Software development and integrations

Custom systems, integrations and internal tools, built by the same people who then run them. We write the code so the next developer, or you in a year, can build on it without starting over.

30 minutes with Emil. We want to understand what you need before we suggest anything.

What we build.

Custom systems

Web apps and platforms with a clear architecture, from the first version to production.

Integrations

Systems that talk to each other, such as Fortnox or your business system, with retries on failure and logs you can read.

Internal tools

The spreadsheet that became business-critical, rebuilt as a tool that handles more users.

AI in the business

MCP servers and automation with clear permissions and logs, so you know what the AI is allowed to do.

Websites

More than thirty delivered. Custom-built when control matters most, WordPress when you want to update it yourselves.

Running it after launch

We run what we build, with monitoring, updates and someone who answers when it breaks.

No slide decks. A proposal with a price.

A meeting

You describe the problem. We ask about what decides the scope.

A proposal

A fixed price for a well-defined project, or hourly when the scope needs to take shape. Nothing starts until you say go.

Build and run

We deliver in small steps you can try. After launch, we run it.

Fjellride

Booking, inventory and payments for seasonal rental operators: bikes, skis and watersports. We built all of it from the first line, from the booking pages and the staff tools to card payments and bookkeeping in Fortnox. Then Fjellride took the system over in its own name, and we co-own the company.

Common questions.

What does it cost to build a custom system?

It depends on the scope. A well-defined project gets a fixed price, otherwise we work hourly at SEK 1,500 per hour. After the first meeting you get a written proposal with a price.

Who owns the code?

You do. The rights to what we build for you pass to you as set out in the order, usually on full payment. The exception is our own tools and libraries, which you get a perpetual licence to use in the delivery.

Can you take over a system someone else built?

Yes. We start with a review of the code and how it runs, and tell you what is worth keeping and what needs rebuilding.

Do you use AI when you develop?

Yes, as a tool for coding, debugging and documentation. We review everything before it is delivered and only use AI services that don't train on your content. If you'd rather we didn't, you say so in the order.

What technology do you use?

Whatever suits the system and the people who will take it over. Often TypeScript, React and Next.js for the web, and cloud services such as Google Cloud or Vercel.
