Hey 👋 I’m Rohan, founder of Serafis — a search and discovery engine for long-form content, starting with podcasts.

TL;DR our library features >10,000 curated transcripts featuring top investors, Series A+ founders, and public company CEOs — searchable by person, company or theme. We’re already live with 5 organizations managing over $40B in capital.

Serafis turns under-indexed data into structured market intelligence, helping investors:

• Accelerate research

• Surface new insights

• Distill signal from noise

🤯  The problem: we live in an age of information overload.

Smart, credible people — from AI researchers to CEOs of $100B+ companies — are on hundreds of hours of podcasts every week. How do you know what’s relevant and worth your time?

🚀  The solution

Serafis enables smart discovery and accelerates research

  • View our pre-computed analysis & data points. Run custom queries.
  • Filter content by credibility, information density and non-consensus ideas.
  • Search by person, company or theme — then hone in using relevance scores.

📈  Podcasts are just the starting point. We’ll soon be indexing select content on YouTube, blogs and more.

💼  Who it’s for

  • Anyone doing thematic research, especially: institutional investors, wealth advisors or people in corporate strategy.
  • Possibly you! If you find podcasts to be a valuable source of information 🙂.
