## Four ways to work with us.

- ### [Product Build](https://preview.kevinludwig.com/en/leistungen/umsetzung)

  Something has to change, but it's not yet clear where the lever is.

  2 weeks

- ### [Fractional CTO](https://preview.kevinludwig.com/en/leistungen/fractional-cto)

## What you get with each offer

### 10-Day Pilot

The usual way in

A workflow eats time, or you have an idea, and you want to know whether building it pays off before you invest serious money.

In ten working days we build your workflow as a first version with your real or realistic data, your team tests it, and you get a decision paper with effort and possible savings. Flat fee.

- Duration

  Ten working days

- Outcome

  Your workflow as software, team test run, documentation, decision paper with savings calculation

An idea or a first version needs to become something that runs day to day.

Web app, SaaS, shop or internal system, ready for real use. Design, development, cloud, operations and handover to your team, all in one place.

- Duration

  Weeks, not quarters

- Outcome

  Running system, design, cloud setup, documentation, handover

### Audit

Something has to change, but it's not yet clear where the lever is.

We look at your processes, systems and data, find where little effort achieves a lot, and tell you what should come next.

- Duration

  Two weeks

- Outcome

  Baseline in numbers, action roadmap, architecture sketch, next step

## More on specific topics

- ### [AI consulting, Stuttgart region](https://preview.kevinludwig.com/en/leistungen/ai-consulting-stuttgart)

  AI consulting in Stuttgart, Reutlingen and Tübingen. With software, not slides.

- ### [Shopify](https://preview.kevinludwig.com/en/leistungen/shopify-development)

  Shopify stores that load fast and don't depend on a pile of apps.

## Three steps to the first running version.

1. 1

   ### Call

   30 minutes. You describe the problem, we ask questions. Afterwards we both know whether it's a fit.

2. 2

   ### Offer

   In writing: what we build, what you get at the end and in what timeframe.

3. 3

   ### Build

   The first version usually runs within days. Then we improve it based on real use, not slides.

## What are you working on?

30 minutes on video with Kevin Ludwig, free of charge. You describe what you have in mind; afterwards you know whether it fits and which entry point is right.
