Hallstone Ventures

AI infrastructure for the attention economy.

Hallstone Ventures backs seed-stage founders building the software and infrastructure layer powering how modern media is created, distributed, measured, monetized, and experienced.

What We Back

Creator Infrastructure

Tools, platforms, and workflows for creators and media businesses.

AdTech & Monetization Rails

Technologies improving how attention is measured, packaged, and monetized.

Immersive & Spatial Media Systems

Infrastructure for virtual production, spatial computing, and next-gen media.

Frontier Media Infrastructure

Emerging infrastructure where the path from technology to commercial application is credible.

The Hallstone Edge

Backed by ~70 senior operators and technology leaders from studios, streamers, agencies, and major platforms. They are not passive investors. They open doors, validate workflows, and help founders navigate the buyer complexity that defines media and entertainment.

“AI is accelerating a rebuild of the infrastructure behind how media is created, distributed, measured, protected, and monetized. Hallstone was formed to back the founders building those foundational layers.”
