A small, senior team that builds for you — not at scale. For you.
Tavellion d.o.o. builds Avellion — AI assistants that run on your own hardware, with your data staying yours. We're a compact, founder-led team: the people you talk to are the people doing the work.
On-prem. Your data. Your call.
We build on what we think the next decade of enterprise AI should be: models that run where your business runs, and software where you own the outcome.
On-prem first
The Assistant runs on a server inside your building — no third-party cloud in the path of your data.
Your data, yours
Documents, CRM and email are processed on your network. Full data sovereignty, EU-aligned by design.
Built around you
We configure for your workflows, not sell a generic chatbot. Start small, prove it, expand.
Three founders. One mission.
Engineering, operations and the commercial side — under one roof, all three of them hands-on with your project.
Gregor Vider
Company direction and the face of Tavellion. Owns go-to-market, marketing and delivery — and personally leads discovery and your proposal.
Marko Arh
Leads everything technical: the platform, the models and the hardware. Distributed-systems specialist and creator of the Ixian decentralized network.
Matjaž Vider
Finance, pricing and suppliers. Brings a deep DACH enterprise-sales network and the commercial discipline behind every proposal.
Work with the people who build it.
No account managers, no hand-offs. Tell us a problem and the founder team comes back with a plan.
