A quarter of the week goes on looking for answers.

Over a five-day week, that’s more than a full day.

Then come the invoices, the reports and the approvals, the same work every week.

25%of a team’s time goes on searching for answers

Three kinds of system. Each one gives your team hours back.

You bring a problem that comes back every week. We build the system that handles it, inside the tools your team already uses where we can.

Every day

Knowledge assistants

Your team asks a question and gets the answer from your company’s own documents, with the source attached.

Every week

Workflow automation and AI agents

Invoices, updates, reports, data copied between systems and chasing approvals get done. Your people review and approve the important steps.

When software doesn’t fit

Custom internal tools

Internal apps and dashboards built around how your team works, where off-the-shelf software doesn’t fit.

Not ready for a build? We also run hands-on Claude and ChatGPT training for wider teams, on their real work.

An estimate from your own numbers, not a quote or a forecast. The scoping report puts the expected savings next to a fixed price.

Method and assumptions

Hours = people × weekly hours × 46 working weeks. Cost = hours × hourly cost, which should include salary, employer taxes and overheads. One full-time person is 1,725 hours a year (37.5 hours over 46 weeks). This is an estimate from your inputs, not a quote or a forecast. The audit replaces it with your real numbers.

From a 30-minute call to a system your team owns.

  1. 30 minutes, free

    Free audit

    No preparation. You leave knowing where the hours go and what is worth automating first.

  2. Fixed fee, credited to the build

    Scoping

    A written report: the workflow map, the hours and money it should save, the system we recommend, a fixed price and a timeline. The report is yours either way.

  3. Fixed fee, weeks not months

    Build

    You see it working on real tasks early, long before handover.

  4. Ongoing support optional

    Handover

    Your team is trained, the limits are written down and the system is yours.

Agreed in writing before work starts

  • A fixed fee, set before we build.
  • Live in weeks, not months.
  • You own the code, configuration and documentation. Your accounts and data stay under your control.
  • No per-seat fees from Useful Build.
  • Important steps keep a person in the loop, and the limits are written down.
  • If a tool you already pay for can do the job, we’ll tell you.

You talk to the person who builds it.

Wasim Jalali founded Useful Build. He leads a small team and builds the systems himself.

We work remotely and in English with companies in the UK, Germany, the rest of Europe and the US, on European business hours. Those overlap with US East Coast mornings.

What buyers ask before the call.

Is this a fit for us?

The best fit is a team of 10 to 200 people with work that repeats every week and someone who owns it. It’s not a fit for one-off tasks, or when there’s nothing written down or no system to work from. If a tool you already pay for can do the job, we’ll say so.

Is the audit really free?

Yes. The 30-minute audit is free and needs no preparation. You’ll leave with a shortlist of what’s worth automating first. If there’s a clear opportunity, we propose a paid scoping at a fixed fee. That fee is credited in full against your build.

What does it cost?

Every build has a fixed fee, agreed in writing before work starts. It depends on the systems we connect, the volume of documents, the approval steps and whether you need a custom interface, so we set it after scoping. The scoping report puts the expected savings next to the price, so you can judge the payback before you commit.

What if scoping shows it isn’t worth it?

Then we tell you, and the report is yours. Sometimes the answer is a simpler fix, a tool you already pay for or no AI at all.

What does it cost to run afterwards?

Running costs are usually AI usage, hosting and any software licences, paid to those providers. The scoping report lists them next to the savings. Ongoing support from us is optional and priced in the proposal.

How quickly will we see results?

Delivery runs in weeks, not months. A simple assistant in tools you already use can be ready in about a week once documents and access are in place. Larger builds take longer. You see the system working on your real tasks early, and the timetable is fixed in the proposal.

Do we need technical staff?

No. Where we can, we build inside the tools your team already uses, and we train them at handover. Your team needs to know the work, not the technology.

Do we own what you build?

Yes. You own the code, configuration and documentation we write for you. Any reusable components of ours come with a permanent licence. Third-party software keeps its own licence terms and costs. Your accounts and data stay under your control.

Where does our data go?

We agree the providers, access rules and data handling before connecting anything, and we sign a data processing agreement (an AVV in Germany) before we handle personal data. Retention and training settings depend on the tools and plan you choose. We don’t use your data to train our own models, and we never resell it.

What if the AI gets something wrong?

We test on your real cases before handover, including ones the system should refuse or pass to a person. Important steps keep a person in the loop. The limits are written down, so your team knows when to check.

Can you train our team on Claude or ChatGPT?

Training on the system we build is always included. We also run hands-on sessions for wider teams, on their own work rather than generic prompts. We scope those to what you need.

Where do you work, and who do we contract with?

Remotely, in English, with companies in the UK, Europe and the US. We work on European business hours, which overlap with US East Coast mornings. Your contract is with Karko AI Inc., the US company that operates Useful Build. The proposal sets the currency, invoicing and terms.

Put 30 minutes in your week.

The audit is free and needs no preparation. You leave knowing where your team’s hours go and what is worth automating first. If a tool you already pay for can do the job, we’ll say so.
