The platform

MythOS.

Agents at desks, one connector for Claude, and answers read from the machine.

Desks

Agents you can talk to

Each agent has a desk, a standing self, and a memory. Every reply carries the model and what it cost. No hands on your systems.

One link

Sign in. Get one link. Paste it.

Read from the machine

Answers you can check

Patch state, backup health, who has admin: read from your systems on demand.

Who we are

A few people in Atlanta.

We have run IT for businesses for years. Ask, and we'll introduce you to a client.

How we start

Conversation, then a scope in writing.

Four clear steps, from the first conversation through ongoing support.

Free

Conversation

How many people and machines, what stack, and what's slow, fragile, or unknown.

In writing

Scope

What we would do, what it costs, who signs off.

Inside your tenant

Work

In your own Microsoft 365, with your person able to see every change.

Ongoing
