From a second opinion to hands-on delivery.
Whether you need someone to roll up their sleeves, a second opinion or an independent look from outside, you pick the format that fits your situation.

Together with you, we implement CI/CD pipelines, Kubernetes platforms, cloud migrations or event streaming with Kafka until your team can run it on its own.

Advisory
An experienced architecture team on call: ask as many questions as you like. We answer by email and arrange a call when needed.
A good fit When you regularly need a well-founded second opinion.
Continuous Architecture
We support your teams on an ongoing basis, keep architecture decisions traceable and the documentation up to date.

AI in critical systems
Anyone can build faster today. We make sure you can also answer for it.
We make AI-assisted software development fit for critical and regulated systems. There, speed is not the bottleneck. The question is who stands behind the result and can prove it.

Our DNA
drei + IT + tier = dreITier
No slide-deck architects. Techies who run a company.
We support you on three tiers: strategy, architecture and automation. That's where our name comes from. That, and the fact that three of us founded dreitier ("drei" is German for three). We come from development and operations, not from sales. And that's exactly the knowledge we pass on: Sharing Experience.
More about us →Build and run
We don't just know how to develop software. We know how to keep it stable in production at three in the morning.
Honest answers
No ChatGPT copy-paste, no Stack Overflow folk wisdom. Real people with real names who tell you when others can help you better.
Commercially minded
We run a business ourselves. The latest hype is rarely the most economical solution, and we'll tell you so.
Remote-first
We work distributed and asynchronously with you, anywhere in the DACH region, without travel costs or endless meetings.
