Everyone's suddenly building company brains.
Despite lacking a universal definition, all modern company brain architectures perform four core functions: ingesting signals, retaining memory, dreaming and pruning, and speaking and searching.
Ingestion & Signals
Company brains capture data from varied sources ranging from personal feeds like email and calendar to multi-tool enterprise stacks like Slack, Drive, Jira, and GitHub.
Memory & Graphing
Memory management varies from explicit programmatic storage and cross-session agent retention to version-controlled markdown repositories and time-aware knowledge graphs that preserve historical state.
Dreaming & Pruning
Nightly batch jobs, background agents, and automated PR generation handle staleness detection, re-linking, and iterative memory cleanup.
Speaking & Searching
Retrieval spans simple text matching like grep to ranked fact retrieval and human-approved publishing loops.
