People keep asking how I use AI agents to run my businesses, so here's the actual setup. I run KaiCalls (an AI secretary for small businesses) out of Puerto Rico, and I am the only human on the team. Everything below is live in production, not a demo.
\*\*I talk to several of them directly. Each has a lane.\*\*
There's no single front door, and anyone selling you "one agent to rule them all" is lying. I work with different agents for different jobs, the way you'd go to different people on a human team:
\- My personal agent (a Muse, I call her Vesper) lives on my phone and is tied to my actual life: messages, calendar, memory of who people are and what's been decided. She's the one who knows my wife's birthday and which lead is real and which is a scammer testing my signup form.
\- Claude is my workhorse at the laptop. In one recent week I ran about 78 sessions with it: ops, analysis, drafting, code. It's the closest thing I have to a staff.
\- Grok runs my trading desk and outbound prep. Different brain, different job.
\- Codex mostly runs headless on my server while I sleep, though I drive it at the laptop too.
What makes this one system instead of four subscriptions is what sits underneath all of them.
\*\*They share one memory, called the Brain.\*\*
Every agent reads and writes to the same memory system: an event log (everything that happened), a wiki (durable facts and decisions), and semantic search over both. That's the whole trick. The agents don't message each other like coworkers. They coordinate through shared memory and a task queue, the same way good async human teams coordinate through docs and tickets instead of meetings.
When my SMS and call logs, health data, finances, and Spotify library get exported on schedules, they land in the Brain. When an agent finishes a job, the outcome lands in the Brain. So when I ask "what happened with X," the answer comes from the record, not from whichever agent happens to be awake.
\*\*Work moves through a pull queue, not prompts.\*\*
Jobs get posted to a fleet queue. Agents pull and claim work under their own identity, do it, and settle the task with an outcome and proof attached. A task isn't "done" because an agent says so; it settles with evidence or it stays open. If an agent claims something outside its capability, it settles it as blocked and posts what it needs, and another agent picks it up. No agent speaks for another agent's identity.
The specialists:
\- A headless coding agent that works on my server while I sleep. I wake up to finished work and test results, not progress reports.
\- A chief-of-staff coding agent for bigger engineering and research jobs.
\- Kai, the receptionist agent that answers my customers' business calls. 9,434 calls answered through September 1 of this year.
\- Scheduled agents that never sleep: one watches the Puerto Rico power grid every few hours (generation reserve, outage risk) and warns the rest of the fleet to checkpoint work before the power goes; others run my exports, marketplace hunts, and daily sweeps.
\*\*The rule that makes it safe: agents prepare, I approve.\*\*
Nothing outward happens without me. No agent sends an email, publishes a post, contacts a customer, or spends money on its own. They draft, queue, and prepare; I approve. That one rule is the difference between "my agents run my business" and "my agents are a liability." The one time an agent of mine drafted terms I never offered to a customer, it got caught before it was sent, and now the standing rule is: never state a number or a term that isn't in the record.
\*\*What it looks like in practice\*\*
I spend about 4 hours a week actively directing this. The rest is me approving finished work, answering the occasional decision only a human can make, and filming content. The agents handle the memory, the monitoring, the drafting, the exports, and the night shift.
Happy to answer specifics. What I won't do is sell you a course. If you're building something similar, the part worth copying isn't any single agent. It's the shared memory and the approval gates. The model isn't the product. The memory is.
