside An-Yen Hu (6 shared filings), Chetan Puttagunta (6 shared filings), Eric H. Vishria (6 shared filings), Eric Koslow (6 shared filings), Everett Randle (6 shared filings) and 15 others.

The issuers belong to 3 sponsor groups: Benchmark (28 issuers, $3.26B reported sold, 2011–2026), Jack Altman (3 issuers, $2M reported sold, 2020–2021) and Alt (2 issuers, $425M reported sold, 2024–2025).

What this means This person is listed across more than one sponsor team; each group page shows that team's full track record.

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 22 public filings for Jack Altman and found 10 differences, 1 worth asking the sponsor about: 7 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.

Worth asking · Apr 19, 2016 – Jul 28, 2026

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

Form D filed 158 days after the first sale — Copilot Labs, Inc. \ DE · Form D filed 103 days after the first sale — Degree, Inc. · Form D filed 151 days after the first sale — Degree, Inc. · Form D filed 20 days after the first sale — Antares Nuclear, Inc. · Form D filed 32 days after the first sale — Degree, Inc. · and 2 more

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 · Sep 10, 2025 – Sep 19, 2025

No amendment in the last 12 months on an offering that may still be open — Antares Nuclear, Inc. (latest filing Sep 19, 2025)

The latest filing for this offering is dated Sep 19, 2025 (first sale Sep 10, 2025). It reports $51,045,266 sold of $79,534,995 offered. No later amendment is in our index as of Oct 24, 2026.

Note · Nov 25, 2019 – Apr 7, 2021

Jack Altman's role changed at Degree, Inc.: executive officer, director → executive officer, director, promoter

The Nov 25, 2019 filing lists Jack Altman as executive officer, director; the Apr 7, 2021 Form D lists executive officer, director, promoter.

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 · Jul 21, 2021 – Jun 12, 2023

Same name, different state: "Jack Altman" (TX) is a separate record

This page covers filings where the address state is CA. A separate record, "Jack Altman" with address state TX, is listed on 2 filings — most recently by Verifiable Inc. (Jun 12, 2023). Both records have filings in the same period (Jul 21, 2021 to Jun 12, 2023).

What this means Two records with one name were active at the same time. That can be one person listing different company addresses, or two different people. We keep them apart until a filing ties them together. Check both pages before you decide.

Sources
Note · Oct 9, 2024 – Sep 19, 2025

Address moved from Redondo Beach, CA to Torrance, CA — Antares Nuclear, Inc.

The people listed on the Oct 9, 2024 filing give Redondo Beach, CA; on the Sep 19, 2025 filing they give Torrance, CA.

What this means Businesses move; this just shows the two places and dates. If you were told one city and the forms say another, ask which is current.

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.

A shared address can mean the same team, a shared office building or a registered agent. It is a lead, not a conclusion.

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 14 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.

Other offering types (Regulation A and Regulation Crowdfunding)

Searched SEC Regulation A Data Sets (Forms 1-A, 1-K, 1-Z; 2015 Q2 → 2026 Q3); SEC Crowdfunding Offerings Data Sets (Form C family; 2016 Q2 → 2026 Q3); EDGAR form index for 2026 Q3 → 2026 Q4 (51,358 records as of Oct 23, 2026, 8:41 PM ET) — nothing matched this name.

Property records none — individuals are not matched

Property records are matched to companies only, never to individuals, so none are matched to Jack Altman by design. Searched property records in Hillsborough County FL (Clerk recorded-document index Oct 14, 2026 to Oct 15, 2026 + FL DOR 2026 ownership roll), Miami-Dade County FL (FL DOR 2026 ownership roll), Harris County TX (HCAD 2026 ownership roll), Dallas County TX (DCAD 2026 ownership roll), New York City ACRIS documents and PLUTO ownership rows already retrieved for other issuers, Cook County IL sale and ownership rows already retrieved for other issuers (814,874 records as of Oct 23, 2026, 8:59 PM ET) for the 14 issuers this person is listed on — nothing matched.

Public profiles and social

Websites and social links of the issuers Jack Altman is listed on, as found in their SEC filings (Form C, Reg A, Form ADV, EDGAR profile) or on the sponsor's own site; none belongs to the person unless the sponsor's site says so. Checked Oct 24, 2026.
