A domain-specific AI product built around private data, specialized models, and purpose-built workflows
Build a focused product for a domain where general-purpose models perform poorly, combining access to information the general model cannot see with a specialized model, retrieval, memory, tools, and a carefully designed user experience.

From Y Combinator — Jeff Dean: The 1% Rule for Building in AI at 27:20
Problem: General models may lack access to private information or may perform poorly on difficult, specialized tasks that require high accuracy.
For: People or organizations working in a specialized domain whose important data or workflows are not well served by general-purpose AI models.
Examples
- A personal-information organizer: a product can have an advantage because it can access and organize a user's information that a general model cannot see.
Behind this: 12 build steps · 1 tool and how each is used · how to validate demand · 2 more real examples · 5 things the video never answers.
