We are engineers, not an agency. You talk to the people who write the code and rack the servers. If we are not the right partner, we say so in the first email.
Philipp Liermann, founder

Common questions.

Do you take over existing systems?
Yes. Most engagements start with an audit of what is already running. We document what we find, fix what is urgent, and take over operations when it makes sense.
Where is our data hosted?
In the European Union, usually in German datacenters. Either on our bare metal or in your own datacenter. GDPR-compliant by default, with contracts to match.
How do you charge?
Fixed price for defined scope, monthly retainer for operations. No per-seat licenses, no hourly billing theater. You get one invoice per month.
Do you offer support contracts?
Yes, with defined response times. Critical incidents reach an engineer directly, not a ticket queue.
English or German?
Both. Contracts, documentation, and calls in whichever language your team prefers.

Thirty minutes with an engineer.

No sales, no slide decks. We reply within one business day.
