No retrieval grounding
Answers come from the model's memory, not your data — and they're confidently wrong.
The gap isn't the model.
It's the engineers.
We build the production system around your prototype — grounding, evals, fallbacks, cost control — and get you live in 8 weeks.

The Problem
So you switch models.
It's still broken.
When an AI product misbehaves, the instinct is a bigger or newer model. It rarely helps — because the failures users actually hit live in the engineering, not the model.
No evals
Every prompt tweak or model update can quietly degrade quality — nothing measures it.
No fallbacks
One provider outage or rate limit and the feature simply stops — with no plan B behind it.
No cost or latency controls
Token spend and response times look fine at 10 users — then both balloon at 10,000.
No observability
No traces, no alerts, no dashboards — failures stay invisible until a customer hits one.
A better model makes a good demo slightly better.
It does nothing for any of the above. That's the gap — and it's an engineering gap.

Bring whatever you have — a Lovable prototype, a half-shipped MVP, a demo that keeps stalling. You'll walk away knowing exactly what it needs.
The Difference
Where the demo ends and
the product begins.
Week 0 — The DemoWhere most AI products start: a working demo.
Week 8 — In ProductionThe same product after our 8-week engagement.
Evals
It gives a good answer when you run the demo script — nothing checks how it does on everything else.
Every change is scored against test cases, and anything that makes answers worse is blocked before it ships.
Fallbacks
When the model provider has an outage or slows down, your users see an error page.
If a provider fails, the system retries or switches to a backup — your users never notice.
Cost Control
You find out what the AI usage cost when the invoice arrives at month-end.
AI spend is tracked in real time, with budgets and alerts before costs climb.
Grounding
Answers come from whatever the model memorized in training — plausible, but not verifiable.
Answers are pulled from your own documents and cite their sources, so they can be verified.
Observability
There's no way to detect that something broke — you find out when a customer reports it.
Dashboards and alerts show your team what's happening before customers feel it.
Ownership
How the system works lives in the head of whoever built it — nothing is written down.
Decisions are documented, every type of failure has a written step-by-step fix, and your team is trained to run it without us.
How We Work
Production-ready in 8 weeks.
Four stages, each with a deliverable you can hold us to — and the discipline that makes the speed safe.
Engineering audit
We map the fragile points in your build and what production will actually require of it.
Week 1Architecture & hardening
Grounding, fallbacks, evals, cost and latency controls — the plumbing demos skip.
Week 2-4Ship to production
Real data, real load, with observability designed in from day one.
Week 4-7Handoff
Documentation, dashboards, and knowledge transfer so your team owns it.
Week 8Speed without rigor is just faster failure. AI compresses our timeline — the testing, security, and architecture stay non-negotiable.
Why Appening
The difference is who does
the engineering.
Playbooks don't ship products. Engineers do — and ours have shipped enough AI-native systems to know exactly where they break.
AI-native from day one
RAG pipelines, agent frameworks, and eval harnesses are our engineers' everyday tools — patterns hardened across the 100+ products we've shipped, not learned on your budget.
Senior by default
Senior engineers lead every engagement — they design the architecture, own the evals, and work inside your sprint cadence from day one.
You own it after
Everything ships with the docs, dashboards, and tests your team needs to operate it independently. You own the code and the know-how.

FAQ
Questions, answered.
Rarely. Most production failures — wrong answers, downtime, runaway cost — come from missing engineering (grounding, fallbacks, evals, monitoring), not the model. A better model improves the demo, not the reliability.
