Alt F4

Software that outlasts the hype.

Open source since 2012 — 7,500+ stars on the Go Elasticsearch client. Procurement platforms in production at DAX-listed companies. One person you actually talk to.

What we stand for

Long-term thinking

We build software meant to run for years, not sprints.

Deep expertise

Decades of experience across procurement, logistics, and enterprise systems.

Honest craft

No shortcuts, no bloat. Clean architecture, maintainable code.

Partnership

We work with you, not for you. Your success is ours.

Modern tooling

We adopt what works. AI-assisted engineering lets us move faster and think deeper — not replacing expertise, but amplifying it.
