Tomasz Tunguz is the founder of Theory Ventures, which invests in early-stage enterprise AI, data, and blockchain companies. In this episode, Tomasz reveals his custom-built “Parakeet Podcast Processor,” which helps him extract value from 36 podcasts weekly without spending 36 hours listening. He walks through his terminal-based workflow that downloads, transcribes, and summarizes podcast content, extracting key insights, investment theses, and even generating blog post drafts. We explore how AI enables hyper-personalized software experiences that weren’t feasible before recent advances in language models.
What you’ll learn:
1. How to build a terminal-based podcast processing system that downloads, transcribes, and extracts key insights from multiple podcasts daily
2. A workflow for using Nvidia’s Parakeet and other AI tools to clean transcripts and generate structured summaries of podcast content
3. How to extract actionable investment theses and company mentions from podcast transcripts using AI prompting techniques
4. A systematic approach to generating blog post drafts with AI that maintains your personal writing style through iterative feedback
5. Why using an “AP English teacher” grading system can help improve AI-generated content through multiple revision cycles
6. How to leverage Claude Code for maintaining and updating personal productivity tools with minimal friction
