B2B platform development in Luxembourg

A dense market, and few specialist studios
Luxembourg concentrates a density of financial activity and professional services with no equivalent at this scale: accountancy and domiciliation firms, fund administration, insurance, private banking, law firms, European institutions. These are exactly the professions we have been building platforms for in Belgium for three years.
Local bespoke development capacity, by contrast, is thin: much of the work goes to the large consultancies, at entirely different rates, or to generalist agencies working on themes.
Why our Belgian references are relevant here
A platform for selling accountancy firms designed for the Belgian market answers the same business problem in Luxembourg: a principal who wants to hand over without announcing it, a buyer who wants to evaluate without revealing themselves. The rules differ; the confidentiality mechanics are identical.
Fiderio
selling and merging accountancy firms
Brokeris
selling insurance brokerage portfolios
Skillio
confidential recruitment in accountancy and finance
Multilingual, structurally essential
French, English, German, often Luxembourgish for the public interface. A product aimed at this market cannot be monolingual, and adding languages afterwards degrades performance and URLs. Our architecture builds them in from the design stage, with a clean URL per language.
What we build
Introduction platforms and B2B marketplaces from €35,000. Subscription SaaS products, with plans, trials and automated invoicing, from €25,000. Business applications, client portals and document portals from €20,000.
Data and hosting
Hosting in the European Union by default, a processing agreement detailing locations and sub-processors, logging of document access. For regulated activities, these points are handled at quotation stage, not after launch.
How a project runs
Scoping happens over video, and we travel for the stages that deserve it: the design presentation, acceptance, training your teams. In between, a preview link stays open continuously from the first week — you follow progress whenever you want, without waiting for a milestone meeting. That is how we delivered five platforms in Belgium.

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.
Proof
The work that proves it
Platforms and sites in production, viewable online. No mockups, no invented clients.

Questions
Frequently asked questions
What references can you show in these professions?
Three platforms in exactly these professions: Fiderio for selling accountancy firms, Brokeris for brokerage portfolios, Skillio for financial recruitment. They run in production and can be viewed online — you will judge us on products that work, not on a pitch.
Can you host the data in Luxembourg?
Yes, and it is a frequent requirement in regulated activities. We work with European providers that allow the storage region to be fixed, and the chosen location is stated in the processing agreement.
