For companies that have outgrown Excel

A custom business app for your people

Does your company run on spreadsheets, emails and paper? Information gets copied from one place to another and nobody has the full picture? We build an app that fits how your company really works — not the other way round.

You don't need to know whether you need a web or a mobile app. Show us the process that slows you down most.

A warehouse employee holding a tablet with a task list

Sound familiar?

A spreadsheet only one person understands

When they are ill or leave, nobody knows where anything is.

Retyping from paper

People fill in paper forms and someone retypes them into the system. Twice the work, twice the mistakes.

Approvals by email

Requests, orders and holidays get lost in inboxes.

The software doesn't fit

You bought a system, but people still keep their own spreadsheets because it can't do what they need.

What your people will be able to do

See their tasks

Who, what and by when. No digging through emails.

Fill in forms on a phone

Right where the work happens — with photos, signatures and without signal.

Approve in one tap

Requests, orders or holidays go straight to whoever approves them.

Find information

Procedures, documents and contacts in one place.

Work with what you already have

Connections to accounting, stock or other systems, so nothing is retyped by hand.

And management has the overview

The state of tasks, jobs and numbers without assembling reports every Friday.

Website or mobile app? We'll work that out

Office work usually happens on computers, field or warehouse work on phones or tablets. A business app often combines both parts on the same data.

We recommend it based on where your people actually work — not on what is fashionable.

When a ready-made tool is enough

There is off-the-shelf software for many things — attendance, invoicing, stock. If it fits, use it. A custom app makes sense when:

  • you have a process the software doesn't know, or you have to work around it,
  • you retype data between several systems,
  • you need to bring several tools into one place for your people,
  • you pay for licences you use a fraction of.

Frequently asked questions

Isn't it more expensive than off-the-shelf software?

At first, yes. It pays off when people work around the software or you pay for many licences. In the design we tell you honestly whether it will pay back in your case.

Do we have to change how we work?

No. We design the app around how you work and simplify only what slows you down.

Can it connect to our accounting or stock system?

Usually yes, depending on the system you use. We check it during the design.

Can artificial intelligence be part of it?

Yes. Repetitive tasks such as processing documents, emails or orders can be automated by our sister brand Grow-AI.

How long does it take?

We work in two-week cycles and you try every finished part straight away. A simpler first version can reach people within a matter of months. You get an exact timeline together with the price after the first conversation.
