Problem

Companies lose critical institutional knowledge when experienced employees leave. Traditional documentation fails because tacit expertise — the kind that lives in people's heads — resists being written down.

Approach

Mentat uses AI-driven expert interviews to extract tacit knowledge through natural conversation. A knowledge graph engine connects insights across interviews, surfacing gaps and building a searchable institutional memory.

Started as a consumer conversational AI app for travel creators (iOS/Android), then pivoted to B2B enterprise knowledge capture based on customer discovery.
