Koyal
Koyal is an agentic AI filmmaking platform (Y Combinator F25) that turns a script or an audio clip - a song, a podcast, a voiceover - into a finished, personalized video with consistent characters, settings and camera work. Founded by CMU/MIT/Meta alumni siblings Mehul and Gauri Agarwal, the company follows a Pixar-style 'audio first, visuals second' approach and has run paid pilots with Universal Music, T-Series and Bollywood studios, producing music videos for artists like A.R. Rahman, Ricky Kej and Shankar Mahadevan.
Flawless
Flawless is an AI filmmaking company building assistive tools that let studios re-edit dialogue and localize films into other languages while preserving the original actor's performance. Its products TrueSync and DeepEditor use computer vision and deep learning to reshape an actor's lip movements and expressions to match new lines or dubbed dialogue, removing the disconnect of traditional dubbing and subtitles. Co-founded by filmmaker Scott Mann and tech entrepreneur Nick Lynes, Flawless positions itself as a rights-first, consent-driven alternative to generative AI in cinema, endorsed by SAG-AFTRA and used across hundreds of studio productions.
