Proteus Series Feeder Fund IV, LLC - Specialized Fund I

The five-GP team and absence of any prior EDGAR filings indicates this manager either operates outside SEC filing thresholds (managing under $150M across all vehicles) or is new to registered fund management; the feeder IV designation contradicts the 'no prior EDGAR history' signal, suggesting either a name change, a new entity structure, or prior vintages held in private placement documentation not surfaced in a standard EDGAR search.

Filing an amendment in May 2026 during a reset in LP dry powder allocation and mid-market GP fundraising activity points to either a mid-raise adjustment responding to LP feedback, a capital reallocation within an existing commitment, or a correction to the initial filing—the $1M target is unusually small for a formal feeder vehicle, raising questions about whether this is a true minimum or a placeholder pending a material increase.

Before committing, verify whether this feeder's master fund is identified in side documents and whether the five named GPs carry key-man provisions individually or as a collective—also confirm whether prior feeder vintages (I, II, III) exist in alternate filing systems or under different entity names, as the amendment status suggests an evolving structure that may not be fully transparent in public records.
