Sonic Space I, a Series of A Master Series, LLC

The absence of any prior EDGAR filings from this manager indicates this is either a first-time fund vehicle from these GPs collectively or a deliberate shift to a new legal entity structure; the four-GP composition suggests the sponsors are either pooling capital and expertise across previously independent practices or establishing a formalized partnership for ongoing deployment, rather than operating as a single established manager with a series history.

Filing in June 2026 positions this raise during the post-rate-cut cycle when LP dry powder is re-activating and venture allocators are rotating back into growth-stage checks after 2024–2025 caution; the placeholder structure indicates the sponsors are locking legal standing before finalizing a target, a common practice when market windows are opening but final commitments from anchor LPs are still in negotiation.

Before engagement, verify whether any of the four named GPs—particularly Black Box Ventures and Litquidity Ventures—have separately filed vehicles or operate existing funds that could compete for LP capital or present conflicts of interest, and confirm whether this filing will be amended with a disclosed target or remains a holding structure; also confirm the mechanics of GP economics and voting rights among the four sponsors, as multi-sponsor structures can create friction in follow-on decisions or secondary transactions.
