The short version

Michael Lang is listed as a director on 5 SEC Form D filings by 2 issuers between Sep 2013 and Sep 2024: ProrataAI, Inc. (Pasadena, CA — other technology — 2024; $40M reported sold to 14 investors) and Film Track, Inc. (Studio City, CA — industry reported as "Other" — 2013–2014; $20M reported sold to 4 investors).

What this means 2 separate companies raised money with this person listed as director, over about 11 years. Across those companies the filings report $60M sold in total.

Listed alongside Bill Gross (3 shared filings), Dakin Sloss (3 shared filings), Marcia Goodstein (3 shared filings), Susan Aledort (3 shared filings), William E. Savage, Jr. (3 shared filings) and 5 others.

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) — 6 bankruptcy cases matching the name listed in Key records below.

What this means 6 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 5 public filings for Michael Lang and found 7 differences, 1 worth asking the sponsor about: Form D filed 182 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

7 differences found between the filings for Michael Lang — 1 worth asking about (compared 5 filings on Oct 24, 2026)

Worth asking · Mar 28, 2024 – Sep 26, 2024

Form D filed 182 days after the first sale — ProrataAI, Inc.

The filing says the first sale was Mar 28, 2024. The Form D was filed Sep 26, 2024 — 182 days later. The rule: a Form D is generally due within 15 days after the first sale, so this one is 167 days past that.

What this means The notice went in months after money was taken in. Late notices are common and carry no penalty by themselves, but it is fair to ask the sponsor why the paperwork lagged.

Sources
Note · Aug 2, 2024 – Sep 26, 2024

Form D filed 55 days after the first sale — ProrataAI, Inc.

The filing says the first sale was Aug 2, 2024. The Form D was filed Sep 26, 2024 — 55 days later. The rule: a Form D is generally due within 15 days after the first sale, so this one is 40 days past that.

What this means A late notice is common and carries no penalty by itself. It is worth asking the sponsor why the paperwork lagged.

Sources
Note · Aug 16, 2013 – Sep 4, 2013

Form D filed 19 days after the first sale — Film Track, Inc.

The filing says the first sale was Aug 16, 2013. The Form D was filed Sep 4, 2013 — 19 days later. The rule: a Form D is generally due within 15 days after the first sale, so this one is 4 days past that.

What this means A late notice is common and carries no penalty by itself. It is worth asking the sponsor why the paperwork lagged.

Sources
Note · Aug 16, 2013 – Sep 4, 2013

No amendment in the last 12 months on an offering that may still be open — Film Track, Inc. (latest filing Sep 4, 2013)

The latest filing for this offering is dated Sep 4, 2013 (first sale Aug 16, 2013). It reports $19,999,999 sold of $21,999,998 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.

Sources
Note · Aug 26, 2015

Same name, different state: "Michael Lang" (NY) is a separate record

This page covers filings where the address state is CA. A separate record, "Michael Lang" with address state NY, is listed on 1 filing — most recently by Music Labs, Inc. (Aug 26, 2015). Both records have filings in the same period (Aug 26, 2015).

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 · Jan 10, 2014

Same name, different state: "Michael Lang" (PA) is a separate record

This page covers filings where the address state is CA. A separate record, "Michael Lang" with address state PA, is listed on 1 filing — most recently by Nanovision Diagnostics, Inc. (Jan 10, 2014). Both records have filings in the same period (Jan 10, 2014).

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 25, 2010 – Jul 1, 2011

Same name, different state: "Michael Lang" (TX) is a separate record

This page covers filings where the address state is CA. A separate record, "Michael Lang" with address state TX, is listed on 3 filings — most recently by Starr Life Sciences Corp. (Jul 1, 2011). The two records do not overlap in time: this page runs Sep 4, 2013 to Sep 26, 2024; the other runs Oct 25, 2010 to Jul 1, 2011.

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.

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).
