Who it’s for

  • Founders with an MVP to launch

    You have validated the idea and want a solid first version to show customers and investors, without rebuilding everything a year later.

  • Companies outgrowing spreadsheets

    Orders, bookings, stock or customers managed in files and messages. An internal app brings order and removes repetitive work.

  • Teams extending an existing product

    You already run a platform and want a mobile app, a customer portal or integrations with other systems.

What’s included

The exact scope is set in the brief; these are the parts we usually cover.

How it works

Four steps, the same on a two-week fix or a year-long build.

  1. A 30-minute call

    Tell us what you’re building or what needs improving. In 30 minutes, we’ll explore your goals, discuss the options and give you an honest view on whether we’re the right fit.

  2. Agree and sign the brief

    We agree the scope, deliverables, milestones, price and what’s excluded. You sign the project brief and contract before work begins, so both sides know what to expect.

  3. Follow the build

    You get a private web page with progress updates and preview links to try the work. We use Claude to help prepare updates, then review them before sharing. We remain responsible for the work and its delivery.

  4. Launch and hand over

    You own the code, the designs and the accounts. Documentation included, support if you want it.

Frequently asked questions

Straight answers to what people ask before booking a call.

How much does a mobile app cost?

The Product & AI package starts at €5,000 + VAT and covers a well-defined MVP or internal app. More complex apps with payments, integrations and admin tools are quoted in phases. After the call you receive a written scope with a fixed price or a phased plan, not an hourly estimate.

How long does app development take?

A well-defined MVP usually takes six to twelve weeks, depending on features and integrations. The exact timeline is set in the brief, with intermediate milestones you can test.

Native apps or one codebase?

For most products, one codebase for web, iOS and Android cuts cost and time without giving up device features such as location or notifications. We recommend fully native only when the project really needs it, for example heavy graphics processing.

Who owns the code and the accounts?

You do. The source code, designs, cloud accounts and app store accounts are in your name, with documentation included. You can continue with us or with another team.

What happens after launch?

Defects in the delivered scope are fixed free of charge for 30 days. For ongoing development, monitoring and updates we agree a care plan or a monthly collaboration with clear hours and priorities.

Other services

Most projects combine two of these. We help you start with what you need now.
