Overview
Cardboard is a YC W26, San Francisco-based browser-native AI video editor that turns prompts and raw footage into first cuts for growth and marketing teams. Public evidence shows a very small, founder-led team, weekly product shipping, and direct founder support; I did not find a verified public CEO title, phone number, or detailed HR policy.
