Sonilo Raises $11M Series A Led by B Capital for Video-to-Music AI

Sonilo Secures $11M Series A

Sonilo, a San Francisco-based generative audio company, has raised an $11 million Series A round led by B Capital. Redpoint Ventures also participated in the round, which was announced on October 8, 2026.

What Sonilo Does

Sonilo builds video-to-music AI that composes original soundtracks and sound effects designed to follow a video's pacing, cuts and emotional arc. Unlike text-prompt-driven audio tools, Sonilo's models take the footage itself as input.

Licensed Training Data and Commercial Clearance

The company's models are trained on licensed catalogs. This includes what Sonilo describes as a first-of-its-kind Shutterstock partnership that pays rights holders licensing fees and a revenue share. As a result, every output is cleared for commercial use — a meaningful differentiator for buyers evaluating IP risk in generative audio.

Who It Serves

Sonilo's platform targets three customer segments:

• Creators — individual and team-based video producers seeking original, rights-cleared audio.
• Developer platforms — accessed through an API, including a ComfyUI node and a fal partnership.
• Enterprise production teams — organizations with ongoing soundtrack and sound-effect needs.

Round Details

• Company: Sonilo
• Round type: Series A

• Announced: October 8, 2026
• Lead investor: B Capital
• Participating investors: Redpoint Ventures
• Stage: Series A

Acquisition Context

The round gives Sonilo fresh capital at the Series A stage. For strategic acquirers, the company's combination of video-native audio generation, licensed training data and an API distribution channel through developer tooling (ComfyUI, fal) represents a position in the generative audio stack where IP clearance and platform integrations are both relevant. The participation of Redpoint Ventures alongside lead B Capital provides a two-investor syndicate at this stage.

Sonilo's stated commercial-use clearance and its Shutterstock licensing arrangement are the company's own descriptions of its model training and rights structure. No customer names, revenue figures or valuation were disclosed in the funding information.
