Co-founder & CEO, Hidden Door · New York
I build beautiful things at the edge of what’s technically possible.
I’m Hilary Mason. These days I’m co-founder and CEO of Hidden Door, where we’re teaching machines to tell stories. I speak and advise on building AI products that survive contact with reality.
