Otter & Stein
Cleverly conceived. Solidly built.

Websites, AI and software for your business.

We design your presence, connect your tools and build what you are missing. Directly with the makers — engineering, software, embedded.

What we do.

Three areas, each with its own page. Each starts with a conversation and ends with something that runs.

How we work.

A prototype in days, not months.

First conversation

30 minutes

You tell us what hurts. We tell you whether and how we can help.

Quote

Fixed price or capped hours

A clear frame with a cap. No surprises, no website-builder rent.

Prototype

in days

You see early what is taking shape and steer along. Iteration instead of a novel-length spec.

Handover

with source code

Source code, documentation, instructions. You don't depend on us — but we stay within reach.

You talk to the people who build.

One team — everyone with a clear part.

Backend & Security Architect

Lukas Koch

Backend, hosting and security — plus more than nine years of embedded development: firmware, sensors, IoT.

Knowledge Systems Architect

Richard Frank, Dipl.-Ing. (FH)

Helps build the company memory: how knowledge is stored, linked and found again in the system. Plus planning and visualisation.

Sales & Client Success

Daniel Lenzenhuber

Your contact from the first enquiry into day-to-day operation: quote, coordination, support. Works with the systems we build every day.

Backend & Security Developer

Raffaele Fusco

Works with Lukas on backend and security.

AI Systems Architect

Nicolas Lekai

Designs the interfaces. Comes from web development and visual effects and still builds the systems behind the images.

Otter & Stein is the software and AI sister of the Bergwind planning office in Füssen. If you have a building project, you will find us there; if you need software, here.

For a first conversation, this is enough:

  • What should work better? One sentence is enough.
  • Which tools do you use today (email, accounting, CAD, shop)?
  • What would be a good result for you in three months?
