One system.
Every action.

We connect the systems you already run, build AI tools into every department, and orchestrate them under real governance — for companies and the public sector.

Most organizations already have the data to run better. It's scattered across a dozen systems that don't talk to each other — and in the heads of the people who've been there longest. We build the system that turns it into decisions.

/0.1 The architecture

One architecture. Built from the ground up.

Your existing systems stay. We organize the data, cut a tool to fit each department, and orchestrate across all of them — with a person in charge of every decision that matters.

01 Your existing systems

Nothing gets ripped out.ERP · CRM · Accounting · Email · Spreadsheets

The data you already have stays where it is. We connect to it — including the spreadsheets living on individual desktops and the knowledge that's never been written down.

02 Limestone

The data foundation.Always built first

Every engagement starts here. Every source flows into one continuously updated database that you own — the foundation every tool and decision above it stands on.

  • Automated pipelines — no one uploads files by hand
  • Row-level security — each team sees only its own data
  • You own the database and everything in it
03 Ashlar

Tools cut to fit each department.Collections · Scheduling · Purchasing · and more

Ashlar is stone cut and squared for one exact place in the wall. Each tool is built into one department's daily work — review queues, drafted letters, one-click reports. Push-button. No prompting.

  • AI drafts and flags; your people decide
  • Every tool shares the same foundation
  • The output of one becomes the input of the next
04 Keystone + Plumb

Orchestration, with governance built in.Agents · Closed loops · Audit

The keystone locks every stone in the arch. Keystone coordinates agents across functions and closes the loop — every real-world result feeds back to sharpen the next decision. Plumb keeps it true: every agent tested, scored, versioned and logged.

  • Cross-functional decisions, priced with the math shown
  • A person approves every consequential action
  • Every query, change and approval on the record
05 Lantern

The leadership view.Daily, not month-end

The lantern is the windowed cap on a dome that lets the light in. Lantern puts the whole operation on one screen — the numbers, the exceptions and the decisions waiting on you — so leadership runs the business from live data instead of last month's close.

One system

One structure. One operating system.Built from the ground up

Put together, the layers become a single structure: your existing systems at the base, the Limestone Foundation on top of them, a tool for every department, orchestration that ties them together — and leadership looking at all of it. Governed end to end.

/0.2 In production

Not a pilot. A running system.

Real tools, running every day inside the companies we serve — one comprehensive interface, built on one foundation.

Scheduling board: crew lanes by day with equipment and weather flags, and a proposed plan awaiting dispatcher approval.

Every crew, machine and forecast on one board.

Drag-and-drop crew lanes with equipment, utility locates and rain-outs built in — and a nightly re-plan that proposes next week before anyone asks. A dispatcher approves.

/0.3 Ashlar

A tool for every department. One foundation under all of them.

Every Ashlar tool is cut to fit how one team actually works — and because they share the Limestone Foundation, each one makes the next one smarter.

/01

Collections

Daily worklist, AI account reads, drafted outreach, human approval.

/02

Scheduling

Crews, equipment and constraints — with a plan proposed nightly.

/03

Purchasing

Demand-driven buys, supplier lead times and pre-build stock checks.

/04

Estimating & Proposals

Every proposal captured, priced to your rules, tracked to the win.

/05

Invoicing

Work completed becomes an invoice queue your team approves.

/06

Inventory

Statistical safety stock, record accuracy and risk-based counts.

/07

Demand Planning

A measured forecast per product family — and its accuracy, improving.

/08

Customer Service

The veteran's knowledge at every desk, on every call.

/09

Relationship Intelligence

Every email and meeting captured, scored and surfaced — no data entry.

/10

Field Operations

The day's work, check-ins, photos and notes on a crew lead's phone.

/11

Pricing Rules

One governed rule book, versioned — the AI never invents a price.

/12+

Yours next

If a team re-keys it, reconciles it or tallies it by hand, it's a candidate.

/0.4 Who we build for

Same architecture. Two kinds of mission.

Companies

Run the whole business on one set of numbers.

Manufacturers, distributors, field-service and professional-services firms whose data lives in systems that were never built to talk to each other.

  • Manufacturing · Distribution
  • Field services · Trades
  • Professional & advisory firms
Explore the platform Public sector · Limestone Civic

Built for service. Not surveillance.

Cities, counties, state agencies and other public agencies stretching flat budgets across rising demand. The public owns the data; residents get one answer.

  • Municipalities · Counties
  • State agencies · Public agencies
  • Regulated data excluded by design
Limestone Civic
/0.5 Plumb · Governance

Built to be trusted with the things that matter.

A mason's plumb line checks whether a wall is true. Plumb does the same for every agent we deploy — and these ground rules hold on every build.

01

You own it

The database, the automations and the prompts live in accounts you control. If we part ways, everything keeps running.

02

A person decides

AI drafts, flags and recommends — with its evidence shown. Every consequential action waits for human approval.

03

Everything is on the record

Every query, change and approval is logged. Every agent has a test suite, a score and a version history.

04

Your data never trains a model

We operate under commercial API terms that prohibit training on your data — a contractual guarantee, not a setting.

05

No single-model bet

Models are chosen per task and swappable. Quality is monitored before outputs ever reach production.

06

Built for handoff

Documented, deterministic by design and readable by your IT team — so it can run without us.

/0.6 How we work

One team, from the first conversation to a running system.

Strategy, build and stewardship in a single engagement — sequenced by what your organization is ready to absorb, so every wave produces a win people trust.

01

Discovery

We map the workflows that matter, on site, with the people who run them.

02

Roadmap

Every opportunity scored by impact and feasibility, sequenced into waves.

03

Limestone

The data foundation comes first. Always. It's the most important thing we build.

04

Ashlar

Tools go live one trusted win at a time, with your team in the loop.

05

Keystone

Orchestration closes the loops — and Plumb keeps every agent true as you grow.
