Episode notes
From Basement Hacks To Pinecone
- Jack describes building an ML search tool in pharma M&A and struggling with memory‑heavy open source vector libraries.
- That pain led him to join Pinecone to democratize vector search so others wouldn't waste months on infra work.
Communicating New Tech Is As Hard As Building It
- Early adoption was stalled because most people lacked the math and context to see vector DB value.
- Naming and messaging mattered a lot until wider AI understanding (e.g., ChatGPT) made the concept click.
Retrieval Still Beats Token Dumping
- Despite larger context windows, retrieval remains critical because it gives relevant content cheaply and reliably.
- Hybrid approaches and agentic retrieval each have tradeoffs; blending them often works best.
