The short version

Michael Block is listed as a director on 3 SEC Form D filings by 1 issuer between Apr 2021 and Jun 2021: Riff Learning, Inc. (Newton, MA — other technology — 2021; $2.17M reported sold to 17 investors).

What this means One deal on file with the SEC, filed Jun 2021. A Form D is the notice a company files after it starts selling a private investment — it is a notice, not an approval.

Listed alongside Douglas Kim (3 shared filings) and Elizabeth Porter (3 shared filings).

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

Public records searched: federal courts (CourtListener / RECAP), SEC enforcement releases, state securities regulators (AZ, CA, DE, TX, WA) — 41 bankruptcy cases matching the name listed in Key records below.

What this means 41 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 3 public filings for Michael Block and found 6 differences: Offering amount changed between filings; No amendment in the last 12 months on an offering that may still be open; 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

6 differences found between the filings for Michael Block (compared 3 filings on Oct 24, 2026)

Note · Apr 20, 2021 – Jun 10, 2021

Offering amount changed between filings — Riff Learning, Inc.

The Apr 20, 2021 filing says $2,393,000 offered; the Jun 10, 2021 Form D/A says $2,399,391.

What this means The target raise changed. Raising the cap is common when a deal grows; ask whether the extra money has the same terms and use.

Note · Apr 16, 2021 – Apr 20, 2021

Offering amount changed between filings — Riff Learning, Inc.

The Apr 16, 2021 filing says $1,500,000 offered; the Apr 20, 2021 Form D/A says $2,393,000.

What this means The target raise changed. Raising the cap is common when a deal grows; ask whether the extra money has the same terms and use.

Sources
Note · Apr 12, 2021 – Jun 10, 2021

No amendment in the last 12 months on an offering that may still be open — Riff Learning, Inc. (latest filing Jun 10, 2021)

The latest filing for this offering is dated Jun 10, 2021 (first sale Apr 12, 2021). It reports $2,172,856 sold of $2,399,391 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.

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.
