East Rock Granite Fund, L.P.

No prior EDGAR filings from this manager signal either a first-time fund launch or an established operator who has structured vehicles outside the SEC's filing requirements until now; the single-GP structure and absence of co-GP or co-investment vehicle filings suggest Shapiro is running this independently rather than within a larger platform or partnership.

Filing an amendment in May 2026 on a placeholder vehicle points to either a delayed launch (original intent may have been earlier) or a reset of terms and LP commitment windows; the revision timing aligns with mid-year LP capital allocation cycles when some allocators commit Q2 reserves, though the placeholder status means actual deployment is still uncertain.

Before engaging, verify whether this amendment revised key economics—management fee, carry, or fund life—from the initial placeholder, and confirm whether Shapiro has side letters or separately capitalized co-investment pools that would sit outside this fund's main LP base; also establish whether there is a binding key-man clause or removal trigger tied solely to Shapiro.
