RedTag.studio

We build digital products. And run them.

RedTag is a product company and technology partner. We build our own SaaS and open-source products, help our clients build theirs, and create the infrastructure that keeps them secure, deployable and reliable.

Products built from real-world problems.

We build products for problems we know first-hand. From creating digital experiences to securing identities and delivering software into complex enterprise environments.

Built in the open.

Open source is part of how we build software. We rely on open technologies every day, contribute reusable components back to the ecosystem and publish tools that solve problems we encounter while building and operating products.

Build repeatable VM appliances for your software.

KubeBoot provides declarative tooling for turning an application into a reproducible VM appliance and installation workflow with Kubernetes installed.

We do not just advise product teams. We are one.

The same engineers who build and operate our own products help our partners design, modernize and run theirs.

Long-term product partnerships

We work with selected partners where we can take real responsibility for the product. From architecture and engineering to deployment and long-term operations.

From card management to modern identity infrastructure.

We helped GITRIX evolve a card-management product into a modern platform for secure identity and multi-factor authentication. RedTag designs, builds, deploys and operates the platform across customer environments.

From idea to production. And everything after.

We solve these problems for our own products every day.
We can solve them for yours.

Building software is only part of the job. It also needs to be delivered, secured, updated, monitored and operated.

Run your product. Not your infrastructure.

We help product teams build the engineering platform behind their product so they can focus on the product itself.

CI/CD & Software Supply Chain

Ship faster. Know what you are shipping.

We design and optimize CI/CD pipelines, automate dependency management and add software supply-chain controls to your development process.

CI/CD · Dependency management · Supply-chain controls

Kubernetes & Platform Engineering

A platform your team can actually operate.

We design, deploy and operate Kubernetes environments and give development teams a consistent platform for running their applications.

Kubernetes · Rancher · Flux CD

Identity & Access

One identity layer across your infrastructure.

We deploy and integrate identity providers and SSO so users, developers and internal services share a consistent authentication and authorization model.

Keycloak · ZITADEL · SSO

Zero Trust Access

Expose services without exposing your network.

We design Zero Trust access for internal applications and infrastructure so access is based on identity instead of network location.

Pomerium · Identity-aware proxy · Access policies

Secure Infrastructure

Security built into operations.

We help product teams harden servers, automate configuration and reduce the operational surface that needs manual management.

Ansible · KubeBoot · Perimeterd

Enterprise Software Delivery

Your software. Their infrastructure. Still under control.

We create repeatable delivery models for products that run inside customer environments.

VM appliances · On-premise · Fleet management

Take the next step with a team that runs products.

We can review your current product architecture, delivery process or infrastructure and help define the next step.

Not sure where to start?

Whether that means simplifying CI/CD, moving workloads to Kubernetes, improving security or redesigning how your software reaches customers, we can help.

Portrait of Martin Kluska

Founder & CTO

Martin Kluska

Since 2010, I have built and grown technology products as an entrepreneur and CTO. My work began with an investment in an IT company. Since then, I have launched startups (Capturio app, Lucky Bastard brewery, faceout app). Some with successful exits, others that became valuable lessons. Since 2024, I have focused on building and scaling cybersecurity products. I take on difficult challenges and see them through.

Portrait of Peter Schiffer

Site Reliability Engineer

Peter Schiffer

I am an independent Site Reliability Engineer with more than 15 years of experience in Linux, software engineering and infrastructure automation. At Red Hat, I worked on Linux and container technologies. At Slido, I helped modernize AWS infrastructure and migrate applications to Kubernetes. Today, I design and operate cloud and on-premises systems, using Terraform and Ansible to automate infrastructure and application delivery. Building and operating GITRIX showed us the practical challenges of deploying software in customer environments. These experiences inspired the Distro Ops tools. I focus on reliable services, repeatable deployments and clear long-term maintenance.
