Mirelo Raises $41M to Add AI-Generated Sound to Silent Video Content

Mirelo, a startup focused on enhancing video content with AI-generated audio, has secured a $41 million seed round led by Index Ventures and Andreessen Horowitz. The investment aims to solve the “silent problem” that plagues AI-generated and edited videos, where missing audio diminishes immersion and impact.

Key Takeaway

Mirelo’s technology automatically generates and synchronizes missing sound effects with video content, aligning with visual cues, rhythm, and context.

Product & Technology

The company is developing algorithms that detect gaps in audio tracks and produce realistic sounds that match the video’s pacing and scene dynamics. This fully automated, video-centric approach differentiates it from other AI‑audio tools such as Descript, Adobe Audition, and DeepVoice.

Funding & Strategic Vision

The $41 million seed round, led by Index Ventures and Andreessen Horowitz, provides the resources to push the beta release in Q1 2026 and launch a commercial API for developers, studios, and content creators.

Market & Growth

Target customers include content creators, advertising agencies, film studios, short‑video platforms (TikTok, Instagram), and game developers. By monetizing through API subscriptions, licensing, and platform integrations, Mirelo aims to capture significant market share in the evolving video‑content ecosystem.
