Our story
At csky.ai, we believe that unlocking the full potential of artificial intelligence starts with one essential principle: data must remain under your control.
Founded in 2022 by two EPFL alumni, Hugo Flayac, a quantum physicist turned applied AI expert, and Stefano Zamuner, a researcher in complex systems and machine learning engineer, csky.ai was born from a shared vision: it is possible to build powerful, privacy-first AI that empowers users without compromising confidentiality.
With a background that bridges cutting-edge research and real-world industry needs, Hugo and Stefano set out to build something new: a secure, embedded AI assistant capable of understanding professional conversations, generating summaries and structured reports, all without sending a single byte to the cloud

Our values
Our core values support our guiding philosophy: giving data ownership back to the people and using AI for good.


Data privacy is at the heart of everything we do. We believe in building a world where people are the true owners of their data, and private-by-design AI helps them use it.

We actively listen and engage with each customer to understand how we can customize our technology to make the biggest positive impact on their organization.

As a company founded and led by physicists, we are naturally curious and experimental. We love solving problems and are always dreaming up new solutions.
