Service

AI products that survive production.

Most AI initiatives die between the notebook and the release branch. We engineer the full path — problem framing, model selection, eval harnesses, serving infrastructure, and the unglamorous 80% that makes AI dependable.

SYS/01The problem

The demo-to-production gap is where AI budgets quietly disappear.

A prototype that wows a steering committee shares almost no code with a system that serves 10,000 users at p95 < 400ms with a rollback plan. The gap is evals, observability, cost ceilings, failure modes, and data contracts. That gap is precisely what we build.

SYS/02What we build

Capabilities

Product discovery & framing

We pressure-test whether AI is the right tool before writing code — defining the metric that matters, the baseline to beat, and the cost ceiling per request.

scope: 1–2 weeks

Model selection & evals

Frontier API, open-weights, or fine-tune — decided by your latency, privacy, and unit-economics constraints, then locked in with a regression eval suite, not intuition.

eval suite: 300–500 cases

Serving & infrastructure

Inference gateways, caching, batching, autoscaling, and fallbacks. Token budgets enforced in code. Multi-provider failover as standard.

p95 budget: defined day 1

Observability & guardrails

Traces on every request, drift monitors on every input distribution, and guardrails (PII, jailbreak, topicality) that run inline — not in a postmortem.

trace coverage: 100%

Launch & iteration

Canary rollouts gated on eval scores. Post-launch, we tune against real traffic and hand over a system your team can run without us.

canary gate: automated

Full IP transfer

Everything we build — code, evals, infra-as-code, runbooks — is yours. No license lock-in, no black boxes.

handover: complete
SYS/03How we work

The approach

A sequence, because the order is the point: each phase gates the next on evidence.

01 /

Frame

One to two weeks. We define the success metric, the non-AI baseline, the unit-cost ceiling, and the kill criteria. If the business case doesn't survive this, you've spent two weeks, not two quarters.

02 /

Prove

A thin vertical slice against real data with an eval harness from day one. We measure, not estimate — accuracy, latency, and cost per request on your actual workload.

03 /

Build

Production engineering: serving infra, guardrails, observability, CI/CD with eval gates. Weekly demos against the metric defined in step one.

04 /

Ship & harden

Canary rollout, load testing, failure injection, runbooks. We stay through the first month of real traffic and transfer ownership deliberately.

FAQ

How long does a typical AI product engagement take?
A framing sprint takes 1–2 weeks, a proven vertical slice 4–6 weeks, and a production launch typically lands between 3 and 5 months depending on integration surface. We commit to dates after the framing sprint, when estimates are evidence-based rather than guesses.
Do you build on top of OpenAI/Anthropic APIs or open-weight models?
Both — the decision is driven by your latency, data-residency, and unit-cost constraints. We frequently ship hybrid architectures: a frontier API for complex reasoning with an open-weight model (vLLM-served) handling high-volume, low-complexity calls at a fraction of the cost.
Who owns the IP?
You do, completely. Code, eval suites, infrastructure definitions, documentation — all transferred. We retain nothing proprietary in your stack.
What happens after launch?
Every engagement includes a 30-day hardening period against live traffic. After that, most clients move to a light retainer for model upgrades and eval maintenance, or their team runs it solo using the runbooks we hand over.
