Cast Insights converts spoken audio from television, radio, podcasts and livestreams into a permanent, queryable intelligence layer that tracks who is speaking, what is said, when it occurs, and how narratives and sentiment evolve. The platform emphasizes real-time features such as alerts within thirty seconds of broadcast, speaker-level voice tracking, and narrative curves across thousands of sources. Founded in 2025 and based in San Francisco, the company has gathered more than 2.3 million hours of speech data from over 20 countries and 10 languages. Cast Insights plans to scale to 20 million hours processed and 500,000 hours of live content monitored daily to build a large American ephemeral speech dataset. The product is offered to institutional clients including hedge funds, policy teams, corporate strategy groups, and newsrooms. The company is backed by investors including Abstract Ventures, Village Global, HF0, Max Ventures, and Founder Embassy.
