Custom software and AI systems, built with agile discipline.

Katjes Labs designs, builds, and ships production software, from agentic AI platforms to full-stack applications, for teams who need a partner who can lead delivery, not just write code.

What we do

Three disciplines, one practice

Brought together on every engagement, from design through delivery.

Custom software development

Full-stack applications built for real constraints: from architecture through deployment, with AI woven in where it actually earns its place, not bolted on, and code built to be maintained, not just shipped.

AI-focused solutions

Agentic systems, retrieval-augmented pipelines, and applied LLM architecture, designed for production, not demos.

Agile delivery leadership

Hands-on technical leadership for teams that need someone who can plan, unblock, and ship faster with AI-assisted engineering practices, not just advise from the sidelines.
