Investment thesis

Hallstone Ventures backs seed-stage founders building the AI-driven software and infrastructure layer for the media and attention economy. Its focus areas include creator infrastructure (tools, platforms, and workflows for creators and media businesses), adtech and monetization rails (measuring and monetizing attention), immersive and spatial media systems (virtual production, spatial computing, next-gen media), and frontier media infrastructure where the path from technology to commercial application is credible. The firm believes AI is accelerating a rebuild of the foundational infrastructure behind how media is created, distributed, measured, protected, and monetized, and it aims to back the founders building those foundational layers.
