01 What we do

We develop with AI.

Scope

week 01

A week with you, to cut the idea down to the version worth building first. You leave with a plan and a number.

Build

weeks 02–04

By week 2 you're already clicking it, on real data. Then we build the actual product: app, backend and infrastructure by senior engineers, hosted in Switzerland.

Hand over

week 05+

Code, docs and a walkthrough, so your team can extend it without us. No black boxes, no lock-in.

05 Questions

If you have more questions.

What is Mont3?

Mont3 is a Swiss AI development studio in Lugano. We build startup products in four-week cycles, AI agents that automate internal workflows, and local AI that runs open-weight models on your own hardware, so company data never leaves the building. We work with startups and SMEs across Switzerland and Europe. The team is senior-only: the people on the first call are the ones who write the code, and you keep the source and run it without us afterwards.

How much does an AI project cost in Switzerland?

We publish what is fixed: a custom web app built with AI starts at CHF 10'000, a scope we used to quote at three times that, and local AI installs on your own machine start at CHF 3'500. Every build is scoped in week one, and you leave scoping with a concrete build plan and a number, before committing to anything.

How does “if it doesn't work, you don't pay” work?

During scoping we agree in writing what “working” means for your build: the concrete things the software must do at delivery. If what we hand over doesn't do them, you don't pay for the build. The definition is fixed before we start, so there is nothing to debate after.

Can AI run entirely on our own machines, without our data leaving the building?

Yes. We install open-weight models on hardware you own: private, offline-ready, with a chat interface for your team. Nothing is sent to a cloud provider, which is what makes it workable for fiduciaries, finance and healthcare.

How long does an AI build take?

Four weeks is the standard cycle: scoping in week one, a real prototype on real data by the end of week two, production deploy in weeks three to four, then handover, code, docs and a walkthrough, until your team can extend it without us.

Who do you work with?

Three kinds of clients: startups that need a first product built, SMEs that want AI agents and automation in their workflows, and regulated teams, fiduciaries, finance, healthcare, where data must stay in the building.

Do we own the code?

Yes. Code, documentation and accounts are yours at handover. No black boxes, no vendor lock-in, and pre-existing Mont3 tooling never holds your product hostage.
