From Form ADV filed by J2 VENTURES ADVISORS, LLC CRD 317140 ↗, latest filing March 2026, covering 6 funds linked to this firm by Form D file number. Form ADV is filed once a year, so a provider may have changed since. How this is matched.
What this is. Every figure on this page comes from Form D filings with the U.S. Securities and Exchange Commission — public records, reproduced here as filed. Service providers, where shown, come from the adviser’s Form ADV and are dated.
What it is not. Single-deal SPVs, feeder vehicles and GP or employee commitment funds are listed but excluded from fund counts and capital totals: an SPV is one investment, a feeder holds the same capital as its master, and a “Principals” or “Entrepreneurs” fund closes alongside a main fund rather than being raised in its own right. Capital deployed from a family office, a corporate balance sheet or an evergreen structure never arrives as a fund close, so a firm doing that looks quiet here. Amounts are as of the last amendment and go stale. Dates are the date of first sale — a fund's first close, not its final one. Funds filed as “Indefinite” are excluded from totals rather than counted as zero, so a total is a floor.
“No recent fund” is a statement about filings. It is not a statement about whether a firm is solvent, investing, or still in business.
