Investment thesis
Hallstone Ventures invests in the industry-specific AI infrastructure layer for media, entertainment, and advertising — deliberately positioning itself as an infrastructure fund rather than a content or media fund. The firm argues that while most AI venture capital has concentrated on foundational layers like chips, model labs, and hyperscalers, the infrastructure layer serving media and advertising remains underfunded, leaving early-stage opportunities at sub-$10M valuations with real revenue and identifiable buyers. Its edge comes from a working LP network of about 70 senior operators who support diligence, open buyer conversations, and accelerate pilots. The fund explicitly avoids content slates, IP/royalty speculation, low-margin services, and LLM wrappers lacking proprietary data or workflow moats.
