Run by one person who's done this before.
Limestone AI Labs is a small, deliberately-shaped managed IT practice for small businesses. One operator, one tenant model, one promise: the work is visible, the runbooks are real, and the AI is leverage rather than theatre.

Fifteen-plus years building and supporting infrastructure for teams of every size, including larger enterprise data center environments where uptime, change control, documentation, and calm execution are not optional.
That experience is the reason Limestone is built the way it is: small-business IT with the habits of a much larger shop, without the overhead.
Limestone is the practice I wished existed for the businesses in between. Microsoft 365 set up like someone's going to outgrow it, not just survive in it. Identity that actually has a backbone. Documentation you can hand to the next operator. And AI applied where it earns its keep — triaging tickets, drafting replies, summarising the month — without dressing up the work itself.
I write everything down. I tell you when I'm wrong. I'd rather lose a deal than pretend I'm fit for it.
Three things we believe.
- 1. Transparency is a product feature.
Every ticket, every change, every monthly summary lives in your portal. You should be able to read what we did at 2 a.m. without sending an email. If we can't explain a piece of work in writing, we probably shouldn't be doing it.
- 2. The runbook is the product.
The point isn't to do the work once — it's to do it once, write it down, and never burn that hour again. Our value compounds because our runbooks compound. When you cancel, you get the runbooks. They're yours.
- 3. AI doesn't replace operators — it removes the typing.
Triage classifies. The model drafts. A human still reads, still decides, still owns the outcome. The AI is in the seam between "ticket arrives" and "human starts thinking" — that's the part worth automating.
Email is the front door.
