This is circumspace
With over 20 years of experience in web hosting, high availability and systems operations, we offer product and infrastructure development and general consulting. We thrive in areas where cloud-native, on-premises as well as privacy and free software are valued most.
What we do
On-premises hosting, but cloudy
We deliver cloud-like on-premises infrastructure without cloud-associated costs, a dozen sales calls and upselling attempts for products you don't need. Specializing in containerization, virtualization, automation and overall Linux systems operations. We're here to help and host what you need.
Architecture reviews & hardening
We audit existing infrastructure, deployment workflows and operational practices to identify bottlenecks and risk. The result is a concrete plan to improve reliability, security and maintainability without unnecessary complexity.
Automate and iterate
Specializing in Linux environments and containerization, we get rid of recurring manual tasks and build the glue between your business logic, services and day to day operations.
Through fire and brimstone
Our emergency firefighting services provide on-demand rapid problem resolution and systems recovery.
Selected experience
Interim technical leadership
Provided interim engineering management and CTO support for a German AI startup.
Freedom & permissionless Technology
We champion privacy-respecting approaches to solving problems using free software whenever possible. Our commitment to libre software principles, data minimization, and user autonomy drives every technology decision we make. We support open source initiatives for broader adoption and fundamentally believe in software freedom and user rights. If you have to ask for permission, it's not yours to begin with.
circumspace Labs
circumspace labs is our umbrella for experiments where we rapidly explore new technologies using AI assisted engineering practices.
