Gaingels Feather LLC

With no prior filings attributed to this manager, this represents Grossinger's first registered vehicle, meaning allocators cannot evaluate a track record across vintages or assess how strategy, fees, or LP terms have evolved—this is a founder-stage manager establishing infrastructure for what may become a repeatable fund series.

A June 2026 filing in an Other fund type under Reg D 506(b)—restricted to pre-existing relationships—indicates the GP is building a closed network raise rather than testing public market appetite, a timing choice that signals confidence in existing LP relationships or a deliberate strategy to operate outside the larger GP fundraising cycle.

Before committing, LPs should confirm whether Grossinger has prior fund management experience outside of EDGAR visibility (e.g., secondary vehicles, SPVs, or advisory roles), as the absence of a filing history does not confirm this is his first institutional capital deployment—clarifying prior fund experience, auditor appointment, and key-man insurance provisions is critical for first-time vehicles.
