← All solutionsSolution · Retrieval and evals

Stop your AI being confidently wrong

Retrieval tuned on your own content and scoped per user, grounding checks on what the model claims, and an eval set built from your real failures that runs in CI. When someone changes a prompt, a test fails before a customer notices.

Who it is for

Assistants and search features that give wrong answers nobody can explain, and teams afraid to touch the prompt.

What we can build for you

Six things we can put in your product, each backed by work we have already shipped.

01
Hybrid search
Vector and full-text search fused by rank, with thresholds set by measurement.
02
Retrieval scoped per user
Private data never reaches someone else's answer, enforced in the query, not the prompt.
03
Grounding checks
Numbers and claims checked against what the model actually read, and regenerated when they fail.
04
Eval sets from your failures
Golden cases built from real bad answers, in Langfuse, Braintrust or plain code.
05
Evals in CI
Checks scored by code that fail the build, and model-judged scores that only advise.
06
Prompt-injection hardening
User content treated as data, never as instructions.

The four tests, for this

Where this kind of feature usually breaks, and what passing each test looks like.

01 · Design
Does it feel right?

Answers say what they rest on, and say so plainly when the data is missing.

02 · Mobile and backend
Does it hold up?

Search stays fast under load and degrades gently when a source is down.

03 · AI, retrieval and evals
Most at risk
Is it right?

Every claim traceable to retrieved content, and every change scored before it ships.

04 · Metering and pricing
Does it pay?

Retrieval that fetches less and better, so each answer carries fewer tokens.

Closest track: Fix retrieval, add evals

How the two weeks go

€6,000, fixed. Written findings on day five; stop there and pay half. You keep everything either way.

  1. Days 1 to 4Instrument retrieval: what was fetched, used and missing. Build an eval set from your own failures.
  2. Day 5Findings: failure rates by type, and whether the cause is retrieval, the prompt or the data.
  3. Days 6 to 9Fix retrieval with measured thresholds and per-user scoping, and gate the build on the evals.
  4. Day 10Handover: evals in CI, so the next change is a measurement, not a vibe.
