Artificial Intelligence

AI prototypes demo well and fail quietly in production: answers that cannot be traced to a source, behavior that changes with a model update, costs that scale with usage, and no way to tell whether a change made things better.

Overview

What we deliver

We build AI systems the way we build any production system — with defined success criteria, evaluation datasets, retrieval you can audit, guardrails, tracing and a deployment path — so the behavior you tested is the behavior you ship.

Who this is for

  • Teams with a promising AI prototype that cannot be defended for production use.
  • Organizations with large document estates that people search manually.
  • Support, operations or back-office functions with high-volume, rules-heavy workflows.
  • Product teams adding assistant or copilot features to an existing application.
  • Engineering leaders who need AI behavior to be auditable and cost-bounded.
Problems we solve

What usually brings teams to this work

No definition of correct

Quality is judged by demo impressions. We define task-level success criteria and build an evaluation set before changing the system.

Answers without provenance

Users cannot verify a response. We enforce retrieval grounding and citation so every claim points at a source document.

Silent regressions

A prompt or model change breaks a case nobody re-tested. We run evaluation suites in CI as a release gate.

Permission leakage

Retrieval returns content a user should not see. We apply access filtering at query time, not after generation.

Unpredictable cost and latency

Token spend grows with adoption. We set budgets per interaction, cache aggressively and route simpler tasks to smaller models.

Agents that wander

Open-ended loops with unclear termination. We constrain agents to defined tools, bounded steps and human checkpoints for consequential actions.

Capabilities

How the practice breaks down

Each capability below is a discrete piece of work with its own deliverables. Engagements usually combine several.

01

Retrieval-augmented generation (RAG)

The problem

General models cannot answer questions about your policies, contracts, tickets or product data, and guessing is worse than refusing.

What we implement

An ingestion and retrieval pipeline: document parsing, chunking strategy, embeddings, hybrid search, reranking, and generation constrained to retrieved context with citations.

How it works

Retrieval quality is measured separately from generation quality, so failures are attributed correctly. Access control is applied in the query so users only retrieve what they may read.

Expected outcome

Answers are grounded in sources users can open and check, and the system declines rather than inventing when evidence is missing.

Typical deliverables

  • Ingestion pipeline with incremental re-indexing
  • Chunking and embedding strategy with rationale
  • Hybrid retrieval and reranking configuration
  • Citation enforcement and refusal behavior
  • Retrieval evaluation set and scoring harness

AI agents and workflow automation

The problem

Multi-step processes need tool use and decisions, but unconstrained agents are unpredictable and hard to audit.

What we implement

Supervised agent workflows with a defined tool surface, explicit state, step and cost limits, deterministic handling for anything consequential, and human approval checkpoints.

How it works

Each tool call is validated and logged, so a completed run can be replayed and reviewed. Deterministic code handles what does not need a model.

Expected outcome

Automated workflows that can be inspected step by step, with humans retaining control of decisions that matter.

Typical deliverables

  • Agent architecture and tool contracts
  • State machine or graph definition with termination rules
  • Audit trail of steps, inputs and tool calls
  • Human-in-the-loop approval points
  • Failure and fallback behavior

Evaluation and quality engineering

The problem

Without evaluation, every prompt change is a guess and every model upgrade is a risk.

What we implement

Task-level evaluation datasets drawn from real inputs, automated scoring for what can be scored, structured human review for what cannot, and regression runs in CI.

How it works

Evaluation runs on every meaningful change and on model version updates, with results tracked over time so quality movement is visible rather than anecdotal.

Expected outcome

Changes are shipped on evidence, and a model or prompt update that degrades a case is caught before users see it.

Typical deliverables

  • Evaluation dataset and labelling guidance
  • Automated scoring harness with regression thresholds
  • CI integration as a release gate
  • Human review workflow and rubric
  • Quality trend reporting

Document intelligence

The problem

Critical information sits in scanned PDFs, forms and inconsistent templates that resist search and extraction.

What we implement

A parsing pipeline with layout-aware extraction, OCR where needed, schema-constrained structured output, confidence scoring and review queues for low-confidence results.

How it works

Extraction returns typed data validated against a schema, and anything below a confidence threshold is routed to a person rather than passed downstream silently.

Expected outcome

Structured, checkable data from unstructured documents, with uncertainty surfaced instead of hidden.

Typical deliverables

  • Parsing and OCR pipeline
  • Extraction schemas and validation rules
  • Confidence thresholds and review queue
  • Accuracy evaluation set per document type

LLMOps: deployment, observability and cost control

The problem

AI features fail differently from ordinary services, and standard monitoring does not show why an answer was poor.

What we implement

Tracing of prompts, retrieved context, tool calls, tokens and latency; caching; model routing; rate limiting; and per-feature cost budgets with alerting.

How it works

Traces link a user complaint to the exact context and calls that produced the response, which makes debugging a data question rather than a guessing exercise.

Expected outcome

Production behavior is observable, spend is bounded and predictable, and rollouts are staged rather than global.

Typical deliverables

  • Tracing and prompt-logging implementation
  • Cost and latency dashboards per feature
  • Caching and model routing strategy
  • Rate limiting and abuse protection
  • Deployment pipeline with staged rollout

AI governance and guardrails

The problem

Deployment stalls because nobody can explain what the system will and will not do with sensitive data.

What we implement

Input and output filtering, PII handling rules, prompt injection defences, data retention decisions, model and vendor selection criteria, and documented human oversight.

How it works

Controls are implemented in code and tested like any other behavior, and each decision — including which data may reach which provider — is written down.

Expected outcome

Security and legal reviewers get concrete answers about data handling and system limits instead of assurances.

Typical deliverables

  • Guardrail implementation and test cases
  • Data flow and retention documentation
  • Prompt injection and abuse test suite
  • Model selection and change policy
  • Human oversight definition per use case

  • Success criteria
02

Design

Choose the architecture — retrieval, extraction, agentic or deterministic — and design evaluation before implementation.

  • Guardrail requirements
03

Implement

Build ingestion, retrieval, application and guardrails against the evaluation set from day one.

Back-office workflow automation

Multi-step processes with tool calls, validation and approval checkpoints for consequential actions.

Product copilot

In-application assistance scoped to a user's data and permissions, with bounded cost per interaction.

Prototype hardening

Why Protogenies

How we work on this

Evaluation first

We define how quality will be measured before building, so improvements are demonstrable rather than asserted.

Grounding over generation

Most enterprise AI value comes from retrieval and data quality. We invest there before tuning prompts.

Deterministic where possible

If a rule, query or workflow engine solves it, we use that. Models are applied where they add something a program cannot.

Bounded cost and blast radius

Budgets, rate limits, staged rollout and human checkpoints are part of the design, not later additions.
