SPV 426, a series of Harris Austin, LP

Jonathan Wasserstrum is the sole named GP on record across all EDGAR filings, and the absence of any prior Harris Austin fund history suggests either a new manager entering EDGAR-filing territory for the first time or a known operator launching their first documented venture vehicle—either way, this is the baseline filing for LP due diligence on this manager's formal track record.

A May 2026 filing in a rising-rate environment when LP dry powder for micro-cap venture remains constrained signals either a specific commitment cycle with an existing syndicate or a response to sector-specific opportunity in the pre-seed/seed stage where $1M check sizes are modal.

Verify whether Jonathan Wasserstrum has key-person provisions tied to his continued involvement, and confirm whether Harris Austin, LP itself has any GP-affiliate relationships or prior fund vehicles registered under alternative names or structures—a manager's first EDGAR filing merits cross-checking for historical fund vehicles operated outside this naming convention.
