Studio
A studio that owns the whole problem.
MAINFRAME is a software studio based in Paris. We build the systems companies run on (ERP, CRM, HRIS, operations tools) and the AI agents that now work alongside them.
We take responsibility for the whole problem: the architecture decision, the specification that explains it, the code, and the server it runs on. One team from the first workshop to production, then still there afterwards.

Principles
Own the whole problem
From business logic to deployment, nothing falls between two contractors.
Agents are production systems
Contracts, tests and observability, the same as any other code.
Specs are part of the product
Every decision is written down and signed off, so the system outlives the project.
Your data, your system
EU hosting by default, documented hand-over, no lock-in.
Have a system to build?
A platform, an agent, or both. Tell us about it.
