The layer underneath a demo that has to survive real traffic.

A working model is the easy part. What stalls most AI projects is everything underneath it: evals so a regression is caught before a customer finds it, routing so cost and latency hold under load, a PII layer so sensitive data never reaches a third-party model, and a record of what the system actually did. This is unglamorous engineering, and it is the part we specialize in.

Built for production, not the demo.

01 / PRODUCTION AI

Evals, routing, and audit trails for teams whose demo cannot survive real traffic.

For a demo that has to survive real traffic. Evals that block a bad release, routing that holds cost and latency under load, and a record of what actually ran.

Usually shipped with

  • AI agent development
  • Document extraction
  • Cloud and DevOps

Not a bundle to buy. Whichever you start from, the engagement covers what the build actually needs.

02 / Scope

What we build.

  • Eval suites that turn 'it feels better' into a number you can ship against
  • Model routing across Claude, GPT, and open models for the right cost and latency
  • A PII-anonymization layer so sensitive data never reaches a third-party model
  • On-device and edge inference where data has to stay local
  • Observability and tracing so every AI decision is visible and replayable
  • Audit trails and governance built for regulated, high-stakes use

03 / Outcomes

What you can ship.

  • Eval and observability platforms for your AI features
  • Cost and latency cut without losing quality
  • Governed, audit-ready AI for regulated industries
  • Regression suites that catch quality drops before users do
  • A safe path from demo to production traffic

04 / Deliverables

Artefacts, not activities.

  • An eval suite and a scorecardThe definition of good for your feature, written down and automated, so a change can be shown to help before it reaches a customer.
  • A model router configurationWhich model handles which request, on what cost and latency budget, with the failover path when a provider degrades. Tuned against your traffic, not a blog post.
  • A PII boundaryThe layer that encodes personal data before it reaches a provider and decodes it on the way back, with the data-flow diagram your security reviewer will ask for.
  • An observability ledgerEvery request, tool call and model decision recorded as a replayable record, so a bad answer can be reconstructed rather than argued about.
  • A cost and latency budgetWhat the feature costs per thousand requests and where the time goes, with the levers that move each — usually the first thing that surprises people.

06 / Why us

Quality you can put a number on

On Brandiligence, five-part template adherence climbed from 40% to 98% on a held-out eval set with strict section checks. We turn 'it feels better' into a metric you can ship against.

We specialize in the unglamorous 80%

Evals, model routing, PII anonymization, on-device inference, audit trails. The part where most AI projects stall is the part we do best.

Built for regulated stakes

Solarpunk keeps credentials on-device; Brandiligence enforces an approved-source-only policy with a validator. We build the governance that lets AI run where mistakes are expensive.

A path from your problem to production.

  1. Week 1

    Define what good means

    Before tuning anything, we build the eval set and the metrics that define quality for your task, so every change is measured instead of guessed.

  2. Week 1–2

    Route for cost and latency

    We route across Claude, GPT, and open models, add caching and fallbacks, and tune until it holds up under real load at a cost that makes sense.

  3. Week 2–3

    Lock down the data path

    A PII-anonymization layer, on-device inference where data has to stay local, and audit trails on every action, built for regulated use.

  4. Week 3–6

    Ship with a safety net

    Regression suites catch quality drops before users do, with safe rollout, rollback, and observability on everything in production.

Every service ships on the same delivery framework.

This is less a separate architecture than the one underneath all the others: a scoped token at identity, the plan-act-check-adjust loop on the agent runtime, personal data encoded through the PII vault before a model router picks for cost and latency, guardrails verdicting on the way out to your systems, and a record on the observability ledger at every step. Whichever service you buy, this is what is holding it up.

Production-proven

Built by engineers who've already shipped this in production.

The questions buyers actually ask.

It works in the demo and falls over in production. What is missing?

Usually the 80% nobody scopes: evals so quality is measured, routing for cost and latency under load, a clean data path, and observability to catch regressions. That gap is exactly what we close, and it is most of the real engineering.

How do you keep our sensitive data safe?

A PII-anonymization layer so sensitive data never reaches a third-party model, on-device or edge inference where data has to stay local, and audit trails on every action. We have shipped this for legal and executive-operations clients where a leak is unacceptable.

How do you prove the AI is actually getting better?

With evals and regression suites, not vibes. On one legal build we measured template adherence climbing from 40% to 98% on a held-out set. You get a number that moves, and an alert when it drops.

We already have evals. What would you add?

Usually three things: a baseline anyone can reproduce, failure modes named rather than an aggregate score, and the eval wired into the deploy path so a regression blocks a release instead of being noticed later.

Does the PII layer slow the feature down?

It adds single-digit milliseconds on the encode and decode. That is far less expensive than the alternatives teams reach for, which are usually routing everything to a local model or not sending the data at all.

How do you decide which model to route to?

On measured cost, latency and quality per request class, re-measured as providers change. The router is configuration you own, so when a lower-cost model gets good enough you flip it without a rebuild.
