Get a custom proposalWe build production-grade software. You own it.
Járnhaus is an AI-native software house. We build custom software for logistics companies, TMS providers, and enterprise teams that have outgrown off-the-shelf tools.
We work differently from most agencies. Every engagement starts with a written spec — we document what we're building before we write a line of code. Then we use AI to compress timelines, not cut corners. The result is software that runs in production, not just in demos.
What we build: Custom TMS and logistics platforms. Enterprise workflow automation. AI-powered data pipelines and integration layers. Greenfield systems and legacy rewrites.
Who we work with: Mid-sized and enterprise companies in DACH and Poland. Teams that need software built around their actual operations, not generic SaaS adapted with workarounds.
How we work: Small senior team — no juniors staffed on your project, no account managers between you and the engineers. We ship in focused sprints with clear specs and measurable milestones.
If your current software is bleeding budget through manual workarounds, we'll audit it and write back with a plan.
