Mosaic
Agentic AI video editing platform. Build multimodal editing agents on a node-based canvas that run edits on autopilot, get reused across projects, and improve over time.
About
Mosaic is an agentic video editing platform. Its canvas lets anyone create and run multimodal video editing agents: once built, an agent can run edits on autopilot, be reused across video projects, and improve over time, compressing hours of editing work into seconds.
Founded in 2024 and part of Y Combinator's Winter 2025 batch, Mosaic is based in San Francisco. It was started by Adish Jain (CEO, previously in engineering at Tesla and AWS, and a Berkeley alum) and Kyle Wade (CTO, previously an ML researcher at UCSD and a software engineer at Tesla), and raised $3.8M to build out its video editing agents.
Mosaic was featured at SaaStr 2025 among a group of YC startups pushing the AI frontier, and an early prototype won the grand prize in Google's Gemini Kaggle competition.
