How we work

How we work,
across every offer.

Whichever offer you start with (Training, Audit & Consulting, or Build & Run), the engagement runs on one discipline and ends the same way: your team owns the AI agents and runs them without us. Below is how that plays out, from the shared method to the four deliberate phases of a production agent build.

One path

One path to
AI autonomy.

The three offers are rungs of one ladder. You can step on at any rung; the discipline behind each is the same, and the endpoint never changes: your team masters the AI in-house.

Training gets your people fluent (Understand). Audit & Consulting tells you where AI is worth it and where it isn't (Decide). Build & Run designs, ships, and operates the AI itself (Implement → Operate). Whatever the rung, three habits run through every engagement: we scope before we act, we lead with evidence over opinion, and we leave artifacts you own, vendor-portable, with no dependency on SDEN baked into the next step.

That is what 'autonomy' means here. We are not optimizing for a long retainer; we are optimizing for the day you no longer need us. The more we work together, the less you depend on us, and every deliverable, from a training recording to a production codebase, is written to be picked up by your team without us in the room.

The method, in depth

The Build & Run method,
phase by phase.

When the work is to build and operate AI in production, here is exactly how it runs: four deliberate phases, each ending in artifacts you own, plus the engineering disciplines that keep the system honest and free of debt.

01
Phase 01

Scoping & architecture

Scoping & architecture

What this phase produces

  • Written problem statement with measurable success and eval criteria
  • Architecture diagram + decision log (ADRs), including the build-vs-buy and 'AI vs not' call
  • Risk register ranked by exploitability and business impact, with EU AI Act classification where it applies
  • Data-readiness read for any AI use case (sources, quality, access, retention)
  • Go / no-go recommendation, with the scope we would commit to
02
Phase 02

Design & prototyping

Design & prototyping

What this phase produces

  • Interactive prototype of the highest-risk flows, running on real data
  • Model and architecture decision (model choice, RAG / fine-tune / agent) with written rationale (ADRs)
  • An eval harness: a graded test set and the metrics production will measure on every change
  • Cost and latency budget per AI path, named up front
  • Design system (tokens, components, accessibility baseline)
03
Phase 03

Development & hardening

Development & hardening

What this phase produces

  • Production-grade application in your repositories, deployed to staging
  • Test and eval suites covering success paths, error paths, edge cases, and AI quality
  • Guardrails and cost ceilings wired in (input/output checks, spend limits)
  • Security review against the OWASP Top 10, the OWASP LLM Top 10, and the relevant ASVS level
  • Load and chaos test results against the documented traffic shapes
04
Phase 04

Delivery & support

Delivery & support

What this phase produces

  • Staged production release with feature-flag rollout
  • Operational runbook for every routine production task
  • Monitoring of SLOs and AI behavior: quality, drift, hallucination rate, and cost
  • On-call playbook for the incidents the risk register anticipated
  • Handover of the prompts, evals, and guardrails, with documentation for the next engineer
