San Francisco-based AI audio startup Sonilo has raised $11 million in a funding round led by B Capital, with participation from Redpoint. The company was founded by former TikTok employees, including CEO Shawn Song, who led multimodal AI work at TikTok, CTO Alex Yin, and COO Keli Li, who ran TikTok's global music operation. Sonilo has developed what it calls the Sound World Model, which analyses video content frame by frame to generate matching music and sound effects. The technology reads scene movement and emotional shifts to produce synchronised audio for commercial use. The startup targets short-form video creators, developer platforms, and production teams. It has partnered with Shutterstock for music licensing and signed TapNow and ComfyUI as distribution partners. The company plans to launch its consumer app in the fourth quarter.
