Keewano launches a database for agent memory

Keewano launched KeewanoDB and disclosed a $12 million seed round for a database built around agent event history. Its launch announcement says the system processes trillions of events in parallel and does not charge per event, but those are vendor claims rather than an independent latency benchmark. Teams building long-lived agents should price retention, context freshness, and query latency against the search API cost benchmark before adding a new data plane.
