The pace of a small team, the rigour of a real engineering studio.
Custom software, shipped to production.
Better than a traditional agency.
We don't resell licences. We build custom software from first principles, and you own everything we ship.
Built to fit, not assembled
Every application, integration and deployment is architected around your actual use case. No white-label SaaS, no recycled template. Built on open infrastructure.
In production within weeks
First working version in one to two weeks. Full project in four to eight weeks. Fixed-price sprints, clear milestones, no scope creep.
Senior engineers, European standards
Team based in Sfax, on Paris time. The expertise you would hire in London or Paris at 40 to 60% lower cost. Working in French and English.
You own everything
Full IP transfer from day one. No vendor lock-in, no licensing traps. Source code delivered, deployed on your own infrastructure. NDAs on request.
Thirty minutes to scope what you need. No commitment, no sales pitch.
What we build
Four practices, one standard: code your own team can pick up, running on your infrastructure.
Business applications
Internal tools, back-offices, client portals.
Built around your actual processes and constraints, not a template. Taking over an existing codebase is an option.
SaaS platforms
Multi-tenant products, from architecture to deployment.
Per-client data isolation, billing, permissions, compliance. Cloud or sovereign hosting.
AI systems and agents
Voice agents, business assistants, multi-agent orchestration.
Wired into the tools you already run, through APIs and MCP. No black box, no single-vendor lock-in.
Nearshore team extension
Senior developers working inside your process and your Git.
On Paris time, in French or English. Staffed within five days, scaling up as the work grows.
Work
Projects running in production. Clients anonymised, technical scope real.
SaaS vendor, leisure and sport
Multi-resource booking engine, point-of-sale checkout, NF525 fiscal compliance, e-invoicing and Stripe payments.
Multi-site network, services
Voice agent handling inbound calls around the clock: qualification, routine questions and booking written straight into the business calendar.
Where we deploy
Three markets, one engineering posture: production-first, no black boxes, no lock-in.
Our process
From audit to scale, a proven path to production AI.
Audit & Discovery
We analyze your existing workflows, identify automation opportunities, and map the technical stack.
Architecture
Multi-agent systems engineered from first principles. No black-box SaaS, no vendor lock-in.
Deployment
Seamless integration into your infrastructure. Docker Swarm, Laravel Observer, MCP Protocol native.
Monitoring & Scale
Real-time performance, automated scaling, continuous optimization of your agent fleet.
What SMEs ask us most
Straight answers before you launch your AI agents project.
A multi-agent system is an architecture where several specialised AI agents (a planner, workers, tools) collaborate to run a complex task end to end. SIFO orchestrates these agents with Claude, the Model Context Protocol (MCP) and observability to automate full business processes, not just answer a single question.
