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.

1 of the issuers belongs to the sponsor group Frost (13 issuers, $102.5M reported sold, 2009–2020).

What this means A sponsor group is one team that sets up a new company for each deal. Frost has 13 companies on file and $102.5M 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 (AZ, CA, DE, TX, WA) — 3 court cases matching the name, 2 bankruptcy cases matching the name listed in Key records below.

What this means 5 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 8 public filings for Michael Eisenberg and found 11 differences, 3 worth asking the sponsor about: Amount sold went down between filings; Investor count went down between filings; 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

11 differences found between the filings for Michael Eisenberg — 3 worth asking about (compared 8 filings on Oct 24, 2026)

Worth asking · Jun 30, 2009

Amount sold went down between filings — Gigya, Inc.

The Jun 30, 2009 filing says $8,606,884 sold; the Jun 30, 2009 Form D says $1,020,003 sold — $7,586,881 less.

What this means Amounts sold normally only go up as a raise continues. A drop can mean investors were refunded, a figure was corrected, or an earlier number was wrong. Ask the sponsor which it was.

Sources
Worth asking · Jun 30, 2009

Investor count went down between filings — Gigya, Inc.

The Jun 30, 2009 filing reports 4 investors; the Jun 30, 2009 Form D reports 2 investors.

What this means Investor counts normally only grow. A smaller number can mean investors left or were refunded, or a count was corrected. Ask the sponsor what happened.

Sources
Worth asking · Dec 14, 2006 – Sep 12, 2012

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

Form D filed 133 days after the first sale — Gigya, Inc. · Form D filed 284 days after the first sale — Gigya, Inc. · Form D filed 480 days after the first sale — Gigya, Inc. · Form D filed 480 days after the first sale — Gigya, Inc. · Form D filed 842 days after the first sale — Gigya, Inc. · and 3 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 · Jun 30, 2009

4 offerings changed their target amount between filings

Offering amount changed between filings — Gigya, Inc. · Offering amount changed between filings — Gigya, Inc. · Offering amount lowered between filings — Gigya, Inc. · Offering amount changed between filings — Gigya, Inc.

What this means Targets change as deals grow or shrink. Ask whether later money has the same terms.

Sources
Note · May 2, 2012 – Sep 12, 2012

No amendment in the last 12 months on an offering that may still be open — Gigya, Inc. (latest filing Sep 12, 2012)

The latest filing for this offering is dated Sep 12, 2012 (first sale May 2, 2012). It reports $15,346,574 sold of $15,846,569 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 · Feb 2, 2011 – Mar 7, 2011

No amendment in the last 12 months on an offering that may still be open — Gigya, Inc. (latest filing Mar 7, 2011)

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 · Jun 30, 2009 – Sep 12, 2012

Industry group changed between filings — Gigya, Inc.

"Other Technology" (Jun 30, 2009 to Mar 7, 2011); then "Other" (Sep 12, 2012).

What this means The issuer described its business differently on different forms. Often it is just a different box ticked; sometimes the deal itself changed. Ask which business your money is in.

Note · Jun 30, 2009 – Mar 7, 2011

Address moved from Palo Alto, CA to Mountain View, CA — Gigya, Inc.

The people listed on the Jun 30, 2009 filing give Palo Alto, CA; on the Mar 7, 2011 filing they give Mountain View, 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.
