Platforms, SaaS and AI-built apps, shipped to production

For startups, companies and agencies: custom platforms and SaaS, integrations, and apps built with Lovable, Cursor or Claude Code, finished and shipped. The same team has run a financial portal serving 24M users a year.

What we have operated

24M
users a year on a financial portal
30,000
employees using internal tools we built
40M
records migrated with no data loss

Enterprise work is covered by non-disclosure agreements and is described without naming the client; we go into detail in a meeting. Our own products - DameTicket, InteliFactu, ZoneMirror and this site - are public and testable.

What we do

Five ways teams bring us in

Always the same contract: the server decides, the client renders, and performance has a budget.

Custom platform development

TypeScript, React and Next.js on managed infrastructure, with business rules resolved server-side.

SaaS products

Tenant isolation, role-based access and recurring billing treated as server state, not as a webhook.

Integrations and data migration

40M records moved with row-level verification and a rehearsed rollback plan.

Rescuing stalled projects

Audit first, freeze behaviour, then refactor by area. Full rewrites only when keeping it costs more.

Vibe code rescue

AI-built apps finished, hardened and deployed: Lovable, Bolt, v0, Cursor, Claude Code, Codex.

Photography, video, graphic design and marketplace listings support these projects, but they are not our main work and have no page of their own.

Pricing

Prices published before the first call

Almost nobody in this market publishes prices. We do: if the budget does not fit, it is better to know now. The fixed quote comes out of the scoping session.

Custom platform or SaaS: From EUR 12,000; When the software is the business: internal dashboards, ERP integration, recurring billing, several user roles.
AI-built app rescue: Audit EUR 450; Delivered within 48 working hours and deducted if you continue. The rescue is a fixed-scope quote, typically EUR 1,500 - 6,000; we finish your app, we do not rebuild it.
Online store: EUR 4,000 - 12,000; Catalogue, payment gateway, stock and shipping. Custom when the sales process does not fit a template.
Corporate site: EUR 1,500 - 4,000; A fast site, contact form, analytics and technical SEO.

White label

We also work for other agencies

Design studios, marketing agencies and consultancies that sell more development than their team can build. We deliver under their brand, sign a non-disclosure agreement when they need one, and talk to their client only when they ask us to.

What we usually take on

Custom platforms and SaaS, online shops, WordPress and PrestaShop, integrations, data migrations and infrastructure. A fixed phased quote you can put your margin on, one point of contact and the same process as a direct engagement.

How we work

Four steps, no surprises

The same process on a three-week engagement and on a two-year platform.

01
Scope
One session to understand the business process, not to show templates. We leave with priorities and a phased price.
02
Architecture
Data model, integrations and a performance budget before the first screen is written.
03
Build
Weekly releases to an environment you can visit. What gets approved gets deployed, it does not pile up.
04
Operation
Monitoring, verified backups and deployments anyone on the team can run.

How we explain it

Explained in your language, not in ours

You do not need to know what a deployment is. You need to know what each phase does, what it costs and what happens when something breaks. When a technical decision affects your business, we explain the trade-off and you make the call.

Next step

Tell us what the system has to do

We reply within one business day with a phased scope proposal, or with the reason we are not the right studio for it.
