What We Back

The media economy as a cross-section. Applications sit at the surface; foundation models are bedrock. Hallstone invests in the compressed strata between — the substrate the modern media economy grows on.

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.

“Much of the AI investment in media is pointed at the factory floor, making production faster and cheaper. Less of it is pointed at the storefront: how audiences discover what to watch, and how that attention turns into revenue. We think that side is underrated, and it shapes a lot of what we look for.”

— Seth Hallen, Founder and Managing Partner
