AI App Development

AI features that survive contact with real users.

We build retrieval, agents and automation into products that already have customers, with the evaluations, guardrails and cost controls that separate a production feature from a conference demo.

The demo is the easy ten percent.

Anyone can wire a model to a text box in an afternoon. The work starts when the feature has to be right on the thousandth request, stay inside a budget, and fail in a way your support team can explain.

We treat an AI feature like any other piece of production software: it has acceptance criteria, a test suite, monitoring and an owner. The model is one dependency among several, and it is swappable.

Included

  • RAG and search over your documents, tickets, catalogue or codebase
  • Agents and workflow automation wired into the tools your team already uses
  • Evaluation harnesses, prompt regression tests and human-in-the-loop review
  • Model routing and caching tuned to keep unit economics sane at scale

What you end up with

An AI feature in production with evaluations, guardrails and a cost per request you can actually forecast.

The difference

Prototype vs. production AI

Most AI projects stall between these two columns. Closing that gap is the service.

AI prototype

  • Works on the five examples it was built against
  • Prompt edits shipped on instinct, regressions found by users
  • No idea what a request costs until the invoice arrives
  • One model, hard-coded, with no fallback
  • Answers with confidence whether or not it has the facts

Production AI feature

  • Scored against an evaluation set that grows with every bug
  • Every prompt change runs through regression tests in CI
  • Per-request cost and latency tracked and budgeted
  • Routing, caching and fallbacks across providers
  • Grounded in your data, cites sources, and knows when to hand off

What we build

What we build with AI

Four shapes cover most of what teams actually need. Many products end up combining two.

  1. Retrieval and knowledge search

    Question answering over your documents, help centre, tickets or codebase, with chunking, hybrid search and citations so answers can be checked.

  2. Agents and workflow automation

    Multi-step agents that read, decide and act inside your CRM, helpdesk or back office, with approval gates wherever an action is hard to undo.

  3. Document and data extraction

    Structured data out of invoices, contracts, forms and emails, validated against a schema and routed to a person when confidence is low.

  4. AI features inside existing products

    Drafting, summarising, classifying and recommending, added to the app you already have, behind a feature flag, measured against the workflow it replaces.

Process

How the work runs, phase by phase.

Each phase ends with something you can see, use or sign off.

  1. Frame the problem

    We pin down the task, the baseline it has to beat and what a wrong answer costs. Some problems turn out to need a rule and a database query, and we will say so.

  2. Build the evaluation set

    Real examples with known-good outputs, collected before any serious prompt work. It becomes the definition of done and the regression suite.

  3. Prototype against the evals

    Retrieval strategy, prompts, tools and model choice are iterated against scores rather than impressions, so progress is measurable.

  4. Harden for production

    Guardrails, rate limits, caching, fallbacks, tracing and cost budgets. Human review is added where the stakes call for it.

  5. Launch and tune

    A staged rollout behind a flag, with live traces feeding new cases back into the evaluation set. Your team gets the runbook and the dashboards.

Timelines

How long it usually takes.

Typical ranges for well-scoped work. Discovery comes first and produces a fixed quote and a date.

Feasibility spike

1–2 weeks

A scored prototype on your own data and a go / no-go recommendation.

Single production feature

4–8 weeks

One workflow, evaluated, monitored and rolled out behind a flag.

Multi-agent system

8–16 weeks

Several tools and approval paths, integrated with internal systems.

FAQ

AI App Development: common questions.

Do we need to train our own model?

Almost never. Retrieval over your data plus a strong general model covers the large majority of business use cases, costs far less and improves every time the underlying model does. We recommend fine-tuning only when the evaluations show a gap that nothing else closes.

How do you stop it making things up?

You cannot remove the risk entirely, so we design around it: answers are grounded in retrieved sources and cite them, outputs are validated against schemas, low-confidence cases are routed to a person, and the evaluation set measures the error rate so it is a known number rather than a surprise.

What happens to our data?

It stays in your accounts. We use provider configurations that do not train on your inputs, keep retrieval indexes in your own infrastructure and document exactly what leaves your network and why.

What will it cost to run?

We measure cost per request during the prototype and give you a forecast at your expected volume before you commit to a build. Caching and routing cheaper models to easier requests usually bring it down substantially.

Can you add AI to our existing product?

Yes, that is the most common engagement. We work inside your repository and ship the feature behind a flag, so nothing changes for users until the numbers say it should.
