The short version

Jonathan Klein is listed as an executive officer and director on 9 SEC Form D filings by 6 issuers between Jun 2009 and Nov 2023. Largest by amount reported sold: Griffey Investors, L.P. (New York, NY — industry reported as "Other" — 2012; $1B reported sold to 47 investors), Squarespace, Inc. (New York, NY — other technology — 2010–2021; $190M reported sold to 27 investors), ETSY INC (Brooklyn, NY — other technology — 2012–2014; $40M reported sold to 31 investors), Hang Media Inc. (Mt. Kisco, NY — other technology — 2023; $9.21M reported sold), Helix Sleep, Inc. (New York, NY — retailing — 2016; $8.27M reported sold to 29 investors) and 1 more (all listed below).

What this means A repeat sponsor — 6 separate companies raised money with this person listed as executive officer and director, over about 14 years. Across those companies the filings report $1.25B sold in total.

Listed alongside Andrew Braccia (3 shared filings), Anthony Casalena (3 shared filings), Anton Levy (2 shared filings), Caterina Fake (2 shared filings), Daniel Rimer (2 shared filings) and 37 others.

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

1 of the issuers belongs to the sponsor group Griffey (2 issuers, $1.21B reported sold, 2012–2015).

What this means A sponsor group is one team that sets up a new company for each deal. Griffey has 2 companies on file and $1.21B 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) — 12 bankruptcy cases matching the name listed in Key records below.

What this means 12 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 9 public filings for Jonathan Klein and found 6 differences, 1 worth asking the sponsor about: Form D filed 148 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

6 differences found between the filings for Jonathan Klein — 1 worth asking about (compared 9 filings on Oct 24, 2026)

Worth asking · Apr 4, 2016 – Aug 30, 2016

Form D filed 148 days after the first sale — Helix Sleep, Inc.

The filing says the first sale was Apr 4, 2016. The Form D was filed Aug 30, 2016 — 148 days later. The rule: a Form D is generally due within 15 days after the first sale, so this one is 133 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 · Sep 21, 2023 – Nov 17, 2023

Form D filed 57 days after the first sale — Hang Media Inc.

The filing says the first sale was Sep 21, 2023. The Form D was filed Nov 17, 2023 — 57 days later. The rule: a Form D is generally due within 15 days after the first sale, so this one is 42 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 · Jul 2, 2010 – Jul 19, 2010

Form D filed 17 days after the first sale — Squarespace, Inc.

The filing says the first sale was Jul 2, 2010. The Form D was filed Jul 19, 2010 — 17 days later. The rule: a Form D is generally due within 15 days after the first sale, so this one is 2 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 · Oct 18, 2012 – Oct 26, 2012

No amendment in the last 12 months on an offering that may still be open — Griffey Investors, L.P. (latest filing Oct 26, 2012)

The latest filing for this offering is dated Oct 26, 2012 (first sale Oct 18, 2012). It reports $1,000,000,000 sold of an indefinite amount 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 · May 10, 2012 – May 14, 2014

Industry group changed between filings — ETSY INC

"Other" (May 10, 2012); then "Other Technology" (May 14, 2014).

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.

Sources
Note · Dec 30, 2020

Same name, different state: "JONATHAN KLEIN" (CA) is a separate record

This page covers filings where the address state is NY. A separate record, "JONATHAN KLEIN" with address state CA, is listed on 1 filing — most recently by National Realty Trust Inc. (Dec 30, 2020). Both records have filings in the same period (Dec 30, 2020).

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
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).
