We tell you where AI is worth it. Then we build it and keep it running.

For companies that want AI inside the software they already use, and an honest answer first about where it will pay off. We build assistants, search over your own files, multi-step AI tasks (agent pipelines) and MCP servers. Each one is connected to your real systems and tested on your real cases.

First step

System Review · fixed price · within a week

Often the honest answer is a simple rule or a basic link between two systems, and the report says so.

Where this usually starts

Situation 01

Everyone says you need AI. Nobody has said where.

The board wants a plan. But nobody has said which of your tasks AI would improve, which it would make worse, and what each would cost per month.

Situation 02

The pilot worked on the demo data.

On real questions it guessed, or showed someone a private document. The cause is usually missing access rules, stale data and no test questions, rarely the AI model.

What walks in

What people usually tell us about AI, and what we do about each

02

“Customers ask the same questions every evening, or search and find nothing.”

We write the answers down as real pages and catalogue data, then let an assistant answer only from them and hand everything else to a person.

05

“We were told to do AI, but our data cannot go into a public chatbot.”

First we decide where it is hosted, which AI provider to use, how long data is kept and what is logged. Only then is any data loaded, and AI tools get access that is recorded and checked.

How a job starts here

One conversation, then a diagnosis, before anyone quotes

Free technical meeting → System Review, credited to the build → fixed-price Build → monthly Run.

01

Start: What You Bring Us

In the free technical meeting, bring one real example of the work, where its data lives and who may see it.

Once the work is agreed: study the work, not the hype, then one task live first, then measure and make it safe, then run and extend.

How we think

Three rules behind every AI system we ship

01

Advice comes before code

AI in the wrong place adds cost and delay to every request, and a new way to be wrong. Where a simple rule or a good search box works better, we say so.

02

Most of an AI system is not AI

A working AI system is mostly ordinary software: task queues, access rules, checks and logs. We use AI only where something must be read or written, because plain code is cheaper and easier to test.

03

The model is a replaceable part

We build on the Anthropic Claude API, the OpenAI API or Google Vertex AI behind one shared layer. When a provider retires a model, switching is a settings change and a test run.

FAQ

Questions people ask before AI work

For specific tasks, yes; as a general goal, rarely. It pays where your team spends hours weekly reading, sorting or drafting, not where a rule would do.
It depends on the task. Your first live AI task gets a fixed price before any code is written. We also estimate the AI usage fees with you up front. Current prices are on our pricing page.
Often, yes. For staff writing or research, a team subscription is cheaper. Custom work pays off when AI must use your data, work inside your systems or talk to customers.
It stays in your systems. Only the information a request needs is sent to the AI provider, and we agree on that limit before we build.

Want to know where AI would actually pay off?

Bring one task your team repeats every week. We will tell you honestly whether AI belongs there, and what it takes to connect it to the systems you already use.
