We build apps that work

Faster than you think

Web applications are our craft. We've been building them with Ruby on Rails for over 20 years, as a project, as extra hands on your team or as your long-term maintenance partner.
From concept to launch, we love to build long-term success together.

Let's talk about your project

How can we help?

  • Your software is stuck

    Outdated, slow or hard to change. Or your developer has left and nobody dares to touch it.

    We get it back in shape. We upgrade, stabilise and document it, so you can build on it again.

  • You have an idea

    A new product, work that's still done by hand, or systems that don't talk to each other.

    One system that does exactly what you need beats three expensive products that never quite fit. Or we connect the tools you already have, so data flows to the right place automatically.

  • Your app needs an expert review

    Built by an agency, your own team or with AI tools like Lovable and Cursor. Is it secure, and can it grow?

    We go through the code, close the leaks and make sure it's ready for more users, without costs getting out of hand.

  • Your system needs a maintainer

    Security updates need to happen faster and faster, and when something breaks you want someone who jumps on it right away.

    We keep everything up and running: hosting, updates, backups, monitoring and quick help when something comes up.

Why we're faster

  • Quick and clean, now even faster

    Rails was the first framework that let you build fast without making a mess: quick and clean, instead of quick and dirty. Now we move even faster. We use AI where it makes sense, but we're the ones at the controls.

  • Experience is knowing what not to build

    We spot the detours upfront and skip them. With over 900 contributions to Rails itself, we know the framework inside out and get the most out of it.

  • Straight to the source

    You talk to the people who actually build your software, not to an account manager, project manager or other go-between. We listen first and get to know your business, not just your code. Your feedback comes straight to us and we act on it right away.

How we work

From concept to launch, we love to build long-term success together.

  1. Listen

    A cup of coffee, no strings attached. You tell us what you're running into, we ask questions.

  2. Scan

    We dig into your systems and your situation. You get a clear plan and know what it costs.

  3. Solve

    We fix, build or harden. You see progress every week.

  4. Keep it running

    Hosting, updates and support on a monthly basis, so it keeps working.
