Koyal Raises Seed Funding to Expand AI-Powered Filmmaking Platform

Koyal, an agentic AI filmmaking platform that transforms audio into visually compelling, personalized video narratives, has raised early capital to accelerate its development and growth after being selected into Y Combinator’s Fall 2025 batch. The San Francisco-based startup, founded in 2025 by siblings Gauri Agarwal and Mehul Agarwal — graduates of MIT and Carnegie Mellon University with experience at Meta — is building tools that enable creators, musicians, and storytellers to turn scripts or audio into cinematic content with consistent characters and scenes using state-of-the-art AI technology.

Koyal’s initial funding comes as part of its participation in the Y Combinator Fall 2025 accelerator program, a prestigious Silicon Valley seed-stage initiative that provides startups with capital, mentorship, and access to an extensive investor network, helping them prepare for broader fundraising and product expansion.

Alongside Y Combinator’s support, Koyal has received investment from Pioneer Fund, a venture capital firm backed and operated by Y Combinator alumni that writes early checks into promising startups within the YC ecosystem. Pioneer Fund’s involvement underscores its confidence in Koyal’s mission and technology and reflects broader interest in generative AI platforms that enhance creative workflows.

The combined investment — reported to total roughly $500,000 in seed funding — will help Koyal scale its AI tooling, expand its product offerings, and deepen relationships with early customers and pilot partners. The startup’s platform builds on research presented at the NeurIPS 2024 conference and incorporates patented secure personalization protocols, including the CHARCHA engine, which ensure AI-generated video content respects consent and likeness rights for individuals featured in generated content.

Koyal’s technology has already attracted attention in music and entertainment circles. The company secured paid pilot agreements with major global music labels such as Universal Music and T‑Series, as well as production houses including Maddock Entertainment and Collective Artists Network. These early engagements have led to the release of several music videos for award-winning artists, including A R Rahman, Ricky Kej, and Shankar Mahadevan, with notable audience engagement across digital platforms.

Public demonstrations of Koyal’s platform at industry events such as the World Audio Visual & Entertainment Summit (WAVES) 2025 in Mumbai showcased its ability to generate rich, emotive video narratives from audio, highlighting its potential to democratize content creation by drastically reducing the time and cost associated with traditional production pipelines.

The funding and accelerator support are timely as Koyal also moves into a public beta release, inviting creators to experiment with its AI capabilities. Founders have positioned the platform as a tool for musicians, podcasters, brands, and storytellers to generate studio-quality videos at scale without the need for extensive editing expertise or high production budgets.

Koyal’s early success and strategic partnerships suggest growing market appetite for generative tools that bridge audio and visual media, a space increasingly populated by startups seeking to enable richer multimedia experiences with AI. With backing from both Y Combinator and Pioneer Fund, the company is poised to leverage its seed capital and network to extend its product reach, refine its algorithms, and pursue further commercial adoption beyond early pilot users.

As generative AI continues to evolve, platforms like Koyal are gaining prominence for their ability to translate creative intent into immersive content, potentially reshaping how stories are told in music, film, advertising, and interactive media. With its early funding secured and community support established, Koyal is advancing toward broader market engagement and preparing for future fundraising and growth opportunities.
