Most people are buying AI backwards. They stack up copilots, agents, and a pile of tools that never talk to each other, then wonder why nothing actually compounds. The piece almost everyone is missing is a company brain: one unified intelligence that connects every tool, call, and document so your agents and your team can finally execute as one.

In this video I show you exactly how we built ours at Single Grain, running on 500,000 tokens of persistent memory, 90+ daily crons, and 2,800 sales-call transcripts turned into operational playbooks. Then I break the whole thing down as a stack you can build yourself: capture, retrieval, source of truth, permissioning, feedback loops, and execution. Get these layers right and the system learns, protects, and compounds, which is how one person ends up doing the work of ten and the revenue follows.
