Where we are, and how we work
Scoping happens over video, and we travel for the stages that matter: design, acceptance, training. In between, the preview environment stays open continuously.

Professions we already know
Geneva and Lausanne concentrate private banking and family offices, commodity trading, accountancy firms, law firms, private clinics, the EPFL ecosystem and a large number of international organisations. The five platforms we have delivered in Belgium belong to the same professional families: insurance broking, accountancy firms, real estate, financial recruitment.
The technical requirement is identical — graduated confidentiality, role-based access, subscriptions, multilingual — and that is precisely what we build.
Data location, handled at quotation stage
This is the point most foreign suppliers dodge, and it is often decisive for a bank, an accountancy firm, a law firm or a clinic. The revised FADP imposes a strict framework, and your clients will ask where data is stored.
We offer hosting in Switzerland, with Swiss operators, under a processing agreement that names locations and sub-processors. Failing that, the European Union by default. That choice is in the quote, not in a conversation after launch.
What we build
Introduction platforms
and confidential marketplaces, from €35,000
Subscription SaaS products
with plans and automated invoicing, from €25,000
Business applications and client portals
with role-based access and logging, from €20,000
Bespoke multilingual sites
from €9,000
Our pricing position
We invoice in euros, at French market levels. For an equivalent project the gap against a local agency is substantial, without any change in delivery quality: same team, same performance standards, same contractual commitments. We are not trying to be the cheapest on the market, because too low a price does not signal a good deal.
How a project runs
Scoping happens over video, and we travel for the stages that matter: the design presentation, acceptance, training. In between, a preview link stays open continuously from the first week, and you talk directly to the people designing and building — not to a project manager in between. That is the way of working that let us deliver five business platforms.

Why us
What sets us apart
Four commitments that hold over time, not four slogans.
100% code, zero proprietary platform
No WordPress, no Shopify, no page builder. Your product is written in TypeScript, documented and version-controlled — the repository is yours from day one, and you are locked in to nobody.
Products, not brochures
User accounts, recurring subscriptions, messaging, gated access, payments: we have shipped five platforms running with real paying customers behind them.
Regulated sectors
Insurance broking, accountancy firms, real estate, financial recruitment. We know the data confidentiality, role-based access and domain constraints these professions carry.
Multilingual by default
FR · EN · ES. Internationalisation is built into the architecture, not bolted on as a plugin six months later — essential in Belgium, Luxembourg and Switzerland.
Questions
Frequently asked questions
Can you host the data in Switzerland?
Yes, with Swiss operators. The chosen location and the sub-processors are named in the processing agreement, so that you can answer your own clients and your compliance function.
Do you invoice in Swiss francs?
We invoice in euros. For a Swiss company the service is outside the scope of French VAT; the import of services is declared according to your local obligations, which your accountant will confirm.
What happens if we change supplier?
You pick the project up without rewriting anything. The code repository is yours from day one, the handover documentation ships with it, and we support the transfer. That is the most concrete guarantee we can give: you are locked in to nobody, including us.
