Cardboard

Cardboard is a software company that develops an agentic, browser-based video editing platform designed specifically for growth marketing teams and serious content creators. The platform utilizes artificial intelligence to automatically generate initial video cuts from raw footage based on specific user goals, such as requesting 3 distinct ad variants or a 30-second hook. Operating on a freemium business model, the startup allows users to search video content by semantic meaning and refine edits on a collaborative timeline without relying on external production agencies. The company gained early industry visibility by launching its software application on Product Hunt and participating in the Y Combinator Winter 2026 accelerator batch. Cardboard was founded in 2025 by Saksham Aggarwal, who previously built artificial intelligence systems at Iterate AI and studied computer science at BITS Pilani, alongside co-founder Ishan Sharma.
