Grinich Investments
Grinich Investments last closed a fund in November 2021 — 60 months ago.
2 funds on record — a rhythm needs three. No month is guessed; the filing will say.
Late-cycle This firm is deep enough into its last fund that a new one would not be a surprise.
Still filing with the SEC: December 2025. That is an amendment to an existing offering, not a new fund - which is what an evergreen structure looks like in this data.

From Form ADV filed by PLATFORM ADVISOR, LLC CRD 167700 ↗, latest filing June 2026, covering 24 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.
