Kevin had something we could try out after three days. So we knew quickly whether it worked before we put serious money on the table.” Matthias Monshausen Managing Director, Powerconcept Monshausen GmbH Project: app for construction plans on site. Client since 2021 ## How the 10-day pilot runs. Ten working days from the agreed start. Beforehand we put in writing what the version must do. 1. Day 3 ### A first clickable state One case runs all the way through, with your data. 2. Day 7 Commitment If an agreed checkpoint is missing on day 7, we show you a new version within five working days until all are met, provided access and data are available. For businesses only. The written offer sets out the details, and your statutory rights remain in place. ### Demo with your team You check the version against the agreed checkpoints. 3. Day 10 ### Result and decision Test run in the team, documentation and a decision paper with savings calculation.

That works when both sides are ready for it. Does this sound like you? A concrete problem that really hurts The person who decides is in the room You want a first version in days, not a spec document first You're happy to look at an unfinished first version 0 of 4 apply. Tick what fits. ### Not a fit - A formal tender with a pitch round where everything has to be fixed before the first conversation - Contractors on a day rate without a clear goal - A tool is supposed to be bought, but there's no problem to solve - Projects where nobody has time for questions and testing in the coming months ## We run products of our own. GymLabs has been running since 2020, die macher since 2026: a project portal for construction projects that we run ourselves. That's why we think about operations, support and revenue from day one on client projects. [All products](https://preview.kevinludwig.com/en/produkte) ![Screenshot of the die macher website](https://preview.kevinludwig.com/_next/static/immutable/media/diemacher.16sy_fy7ie48s.webp) die macher , Coordinating construction projects, with a project portal of our own. In beta since March 2026, open since September. ## Common questions If your question isn't here, ask it in the last row. What does it cost? We charge a flat fee, not by the hour: a fixed scope, one sum, a written offer that says what you'll end up with. How high the sum is depends on the scope, which we work out in the first call. The 10-day pilot is the smallest entry point. An audit stands on its own. A product build is planned in releases so the first version runs early. How fast can we start? A 10-day pilot usually starts one to two weeks after the call, and so does a product build. If it's urgent, tell us. How can it be that fast? AI agents take over routine programming work. What they build is checked by someone who has built and run software himself for years. And instead of months of concept work there's a short alignment and then a first version that we keep planning on together. Will it work with our systems? Very likely. We've built integrations with Shopify, SAP, Microsoft Dynamics, Lexware Office and DATEV, via APIs, webhooks or file interfaces, whatever the system offers. [See Shopify development](https://preview.kevinludwig.com/en/leistungen/shopify-development) Are you still around after the project? If you want us to be. Usually we hand over to your team with documentation. On request we take care of maintenance and updates afterwards and stay available for questions. If you want experienced support long term, book us as Fractional CTO. How do you handle data protection? We sign the data processing agreement before the project starts. Hosting is in the EU, on your own servers if needed. We know the requirements of ISO 27001 and TISAX from projects for certified clients and plan the architecture accordingly. Which services work with your data, including AI services, is set out beforehand in the data processing agreement. Why not an agency or a freelancer? With an agency, contacts often change between consulting, concept, design and development. A single freelancer often covers only part of it. With us everything is in one place, from the first version to operations, with one person responsible for the whole, even when freelancers from our network join larger projects. An AI answers here, based on this website. It can be wrong. [Privacy](https://preview.kevinludwig.com/en/privacy) ## What are you working on? 30 minutes on video with Kevin Ludwig, free of charge.
