AI Operating System · a service

A private AI Operating System, installed and run for you.

I install and operate a private AI chief of staff that knows your work and proactively makes you better at it every day. It lives on infrastructure you own, learns from your email, documents, and meetings, and is ready in about two weeks.

Offered under my own name, on my own time, and with consent from my employer.

What it is

A chief of staff made of software.

This is the productized version of the system I run for myself every day. Think of it as a private chief of staff made of software: it reads your inbox, your documents, and your meeting transcripts, remembers what you committed to, drafts your replies, and briefs you every morning. Unlike a chatbot, it works proactively and on a schedule. Unlike a human assistant, it knows your context from day one and costs less than your cloud bill.

Everything runs on infrastructure you own: a machine on your desk, or a private cloud box. Your keys, your data, your machine. I am the operator on a monthly retainer, and you can revoke my access in ten minutes and keep the whole system running.

Who it's for

Senior operators drowning in their own context.

It is built for people who bill by the hour and lose hours to email, transcripts, and context-switching: independent consultants, fractional executives, solo lawyers, coaches, and small-company founders. If you have considered hiring a chief of staff or an executive assistant and decided the math did not work, or that the right person would still need a year to learn your world, this is the alternative.

What you get

The install, day fourteen.

Everything below, set up, tested, and handed over.

Your own machine or private cloud box, configured to your preferences.
An organized knowledge vault built on a structure proven to work with the agent.
Six months of email, your documents, and your meeting transcripts ingested and searchable.
A 7 AM daily digest of yesterday and today, in your inbox and on your phone.
Morning email triage that sorts your inbox and drafts replies in your voice. Nothing sends without your approval.
Three custom skills built around the procedures you actually repeat.
A phone assistant you can ask anything, by text or voice.
A nightly cost report, a tested kill switch, and a printed runbook.

How it works

Fourteen days, intake to handoff.

A guided install with a check-in midway, so nothing is a surprise at the end.

Week one

Foundation and memory

Provision your machine and lock down the security posture.
Install the agent and seed it with your professional context.
Ingest your email, documents, and meeting transcripts.
Stand up daily notes and your morning digest, then tune tone and scope at a mid-week check-in.

Week two

Skills, mobile, and handoff

Turn on email triage with human-approved drafts.
Build three custom skills with you, on real examples.
Wire the phone assistant, add cost caps and observability.
Run a security review, test the kill switch together, train you, and hand over the runbook.

How I keep it safe

Built so you stay in control.

You own everything: your box, your keys, your data. I operate; you hold the keys.
Human in the loop: anything that sends email or takes an outside action waits for your approval.
Hard cost caps and a daily spend report, so there are never surprises on the bill.
A kill switch you test yourself that stops everything and leaves your data intact.
A handoff document so the system is yours to keep, or to hand to another operator, at any time.

Start with a free, thirty-minute discovery call.

Most calls end without a sale, and that is fine. The goal is to find out whether this is genuinely worth your money before either of us commits.
