Paris · Software & agentic systems
MAINFRAME designs, builds and runs business platforms and AI agents for companies that depend on them every day: from the data model to the server it lands on.
01 / Services
ERP, CRM, HRIS and internal tools shaped around how your company actually works.
AI agents that listen, reason and act on your real systems, with the guard-rails of production software.
Cloud, CI/CD, security and monitoring, so what we ship keeps running after launch.
02 / Live
An agent reads, checks against your systems, acts through tools you allow, and hands anything uncertain to a person. Every step is logged.
03 / Approach
Most of our clients don't have a product owner or a product manager. We fill that gap: we sit with the people who run the business, understand how it really works, and carry the project from the first conversation to production.
The business logic, with the people who live it.
Requirements and architecture documents everyone signs off.
Data model, API and screens.
Back end, front end, database and tests.
Servers, CI/CD and monitoring, then ongoing support.
New · Pilot programme open
