Cast Insights is built on the idea that the best way to understand the future is to first understand what is happening today. Instead of relying on traditional forecasting, the company analyzes large amounts of public conversations to identify important trends and changes as they happen.

Its platform looks for recurring patterns across society, markets, and industries, while also spotting new shifts that could lead to future disruptions. By tracking these signals in real-time, Cast Insights helps organizations make better decisions based on whats happening now rather than guessing what comes next.

Cast Insights uses AI to collect spoken audio from thousands of sources around the world and turn it into real-time intelligence. The platform captures what the company calls "ephemeral speech data"—spoken information that is constantly being created and quickly disappears.

Instead of only converting speech into text, the platform also analyzes who is speaking, what they are saying, when they say it, and how opinions, and narratives change over time. This creates a searchable record of information that would otherwise be lost.

The platform is designed for investors, policymakers, business strategists, and news organizations. It helps them discover important insights from global conversations as they happen, making real time information easier to find and act on.

"We've always had this strange cultural obsession with forecasting the future, when the real problem is that we barely understand the present," said Otávio Costa Miranda, CEO and Co-Founder of Cast Insights. "Most of what gets said in the world every day across radio stations, legislatures, podcasts, and local broadcasts is ephemeral by nature. It surfaces publicly, it influences people, and then it vanishes. We call this ephemeral speech data, and it's the largest uncaptured dataset in the world.

"When we first met Otto and the team, we had this moment that keeps happening with the best founders we back, we thought, 'Wait, that doesn't exist yet? How does that not exist?'" said Evan Stites-Clayton from HF0. "Once Otto showed us the platform's features like real-time alerts within thirty seconds of broadcast, speaker-level voice tracking, and narrative curves across thousands of sources.
