Build the control layer for the age of AI.
AI agents are moving from answering questions to taking actions across businesses. Someone needs to make sure they operate within the rules.
That's what we're building at Qastel: an independent AI governance platform that helps enterprises discover, govern, and control AI across their organization.
Our mission
Keep humans in control of AI.
AI is becoming one of the most powerful forces shaping our world. It's moving beyond answering questions to making decisions, taking actions, and operating autonomously.
This transformation will redefine how we work, how businesses operate, and ultimately how society functions.
But as AI becomes more powerful, one principle must remain non-negotiable: humans must stay in control.
We're building Qastel to make that possible. An independent control layer that gives organizations the power to set boundaries, enforce their rules, and hold AI systems accountable for their actions.
We believe the future of AI should be defined by the people it serves, not the technology that powers it.
Built in Europe. For a world powered by AI.

Our values
How we build matters as much as what we build.
Three simple principles guide how we work, with our customers and with each other.
Customer First
We start with real customer problems, not assumptions. We listen, challenge ourselves, and build what creates measurable value for the people who use our product.
Bias for Action
We move fast, take ownership, and favor action over endless discussion. We ship early, learn quickly, and improve continuously.
Act Responsibly
We build technology that businesses can trust. We take security, privacy, and the consequences of our decisions seriously, without compromising our ambition to move fast.
