Researched company profiles named by domain or company name (acme-corp.md, example-io.md). Each profile contains: company overview, key products/services, leadership team, recent news/funding, and user's relationship/notes. Create when user researches a company; update when significant new information emerges (funding rounds, leadership changes). Include research date and sources for freshness tracking. Check existing profiles before new research to avoid duplicate work. Don't store raw search results—synthesize into actionable intelligence. Link to ui:research.exa.people for individuals at the company.
