About
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.
