Amutable: The Berlin Startup That Wants to Make Linux Unbreakable

In a move that has the open-source world buzzing, a new Berlin-based startup called Amutable has officially launched—and it’s already making waves. Why? Because its founding trio isn’t just any group of tech entrepreneurs. They’re three of the most influential figures in the Linux and open-source ecosystem, each with deep roots in both community-driven innovation and corporate tech giants like Microsoft.

Let’s break it down: Amutable is led by CEO Chris Kühl, a former Microsoft engineer who has now gone all-in on this new venture. The company’s engineering direction is shaped by Lennart Poettering, the legendary creator of systemd—a name that’s either revered or reviled in Linux circles, depending on who you ask. And rounding out the trio is CTO Christian Brauner, a heavyweight Linux kernel contributor known for his work on containers, namespaces, and kernel security mechanisms, with stints at both Canonical and Microsoft.

This isn’t just another startup with a flashy pitch deck. These are people who’ve built the very foundations of modern Linux infrastructure. And now, they’re setting their sights on a problem that’s been nagging the tech world for years: how do we make Linux systems truly secure and trustworthy?

The Problem: Security That’s Too Late

In their launch announcement, Amutable argues that the current approach to infrastructure security is fundamentally broken. Most systems today rely on detecting breaches after they’ve already happened—watching for anomalies, scanning for malware, and hoping you catch the bad guys before they do too much damage. But as Linux systems grow more complex, this reactive model is becoming increasingly costly, brittle, and ineffective.

The Solution: Determinism and Verifiable Integrity

Amutable’s big idea? Flip the script. Instead of constantly monitoring systems and guessing whether they’re still trustworthy, why not build systems that are provably correct from the start? In other words, make Linux systems so deterministic and verifiable that you can prove they’re in their intended state—not just assume it because nothing’s gone wrong yet.

This is a foundational shift in how trust is established in Linux infrastructure. Rather than layering security tools on top of mutable systems, Amutable wants to embed integrity directly into the system architecture. The goal? Make unexpected or unauthorized changes immediately detectable and provable.

What’s Next? The Mystery Deepens

Here’s the catch: Amutable hasn’t announced a product, published any source code, or revealed technical implementation details yet. But given the founders’ track records and the company’s focus, it’s safe to assume they’re working on something big—whether it’s infrastructure services, tooling, or a platform. The specifics are still under wraps, but the tech community is already speculating.

The Name Game: What’s in a Name?

Interestingly, the company’s name—Amutable—seems intentional. While they haven’t explained it publicly, it’s likely a play on the word “immutable,” but with a twist. It suggests that change itself isn’t the problem; rather, it’s uncontrolled or unverifiable change that’s the issue. This hints at a product or solution that embraces controlled evolution while locking down anything that could compromise system integrity.

Community First: FOSDEM 2026

Amutable’s public debut coincides with FOSDEM 2026, happening this weekend. Members of the founding team will be engaging with the open-source community, likely to gather feedback, share their vision, and maybe drop a few hints about what’s coming next.

Why This Matters

This isn’t just another startup story. Amutable represents a bold attempt to rethink how we secure the backbone of modern computing. If they succeed, they could redefine what it means for a Linux system to be “trustworthy.” And with a team this experienced and respected, the tech world is watching closely.

So, what’s next for Amutable? Will they deliver on their ambitious vision? Only time will tell. But one thing’s for sure: this is a company to watch.
