Sonilo Secures $11M Seed Funding to Enhance AI Audio Capabilities for Video Production

Sonilo, a San Francisco-based startup, has successfully raised $11M in a Seed funding round led by B Capital, with participation from Redpoint. The company specializes in developing AI-generated music and sound effects tailored to video content, leveraging its unique Sound World Model technology. This innovative approach allows users to generate sound that complements video footage, enhancing the overall production experience.

The funding announcement was made on October 8, 2026, with the capital aimed at scaling Sonilo’s operations in several key areas. Specifically, the funds will be allocated toward increasing computing capacity, expanding distribution to creator and developer platforms, and establishing deeper relationships with music rights holders. This strategic focus reflects the company’s commitment to integrating AI audio seamlessly into video workflows, making it easier for creators to access high-quality sound tailored to their specific needs.

Sonilo’s leadership team boasts significant experience in the tech industry, with CEO and co-founder Shawn Song and CTO Alex Yin having backgrounds in TikTok’s multimodal AI initiatives. COO Keli Li, who previously managed TikTok’s global music operations, rounds out a team well-equipped to navigate the complexities of audio licensing and production.

The competitive landscape for AI audio technology is heating up, with a growing demand for tools that simplify the video production process. By positioning itself at the intersection of video and audio, Sonilo aims to establish a strong foothold in a market that includes other startups focused on AI video workflows and music royalty infrastructure.

The recent funding will help Sonilo further develop its technology and expand its reach in the creator community. As the company prepares to launch its consumer app in the fourth quarter of 2026, it is poised to capture a significant share of the market by providing creators with tools that enhance their storytelling capabilities through sound. With the backing of prominent investors like B Capital, Sonilo is well-positioned to lead the charge in redefining how audio is integrated into video production, offering a streamlined, efficient solution for creators and developers alike.
