Keewano

Keewano builds KeewanoDB, a database for AI agents and analytics systems that need to reason over complete histories of events. It stores each entity’s raw events together in order, adds contextual and semantic layers, and lets applications query or run analysis through interfaces such as SQL, REST and MCP without reconstructing event context through separate data pipelines.
