AI-accelerated Infrastructure & security

We build it. We secure it.
Then we prove it.

From data centers to Microsoft 365: infrastructure designed by a senior engineer, configured with AI-driven automation, and handed over with evidence.

Track record

Selected engineering work.

Client names stay private. Ask us about the work.

  1. Enterprise

    A 5,000-person insurance company, built and run end to end.

    Its data center, a Nutanix and Rubrik core, Meraki across 120-plus sites, and company-wide Citrix.

  2. AI for IT operations

    Hundreds of governed AI tools for an enterprise IT team.

    Two dozen MCP servers, read-only by default, every call logged behind SSO.

  3. Legacy data

    Tens of millions of documents rescued from retired systems.

    Millions of records recovered into PostgreSQL, searchable behind SSO.

  4. Healthcare

    A regional hospital's storage and compute, rebuilt remotely.

    PowerStore and Nutanix over NVMe/TCP, with Citrix workloads moving now.

  5. AI infrastructure

    Network design for a GPU data center.

    SONiC switch plans for a 100-server pod, hardware through MQ3 Labs.

  6. Nonprofit

    A 65-device fleet audited and made trustworthy.

    NinjaOne cleaned up and a Microsoft 365 migration scoped.

How we work

From discovery to handover.

One engineer runs all four steps. No hand-offs between sales, design, and build.

  1. 01
    Discovery

    A read-only look at your environment. No changes.

  2. 02
    Design

    A written plan: the build, the cutover, the rollback, the price.

  3. 03
    Build

    Configured remotely with AI-driven automation. Every change reviewed and logged.

  4. 04
    Handover

    Docs, runbooks, and the evidence package. You own all of it.

Partner Hardware & licensing
MQ3 Labs

Hardware and licensing through MQ3 Labs.

MQ3 Labs quotes and fulfills equipment and licensing. Limestone handles design, configuration, and cutover. You can also bring your own equipment and licenses.

Teams that have outgrown winging it.

For in-house IT teams and organizations that need engineering support.

Size
Five seats or five thousand

One office or a hundred sites.

Stack
Microsoft on top, whatever underneath

Microsoft 365 and Entra on Nutanix, Proxmox, or Citrix.

Trigger
A deadline or a scare

Storage out of support, a doubled hypervisor bill, a failed audit, an acquisition.

Reach
Remote, anywhere

Based in Fort Worth, working nationwide. Racking stays local.

Questions

Common questions.

Do you offer ongoing support?
Ask us. Most work starts as a scoped project. Tell us what ongoing support you need, and we will work out what fits.
Where do you work, and with what size teams?
We work remotely across the country, from five-person businesses to multi-site enterprises. Limestone is based in Fort Worth.
Do you install hardware?
We plan the room, racks, power, and network, then configure the systems remotely. Your team or the colocation's remote hands usually handle racking and cabling; we can coordinate a local installer.
How do you use AI in the build?
AI-driven automation performs configuration, auditing, and reporting. Work starts read-only; changes need approval and engineer review, and every action is logged.
How is a project priced?
After a short discovery, you receive a written quote before work starts. Fixed fee or hourly depends on the project. There is no published rate or price list.
What is in the evidence package?
Logs, configuration exports, and runbooks document the build. Security findings map to NIST CSF 2.0 and CIS Controls for review by your team, insurer, or auditor.
Who supplies hardware and licenses?
Our reseller partner MQ3 Labs can quote and fulfill them. You can also use your existing equipment or supplier; Limestone handles the engineering either way.
How big is Limestone?
One senior engineer, backed by AI-driven automation. The engineer scopes the work, reviews every change, and owns the outcome; automation handles configuration, auditing, and reporting.
