Your own Assistant. On your hardware.
Tavellion builds Avellion — your company's AI assistant, running on a server inside your building. It learns your business and runs your work, and your data never leaves your network.
Not sure where to start? Book a discovery video call — we'll scan your company and come back with a proposal.
On your hardware
Avellion runs on a server in your own building. You hold the keys to the machine, the model, and the data. Nothing is outsourced to a third party.
Your data stays yours
Documents, CRM and email are processed on your network. Your contracts and customer data are never uploaded to another company's servers.
No meter you can't read
A frontier chatbot bills you by "usage" — the more you use it, the more you pay, but you can't actually see how much more. Avellion has a fixed cost: it gets cheaper the more your team uses it.
Everything runs where your business runs.
Your team talks to Avellion. Avellion thinks on a model sitting on your hardware. It works your tools. That's it — there's no third-party cloud in the loop.
You bring the problem. Avellion does the work. You keep the call.
Here's how a task actually divides once your Assistant is in. Most of it stops being your hours — it becomes his hours.
You frame the task — the goal, the context, what "done" looks like. A sentence, a pointer, a set of constraints. Once.
It pulls the data, reads the documents, drafts the proposal, runs the workflow, fills the forms, assembles the report. The bulk of the hours live here — on your hardware.
You read it, adjust what matters, and approve. It never sends anything external without your go-ahead.
From "we have a problem" to a working Assistant.
We don't sell off-the-shelf software. We start from your company, not from a product page.
Scan
A discovery call plus a short look at your processes and data. We map what's worth automating.
Proposal
Which workflows, on what hardware, what it changes for your team. You approve before we build.
Deploy
We set it up in your building, connect your tools, and train your team to run it — then it works 24/7/365 for you.
One Assistant your whole company actually uses.
Avellion plugs into the systems you already run — chat, email, files, CRM — and works on the tasks that eat your day. It remembers context, follows your processes, and answers from your own data.
Knows your business
Indexes your documents, CRM and email so it answers from your data — with sources, not guesses.
Drafts in your voice
Proposals, decks, emails and reports, drafted from your templates and past work.
Runs your workflows
Repetitive, multi-step work — pulling data, filling forms, preparing reports — becomes a thing it just does.
Works when you don't
Available 24/7/365. It keeps context across sessions and asks before acting on anything external.
The workflows we build for companies.
Four that pay for themselves — each running on your hardware, on your data. We start with the one that hurts most.
Knowledge assistant
Ask a question, get a sourced answer across all your internal documents, files and email.
Sales agent
Researches prospects, drafts tailored proposals, pitch decks and follow-ups in your voice.
Support assistant
Consistent answers from your own knowledge base, in your language, whenever a customer writes in.
Ops & automation
Pulls data across systems, fills forms, prepares reports and runs the recurring jobs.
The best AI for your company is the one that runs where your company runs.
A frontier cloud chatbot is powerful — but it works on your data only by first sending it out to someone else's servers. We build the alternative: a senior, founder-led team, EU-based, that deploys an Assistant your company actually owns, and keeps it working 24/7/365.
