We’re a team of artists, engineers, and researchers building controllable AI video editing tools to unbound human creative potential. Our research team builds AI video models to understand and affect fine-grained, controllable edits on any human in any video.

Our product team makes these models accessible to everyone from everyday people, professional editors and animators, developers, and businesses large or small to reach new audiences and tell outstanding stories.

Our technology is used to automate lip-dubbing in localization processes in entertainment, create dynamic marketing campaigns personalized to individuals or communities, animate new characters to life in minutes instead of days, fix mistakes in post-production by making word-level edits to avoid rerecording entire scenes, and more – this is just the beginning.

In the last 12 months we graduated at the top of our YC batch (W24), raised a $5.5M seed backed by GV, won the AI grant from Nat Friedman and Daniel Gross, scaled to millions in revenue – and we're only just getting started.
