Problem

Video editing remains a labor-intensive bottleneck for creators, marketers, agencies, podcasters, and media organizations. Traditional editors bury routine tasks behind menus and controls, while AI copilots often provide only partial assistance; Mosaic frames the economic pain as editing work that can consume hours for each asset. Its main use case is high-volume content production: turning one piece of raw footage into many polished clips, formats, and variants without requiring an editor to repeat the same manual operations.

Product / Service

Mosaic is a software platform for agentic AI video editing, centered on Canvas, a node-based workspace where users assemble reusable multimodal editing agents. A workflow starts with media input, applies creation or action tiles such as captions, reframing, trimming, color correction, avatars, voiceovers, or generated media, and produces an output automatically. The system is intended to get users most of the way to a finished edit on autopilot, after which they can refine the result in a familiar timeline editor.

The product is delivered as a self-serve subscription with Creator and Pro plans, an enterprise tier with custom pricing, and API access for programmatic editing. It supports triggers and integrations involving services such as YouTube, Google Drive, Slack, Mimir, Iconik, Premiere, DaVinci Resolve, and other workflow tools, allowing agencies and media teams to automate recurring production pipelines rather than merely edit individual videos.

Market

Mosaic competes in agentic AI video editing and video-workflow automation. Its closest AI-oriented alternatives include OpusClip and Klap, while traditional non-linear editors such as Adobe Premiere Pro and DaVinci Resolve are important adjacent platforms. Mosaic differentiates itself by combining AI editing agents, repeatable workflow automation, brand-specific rules, integrations, and final human control instead of positioning AI as only a chat layer on top of a conventional timeline.

The company appears to be commercially launched rather than pre-revenue: its site lists paid Creator and Pro subscriptions plus custom enterprise pricing, claims more than 1,000 marketers, agencies, and creators, and names customers or users including The Sun, talkSPORT, TubeScience, and News Corp. Mosaic was founded in 2024, joined Y Combinator’s Winter 2025 batch, and announced a $3.8 million seed round in April 2026; it says global agencies, platforms, podcasters, and news networks use its workflows to scale content production.
