Let’s talk
At a fixed price.

Product development We build your software product with you. You know the price of every stage before it starts.

You get working software early and see it grow piece by piece. The code is yours from the first day.

Tell us what you want to build

For founders and companies who want to build a new web app or platform, or take an existing one further.

Where you are

You have an idea or a product.
We build it with you.

  • We have an idea that a few people are already waiting for. We need a first version they can use.
  • We built our app ourselves with AI tools. Now more people use it than we planned for.
  • Customers are asking for a big new feature in our live product. Our team already has plenty to do.
  • We’d like an AI agent in our product. We have ideas, but we don’t know which one to build first.
  • Our business has run on the same software for years. Now we need to replace it without stopping daily work.

How a project runs.

After each step, you see the result and choose the next one with us.

  • Getting started

    A first conversation

    You tell us what you’re building or planning and where you want to take it. We ask questions, say plainly what we think and suggest how to start on the concept. Then you decide whether we go ahead.

  • Together

    From spec to working software

    You tell us what your software should do. We turn that into a concept and then a spec. We build in stages, often starting with an MVP. Each stage has its own fixed price, agreed before it starts.

  • Your call

    What comes next

    We plan the next stage, which gets its own offer. Or we keep working in your team each month, as forward-deployed engineering. If your plans change along the way, we look at the change together. What happens then depends on your project.

Client voices

What clients say
about working with us.

Work with a team at Zurich University of Applied Sciences.

“Our work with Zone2 has covered APIs, web applications and identity management within our existing systems. They work independently, take ownership of the technical details and involve us when decisions need our input. They also provide practical training that helps our team build its own skills.”

“We rely on Zone2 for their exceptional technical skills and strategic insights. Their ability to align with our long-term goals has made them an indispensable partner.”

Topics

We work on these
in a project or in your team.

  • AI-built apps

    You built your app yourself with AI tools. We go through it with you, show you where it stands and make it secure and stable without starting over.

  • AI agents and workflows

    We build AI agents and workflows for your product or your internal systems. We start with one narrow use case or a prototype you already have. Then we take it into production together.

  • Modernising legacy systems

    We modernise your legacy system step by step, while it keeps running. Where it makes sense, we rebuild parts from scratch. We can also connect the system to AI agents and new tools through APIs.

  • Keycloak

    We set up and change Keycloak for your applications and for AI agents that act on behalf of your users. It runs on your infrastructure. We also offer ongoing monthly support.

Questions

Who owns the code?

You do, from the first day. The same goes for the concept, the spec and everything else we build. The code lives in your GitHub or a similar service from the start. If you don’t have an account yet, we start in ours and transfer the code to you later.

What happens to our data when you build AI into our product?

We sign a data processing agreement, agree on the hosting and don’t use your data for training. You decide which models and providers we use. We’re an EU company ourselves, so we set everything up under EU law.

Do you use AI coding tools on our code?

We talk this through in our first meetings. If your company has rules for AI, we follow them. When we use the tools, the agent runs in a sandbox with no access to production or live data. Secrets, keys and customer data stay out of the tools. Together we work out where a person reviews the work and where the tool works on its own.
