Sonilo Raises $11M to Expand Audio Generation
Sonilo raised $11M led by B Capital to expand its AI model infrastructure and music licensing operations.

The big picture: San Francisco-based generative audio technology company Sonilo has raised $11 million in funding. B Capital led the round, with participation from Redpoint. The investment will support the expansion of Sonilo’s AI model infrastructure, development of distribution partnerships, and growth of its music licensing operations.
Why it matters:
- Automated Audio: Sonilo’s technology aims to automate significant portions of the audio production process for content creators, developers, and media companies, reducing manual effort in selecting music, editing sound effects, and synchronizing audio with video.
- Video-Driven Generation: Unlike most audio generation tools that start with text prompts, Sonilo’s Sound World Model analyzes visual content, including movement, timing, and scene transitions, to generate contextually relevant music and sound effects.
- Licensing Framework: The company is developing a licensing framework for its AI training data, including partnerships with entities like Shutterstock and ongoing agreements with major music rights organizations, addressing a key industry concern in generative AI.
How it works:
- Sound World Model: Sonilo’s core technology integrates video analysis, audio generation, and synchronization capabilities to understand a video’s visual story frame by frame, including pacing, emotion, and narrative.
- Multimodal Input: Users can generate audio by uploading video footage, providing written instructions, or combining both methods, allowing for flexible creative control over the output.
- AI Dubbing: The platform also offers AI dubbing with synchronized lip movements, enabling production teams to efficiently adapt video content for different languages and global audiences.
The catch: The generative AI audio market is becoming increasingly competitive, with numerous startups and established players vying for market share. Sonilo’s success will depend on its ability to differentiate its video-driven approach, secure robust music licensing agreements, and demonstrate superior audio quality and seamless integration into existing production workflows amidst evolving industry standards and copyright debates.
