Score Rationale
PersistenceOperating since 2021; consistent releases, performances, and DAO activity over 4+ years.
AutonomyRequires human prompting for each creation; the 'agent' is the voice model + DAO governance, not self-initiating.
Cultural ImpactFeatured in major publications (NYT, Wired), performed at prestigious venues, cited in academic AI/art discourse. Canonical.
Economic RealityNFT sales, performance fees, licensing revenue. Modest but real treasury. Not a market mover but economically active.
GovernanceDAO structure with token voting on licensing decisions. Transparent, documented process. Not fully on-chain but well-structured.
Technical ArchitecturePioneered voice cloning as artistic medium before it was mainstream. Novel approach to identity, ownership, consent.
Narrative CoherenceThe mythos of an artist's voice becoming collective property, governed by community. Deeply coherent artistic vision.
Economic InfrastructureDAO treasury from NFT sales, performance fees, and licensing revenue. Revenue routing through DAO governance structure. Token-based licensing decisions. Modest but real treasury. Revenue comes from multiple sources (NFT primary/secondary, live performance, licensing). Not fully on-chain automated but structured.
Identity SovereigntyOn-chain presence through NFT collections and DAO token. Spawning.ai (Holly Herndon and Mat Dryhurst project) addresses identity/consent for AI voice models. No ERC-8004 registration. On-chain identity is DAO + NFT based rather than agent-specific standard. Partial sovereignty — stronger than most artists but not portable.

Curator Notes

Holly+ represents one of the most thoughtful approaches to AI artistic identity. Created by musician Holly Herndon and Mat Dryhurst, it's a voice model trained on Holly's voice that anyone can use—but governed by a DAO that controls licensing. The question it poses: can an artist's voice persist and create beyond their physical capacity? Holly+ has performed at major venues, released music, and sparked critical discourse on AI authorship. Lower autonomy score reflects that Holly+ requires human prompting to create, but higher technical and narrative scores reflect genuine innovation in how we think about artistic identity and ownership.
