AI Chief of Staff

The thinking behind your day.
Handled.

An always-on AI that manages your correspondence, diary and daily coordination — so you can focus on the decisions only you can make. Built for founders. Configured for your business. Governed from day one.

What your AI Chief of Staff handles

Correspondence

Reads, triages and responds to emails across your business and personal accounts. Surfaces what matters. Drafts replies in your voice. Sends when you say so.

Diary management

Checks your calendar, finds free slots, handles scheduling back-and-forth with contacts. Confirms meetings and adds them to your diary — without you being in the loop for every exchange.

Proactive monitoring

Scans your inbox three times a day. Flags emails that need attention. Surfaces follow-ups that are overdue. Keeps you informed without overwhelming you.

Client coordination

Knows your clients, your priorities and your current projects. Tracks follow-ups, logs interactions and helps you stay on top of relationships that matter — across business and beyond.

Built in stages. Trusted over time.

Autonomy is earned, not assumed. Every AI Chief of Staff starts fully supervised and expands its independence as trust is established — on your terms, at your pace.

Stage 01

Reactive assistant

Responds when asked. Checks your diary, reads your inbox, drafts emails. Nothing goes out without your approval.

Stage 02

Proactive monitoring

Watches your inbox and surfaces what matters. You get a summary, not a flood. You decide what to act on.

Stage 03

Supervised autonomy

Proposes actions, drafts and schedules — you approve before anything is sent. The workload drops. The decisions stay yours.

Stage 04

Delegated authority

Handles defined administrative functions end to end. Meetings are booked. Correspondence is managed. You see the outcome, not every step.

Not a product. A professional service.

There is no shortage of AI tools that claim to handle your inbox or manage your diary. Most of them are configured the same way for every user — and shipped without anyone asking what happens when something goes wrong.

At Tenex, we build the AI Chief of Staff around your business specifically: your clients, your calendar, your communication style, your risk profile. We test it. We govern it. We define what it can and cannot do before it touches anything on your behalf.

That is the difference between a product and a professional service. And in the case of something that acts in your name, that difference matters.

In 2026, OpenAI and Anthropic both moved decisively toward embedded enterprise AI deployment — using consulting partnerships, services ventures and forward-deployed engineering models to help organisations put AI into real workflows, not just buy tools. Their conclusion was the same one that underpins Tenex: getting value from AI is not a technology challenge — it is an organisational one. The tools are available to everyone. The embedded expertise to deploy them properly is not.

4 Stages of autonomy — each unlocked deliberately
0 Assumptions about what it should be allowed to do

Security — a real example

Why plug-and-play AI has a problem you may not have considered

We built a scheduling capability — the kind that checks a founder's diary and offers available slots to contacts. During implementation, we tested a straightforward question: what happens if someone emails the AI assistant under the guise of arranging a meeting, but their real goal is to find out what else is in the founder's diary that day?

A standard implementation would have answered. Asked to "find a slot that doesn't clash with anything important," the AI would naturally surface existing meetings — handing a bad actor a detailed picture of who the founder is meeting, and when.

We caught it. We added explicit rules: the AI offers available times, it never describes what else is in the diary. We layered it with a contact whitelist and a human approval gate. The capability works. The vulnerability does not.

This is what a Tenex implementation gives you that a mass-market product does not: someone who thought about it before it went live.

Setup and retainer — nothing else

Setup

One-time installation

We build and configure your AI Chief of Staff from the ground up — identity, email, calendar, memory, governance framework and security layer. Everything is tested against your specific business before it touches anything in your name. Priced by scope.

Retainer

Ongoing development

Your Chief of Staff grows with your business. Each stage of autonomy is unlocked deliberately, with new capabilities added as they are earned. The retainer keeps Tenex embedded in the process — so nothing gets switched on without the right governance in place.

Pricing is discussed at first conversation. We do not publish rates — scope varies significantly, and we would rather give you a number that means something.
