In the Room
Hallstone connects founders, operators, and domain experts who are building and buying the AI infrastructure layer of modern media and advertising.
A Bright Future, In the Room
On June 4, 2026, Hallstone brought together our LP community, portfolio founders, and the operators and executives shaping the future of media, entertainment, advertising, and technology.
The night was meaningful because it reflected what Hallstone is trying to build: a working community of people who understand this sector deeply and are willing to help founders navigate it.
For founders, that matters. Capital is important, but in a market where workflows, buyers, rights, monetization, and adoption paths are all changing at once, context matters too. The right network can help validate product direction, open relevant conversations, and make the path from idea to adoption more practical.
This short video captures the spirit of that evening and the community forming around Hallstone Fund I.
