Dosign Inc. is a media-tech startup that develops and operates nullz Video Agent, a browser-based AI video-editing automation agent. Led by a founder with 11 years of media field experience, the company is built on a solid business base — 536 B2B video projects, 77 partners, an 87.5% repurchase rate, and two consecutive years of operating profit. An AI agent automatically edits real, filmed footage into broadcast-quality finished videos, used directly in the browser with no installation or high-end hardware. Rather than a text-to-video generator, it is editing automation that keeps real footage intact — preserving real people and their speech without synthesis to protect content trust. Backed by a 6,450-entry editing-grammar dataset, a multi-agent pipeline, a proprietary rendering engine, and 1 granted plus 4 pending patents, Dosign is expanding its market through B2B2C collaborations with companies at home and abroad.
