Sonilo Raises $11M for Video-to-Music AI Amid Audio Megarounds

What happened

Sonilo, a San Francisco generative audio startup founded by former members of TikTok's AI and music teams, has raised $11 million. B Capital led the round and Redpoint also participated. 5 The company is building models that compose music and sound effects to match what happens on screen. Executives say the new capital will mainly cover the compute needed to scale those models. Sonilo also plans to expand its reach among creators and developer platforms and to grow a music licensing business. 5

Sonilo describes its technology as a proprietary multimodal system that ties together video understanding, audio generation and temporal alignment. In plain terms, it is meant to read a clip's pacing, mood and storyline, then produce a soundtrack that fits convincingly. 1 CEO and co-founder Shawn Song presents the core difference as starting from footage instead of a text prompt. The system analyzes the video frame by frame before generating anything. 1

The licensing angle

The raise follows a partnership announced in May, when Sonilo licensed Shutterstock's music catalog for AI model training. 2 Shutterstock called it its first deal with a video-to-music AI platform. Sonilo, in turn, bills itself as the first professionally licensed product in that category. 2 Those "first" claims come from the company's own announcement and should be read that way. Still, the strategy is clear. Sonilo is positioning itself as the clean-rights option in a sector where questions about training data have shadowed nearly every major player.

The deal also helps explain why licensing appears among the uses for the new funding. 5 A startup that has secured rights to its training data can pitch brands, agencies and platforms that are wary of legal exposure. That is a different sales motion from the consumer-first approach of the category's best-known names.

Why $11M looks small, and why that may not matter

Next to recent AI audio financings, Sonilo's round is modest. Suno, the generative music platform, raised $400 million in a Series D at a $5.4 billion valuation. That came roughly six months after a $250 million raise. 3 Bond Capital led Suno's round, with participation from a long list of returning and new investors. 3 In voice, ElevenLabs recently raised $500 million at an $11 billion valuation. 4 Even an early-stage challenger like Fish Audio, which began as a weekend side project, closed a $52 million seed round with the aim of making voice the default interface for AI models. 4

Those figures show how much capital is flowing into AI audio, and how unevenly it is distributed. The pattern resembles the wider AI market. A few category leaders absorb enormous late-stage checks, while specialists raise far smaller sums to prove out narrower products.

Sonilo falls clearly in the second group. Its pitch is not to be a general music generator competing with Suno on every front. It aims at a specific workflow: scoring video that already exists. That is a defensible niche to aim for. Short-form creators, ad producers and app developers all need soundtracks timed to visuals, and text-prompted tools do not naturally provide that timing. The founders' TikTok background is relevant here, since the problem they are tackling is one that short-video platforms face at enormous scale. 15

Divergent paths to the same market

The companies in this space are chasing different routes to commercial viability. Suno says it will use its new money to build better models and expand its platform. 3 Fish Audio has moved beyond its early base of game developers and content creators into regulated sectors such as healthcare and financial services. It offers on-premises deployments with zero data retention and HIPAA compliance. 4 Sonilo, for its part, is betting that licensed training data combined with video-first generation will win over customers who care about provenance. 25

There is a common thread. As these models get better, raw output quality is no longer enough to stand out. Trust, compliance and integration into existing workflows are becoming the real competitive levers.

The takeaway

Sonilo's $11 million is not a megaround, and it won't change the balance of power in AI audio. But measuring it only against Suno or ElevenLabs misses the point. The round funds a focused test of whether a rights-cleared, video-native scoring tool can carve out its own lane. If buyers increasingly demand licensed AI output, a small, targeted bet could age better than its headline number suggests. The main risk is that larger, better-funded rivals add credible video-to-music features of their own before Sonilo builds enough scale to defend its position.
