KeewanoDB: event database for AI agent analysis, raises $12M seed

Israeli startup Keewano unveiled KeewanoDB, a database that stores events in their original sequence for AI agent reasoning. The company raised $12 million in seed funding led by Hetz Ventures. It queries 250 million events in half a second and prices by MAU rather than per event.

• KeewanoDB keeps each entity's event sequence contiguous and ordered, without precomputed aggregates
• Queries 250 million events in 0.5 seconds using SIMD acceleration of 10 events per instruction
• Pricing is based on monthly active users, not events; free plan covers 3M events and 27,000 MAU
• The $12M seed round was led by Hetz Ventures with a16z speedrun and Remagine Ventures
