The short version

Darin Feinstein is listed as an executive officer and director on 6 SEC Form D filings by 2 issuers between Jun 2021 and Sep 2022: Blockcap, Inc. (Austin, TX — industry reported as "Other" — 2021; $36.3M reported sold to 85 investors) and Core Scientific, Inc./tx (Austin, TX — computers — 2022; 1 investors reported).

What this means 2 separate companies raised money with this person listed as executive officer and director. Across those companies the filings report $36.3M sold in total.

Listed alongside Harlin Dean (5 shared filings), Peter J. Novak (5 shared filings), Christel Sice (4 shared filings), Clark Swanson (4 shared filings), Larry Rudolph (4 shared filings) and 9 others.

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

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) — 1 court case matching the name listed in Key records below.

What this means 1 record came back, including 1 court case still open — open cases can take years and cost money. 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 Darin Feinstein and found 6 differences, 1 worth asking the sponsor about: 5 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.

Same name, different state: "Darin Feinstein" (NV) is a separate record

This page covers filings where the address state is TX. A separate record, "Darin Feinstein" with address state NV, is listed on 5 filings — most recently by SpaceX Investors 5 LLC (May 6, 2026). The two records do not overlap in time: this page runs Jun 15, 2021 to Sep 9, 2022; the other runs Mar 14, 2018 to Apr 25, 2018.

What this means Could be the same person who moved, or two people with the same name. We keep them apart until a filing ties them together. Check both pages before you decide.

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.

"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.
