Company Overview
About Mirelo
Mirelo is solving the "silent problem" in AI video generation: AI-generated videos have no synchronized, contextually appropriate sound. The company raised $41 million in seed financing led by Andreessen Horowitz and Index Ventures in December 2025, and launched SFX v1.5 and Mirelo Studio in early 2026. The platform generates synchronized sound effects, ambient audio, and music that matches the visual content of AI-generated or edited video.
Business Model & Competitive Advantage
The technical differentiation is efficiency: Mirelo's model runs 50x more compute-efficiently than typical large language models while producing audio that matches the visual rhythm, mood, and content of the input video. It is distributed through Fal.ai and Replicate APIs, allowing developers building AI video applications to integrate sound generation without building proprietary audio models.
Competitive Landscape 2025–2026
As AI video generation volume explodes in 2026 — with Runway, Luma AI, and Higgsfield collectively producing millions of clips — audio synchronization becomes a mandatory infrastructure layer. Every AI video application needs sound, and building proprietary audio generation is a significant engineering investment. Mirelo's API-first model positions it as the default audio generation layer for the AI video stack.
