Mirage, the startup behind AI video editing app Captions, has raised 75M USD in funding from General Catalyst. The company rebranded from Captions to Mirage last year to position itself as an AI lab creating models for advertising and marketing. It has trained a specialized model for video pacing, framing and attention dynamics, and recently launched an audio model that preserves user accents in generated videos. The app has been downloaded 3.2M times in the past year with 28.4M USD in revenue, and over 200M videos have been created on the platform. https://techcrunch.com/2026/03/24/mirage-raises-75m-to-continue-building-models-for-its-ai-video-editing-app-captions/ #AIagent #AI #GenAI #AgenticAI #Mirage
