Video: I built an autonomous AI agent to find startup ideas (Python+Pydantic)

Hi HN, OP here.

I recently shared the text write-up of my autonomous market research agent. Based on the questions I got about the specific implementation, I recorded a video walkthrough of the architecture and codebase.

In the video, I show:

The Pydantic AI orchestration logic.

The state-based pipeline architecture using Postgres/pgvector.

Two bugs I ran into with Gemini Flash, e.g. how I prevented it from truncating UUIDs.

A demo of the new Audio Overview feature (generating a podcast from the research).

Happy to answer any questions about the stack!
