Vector search has become a foundational technology for AI applications, enabling everything from semantic code search to contextual retrieval for large language models. However, a major challenge with vector databases has been the cost as data storage scales.
Turbopuffer is a vector database that focuses on speed, cost and scalability. It was created by Simon Hørup Eskildsen and Justin Li in 2023 and has seen adoption from high-profile companies such as Cursor and Notion.
Simon joins the podcast with Gregor Vand to discuss the origin of turbopuffer, its unique technical design, the economics of vector storage, and more.
Capital One’s tech team isn’t just talking about multi-agentic AI.
They already deployed one.
It’s called Chat Concierge, and it’s simplifying car shopping.
Using self-reflection and layered reasoning with live API checks,
It doesn’t just help buyers find a car they love.
It helps schedule a test drive, get pre-approved for financing, and estimate trade-in value.
Advanced, intuitive, and deployed: that’s how they stack.
That’s technology at Capital One.
Building agentic AI apps isn’t just about choosing the best LLM.
Agents need short‑term memory, long‑term recall, and lightning‑fast retrieval. Without it, you’re left with clunky prototypes that never scale.
You know, Redis? The world’s fastest caching solution?
It turns out fast data is the key to good context. And good context is essential for fast, accurate memory. It’s what makes AI agents actually work with your data.
Redis for AI. The right infrastructure. The right tools. The only way to scale.
