AI, all the way to production

We build AI into your applications and into the way your teams build software, to the same standard as the rest of your system.

In your applications

Agents inside your systems

  • Assistants that answer from your documents and cite the source of every answer.
  • Agents that act in your tools (ERP, CRM, ticketing) through MCP connectors, with the user’s own permissions. A person approves anything that commits the company.
  • Semantic search across your databases and documents.
  • The model of your choice: Azure OpenAI, OpenAI, Anthropic, Microsoft Foundry or an open model hosted on your premises.
  • Every action logged, costs tracked, and your data kept where you decided.
Example: an agent prepares a reminder for three invoices, and accounting approves sending it.

In your engineering

The agent writes, the architect decides

  • We deliver with coding agents: more releases, held to the same standard of testing, security and accessibility.
  • Nothing reaches production without an architect’s review.
  • We set up this way of working in your teams: repository conventions, instructions and skills for the agents, and automated checks before every merge.
  • We train your teams on their own projects.
Example: an agent delivers a change, and the architect approves it before it goes to production.

What we refuse

  • A prototype with no path to production.Every use case starts with its architecture, its costs and its route to production.
  • Data that leaves without your consent.You choose where the models run and what they see.
  • Code that nobody has reviewed.An architect reviews and approves every release to production.
  • Lock-in to a single model provider.Your applications switch models without being rewritten.
