Practice Area 02 · AI Systems & Automation

Put AI to workwhere it pays—and prove that it does.

Document extraction, cited knowledge search, and workflow automation built into your operation—with tests that measure accuracy, controls on cost, and a person in the loop where it matters. And if plain software does the job better, we’ll tell you.

01 · Where AI Pays

Four places where AI earns its keep in real operations.

Each one starts with your real data and ends with a system you can measure, audit, and own.

01Document Extraction

Your team spends hours copying data from PDFs, invoices, and forms into your systems.

AI reads the document. Plain code checks the result. People only see the uncertain cases.

What is happening
Layouts change, scans are messy, and template-based OCR breaks every time a supplier updates a form.
How we approach it
Totals add up, tax IDs are valid, required fields exist—checked by plain code, not by the model. Only the uncertain cases go to a person; everything else flows straight into your ERP or database.

What stays in your repository

  • A pipeline that turns raw documents into validated database records
  • Validation rules and confidence thresholds that decide what a person reviews
  • Direct integration with your ERP, database, or internal tools
Discuss your documents

02Internal Knowledge Search

The answer is somewhere in your documents. Nobody can find it—and a chatbot that guesses is worse.

Answers grounded in your documents, with the exact source—or a plain “not found.”

What is happening
Procedures, contracts, and manuals are spread across thousands of files. Generic chatbots invent plausible answers or ignore who is allowed to see what.
How we approach it
We build it as a search problem first. Every answer cites the exact paragraph it came from—or says plainly “not found in the documentation”—and respects your access permissions.

What stays in your repository

  • A private search index that respects your access permissions
  • Answers that link every claim to its source paragraph
  • A test set that measures retrieval accuracy and catches made-up answers
Discuss your knowledge base

03Workflow Automation & Agents

The same requests every day: check three systems, decide, act, repeat.

Agents that do the routine work—inside limits you define.

What is happening
Support tickets, vendor onboarding, compliance checks: routine work that still needs a person to gather context from several systems before taking a standard action.
How we approach it
We don’t hand an agent the keys. The workflow is modeled step by step: AI classifies and drafts, while code controls which tools it can use, what it is allowed to do, and when a person must approve.

What stays in your repository

  • A workflow engine with explicit steps and a full log of every action
  • Controlled connections to your CRM, ticketing, or internal APIs
  • An approval screen for any action with real consequences
Discuss your workflow

04From Pilot to Production

Your AI pilot impressed in the demo. In production it’s slow, inconsistent, and the bill keeps growing.

Tests, cost control, and safeguards that turn a promising pilot into a dependable system.

What is happening
Every prompt tweak breaks something else, answers vary from one day to the next, nobody knows the cost per transaction—and one bad answer to a customer could become a public problem.
How we approach it
We treat prompts like software. We build a test suite from your real edge cases and run it on every change, split one giant prompt into smaller verifiable steps, send simple tasks to cheaper models, and add caching and protection against manipulation.

What stays in your repository

  • An automated test suite that runs on every change
  • Model routing with fallbacks, structured outputs, and cost tracking per transaction
  • A faster, cheaper architecture ready for real volume
Discuss your pilot

02 · How We Work

A model is one component. Reliability comes from the software around it: validation, tests, and a person where the stakes are high.

How We Take AI to Production

  1. 01

    Feasibility Test

    A fixed-price test on your real data. If plain software or a simple query does the job better than AI, you hear it here.

  2. 02

    Measure Before Building

    We agree on the accuracy you need and test against your hardest real cases before building anything around it.

  3. 03

    Production in Your Cloud

    Deployed in your infrastructure with validation, fallbacks, monitoring, and human review where it matters.

Standards

  • Never Trust Raw Model Output

    Every response is checked against schemas and business rules before it touches your data or triggers an action.

  • Your Data Stays Your Advantage

    Enterprise agreements with zero data retention, or models running in your own cloud. Your data never trains anyone else’s model.

  • Measured, Not “Vibes”

    Every system ships with tests and logs, so you know how it behaves—and when it changes.

03 · Start a Conversation

Let’s find out if AI pays off for your case.

Tell us about the workflow or documents you want to automate. We’ll tell you whether AI is the right tool. We take on a limited number of engagements at a time, so you always get senior attention.

Common Questions

No. We use enterprise endpoints with zero data retention (AWS Bedrock, Azure OpenAI, Google Vertex AI, or direct enterprise APIs), or open models running inside your own cloud.

By limiting what the model is allowed to do. Knowledge answers must cite their source. Extraction and automation results are checked against schemas and business rules, and uncertain cases go to a person.

Every system ships with a test suite built from your real cases, plus tracking of accuracy and cost per transaction. You see the numbers before launch and after every change.

No. Your code talks to models through a clean abstraction, so you can switch or mix Claude, GPT, Gemini, or open models as prices and capabilities change.

Yes—real-time voice agents for phone or in-app conversations, connected to your CRM and business rules, with the same guardrails as any other workflow. As with everything else, we start with a feasibility test on your real scenarios.

A clear picture of the manual workflow you want to improve and a small sample of real examples—say, 10–20 representative documents or tickets. We handle the rest.

With a fixed-price feasibility test on your real data, so you know whether it works—and what it would cost to run—before committing to a full build. Scope and price are agreed in writing before work starts and depend on your case, not on a rate card.
