Start with a
free
consultation

Tell us about your work and current setup. We will also tell you honestly whether the cloud or on-premises fits better.

What We Do

We build and support infrastructure and generative AI for growing businesses

Private LLM / RAG Platforms

Search, summarize and draft with generative AI without sending your documents outside.

Infrastructure Automation

Server and network settings as code, so anyone can build the same environment.

Operations and Handover

We run what we build, and leave code and runbooks so it can be handed over at any time.

About Zephya

The engineer who designs it also builds and runs it

At Zephya, our founding engineer handles everything from design and build to operations. No hand-offs between teams means faster conversations and clear responsibility.

Kept as code and runbooks

The setup is managed as code and handed over with runbooks, so nothing depends on one person.

Honest about what fits

If the cloud is the better choice, we will say so. We never push on-premises for its own sake.
