START: Saksham Aggarwal, CEO & Founder, Cardboard "Agentic video editor"

Creating video is getting easier. Finishing it isn't.

AI writes code and you still review it before it ships. AI makes clips now, and someone still has to assemble them into something you'd actually publish. That's the layer cofounders Saksham and Ishan are building at Cardboard.

Two engineers who met in school and taught themselves filmmaking in Bangalore by studying Apple's launch films. Saksham describes Cardboard simply: it's Cursor for video editing.

There's no good VS Code for video, so they're building one. You throw your clips in and give it a goal, and it hands back a first cut in minutes. Brief it the way you'd brief a junior editor.

Video isn't one problem, which is what makes the editor core hard. Screen recordings need different ML pipelines than talking heads or sports footage, so a routing model decides where each query goes.

They don't want to be an AI feature inside the existing editor. They want to build the editor itself.
