Activity from announced rounds
Speedrun is an a16z investment program. Its company directory includes Circle Games and Keewano, linking the program to mobile-game development and infrastructure for working with event histories.
RoundOS records participation in Circle Games’ Series A and Keewano’s seed round, as well as a lead role in Orbits’ pre-seed financing for an AI household assistant. Other covered activity includes Cascade’s construction-business software and ZeroDrift’s AI communications compliance tools. This page follows the Speedrun program’s recorded activity.
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.
