The filing says the first sale was Jun 26, 2015. The Form D was filed Jul 16, 2015 — 20 days later. The rule: a Form D is generally due within 15 days after the first sale, so this one is 5 days past that.

The latest filing for this offering is dated Aug 23, 2016 (first sale Jun 26, 2015). It reports $17,968,672 sold of $60,000,000 offered. No later amendment is in our index as of Oct 24, 2026.

The latest filing for this offering is dated Jan 7, 2015 (first sale Oct 31, 2014). It reports $20,662,495 sold of $24,999,999 offered. No later amendment is in our index as of Oct 24, 2026.

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.
