Questions & Answers
What problem or opportunity inspired you to start your company, and how has your vision evolved since then?
Midway through last year, I became obsessed with the idea of taking the same video—say, a 5-10 minute clip—and personalizing it for each viewer while preserving the shared storyline. My conviction in this vision has only grown over time, but it has been refined as we’ve begun defining the core building blocks that make this experience possible, such as character swapping, face swapping, object swapping, and more.
What sets you apart from others in your industry?
Unlike existing interactive videos—such as Bandersnatch the black mirror episode or interactive livestreams—that rely on pre-defined, hard-coded branches, we enable truly dynamic, personalized video elements. Our AI video models allow users to control and modify content in real-time, generating personalized outputs instantly within a radically simple UI. What sets us apart for creators is the ease and speed of production. Our approach makes it 100x faster and more efficient to create highly engaging, interactive content—without sacrificing quality or control.
