Built for founders who know the stack.
If you are building AI infrastructure for media, entertainment, or advertising, we want to hear from you. Hallstone was built by operators to back operators.
What We Look For
Founder insight
Domain experience that gives you a distinctive understanding of the problem and the ability to build through change.
A real buyer
A named budget owner, a clear adoption path, and a product that fits how customers already work.
Durable infrastructure
Defensible workflow integration or proprietary data, with manageable IP, rights, and consent risk.
Room to scale
A credible path to software margins and a venture-scale market, with a clear view of unit economics.
How We Can Help
Approximately 70 domain-expert LPs, including studio, agency, and big tech CTOs and technology leaders, bring operating experience from across the media stack.
Operator Perspective
We match founder needs with relevant LP expertise to pressure-test workflows, product choices, and adoption barriers.
Relevant Introductions
Connections to potential buyers, partners, and domain experts where there is mutual fit.
Buyer-Led Feedback
Practical questions about budgets, integration, and customer value, informed by people who have bought and built these systems.
Our Process
Origin Story
First call is about you, not the deck. We want to understand how you got here, what you’ve learned that others haven’t, and why you are the person to build this.
Deep Dive
If there is mutual fit, we go deep: product, buyer, workflow integration, unit economics, data posture, competitive landscape.
Partner Decision
Investment decisions are made by the partners with input from our LP network where relevant. We give direct feedback on fit and next steps.
Building in our focus areas?
Looking for operator perspective rather than investment review? Our Expert Matching Program is a separate pathway for practical support.
