We do not sell one piece of software: we put together the ones that fit your needs, starting from those you already have. Here is how they fit, from the AI model down to your website.
The connections
MCP servers give AI controlled access to your software; n8n chains the repetitive tasks, with or without AI.

The open-source CRM that fits your business without development, and whose bill does not climb with every hire.

The workflow engine that connects your tools, on your server, with no per-operation bill and AI only where it helps.

The technology behind our sites: ready-to-serve pages, fast and secure, that the whole team edits without a developer.
Web analytics hosted by you: your visit figures, without handing your visitors’ data to a third party.
Open AI models, hosted by us or by you, for tasks whose data must not leave.
The ERP that brings sales, invoicing, projects and accounting together, set up in three fixed-price tiers, from €15,000.
The light open-source ERP: quotes, invoices, inventory and projects in one place, for teams of 5 to 50 people.
The standard that connects AI to your software: CRM, ERP, shop, documents. Less typing, less back and forth between screens.
Anthropic’s AI that we deliver our projects with, and that we teach your teams to use safely.

The ready-to-sell e-commerce platform, which we configure, enrich and grow without losing its search rankings.
