We're building the future of storytelling and video editing.
We're a small team that moves fast and builds things we're proud of.
We care obsessively about taste: in design, in product, in every detail.
We're solving these hard problems.
We're backed by a Tier-1 global fund, YC, and founders of billion dollar companies.
What We Do
Cardboard, Inc. develops an agentic, browser-based AI video editor for growth and marketing teams and serious creators. Users can describe an intended edit in natural language, while the product cuts, captions, reframes, composes, and searches footage. Its browser-native workflow combines a multi-layer timeline, collaboration, auto-captioning, voiceover and music generation, and exports for professional finishing applications, helping teams produce and iterate videos faster.
