rouage designs and builds AI-powered process and service applications for your business — developed with frontier AI, reviewed and hardened by security consultants.
You bring the process; we build the application. Every engagement pairs frontier AI development speed with the review discipline of a security practice.
Connect AI safely to the systems you already run — CRMs, ticketing, data stores — with least-privilege access and auditable behavior.

learn more → 03_automationTurn repetitive business processes into reliable automated pipelines: intake, triage, reporting, document handling, and approvals.
learn more → 04_assuranceAI-generated code, reviewed like it matters. Threat modeling, dependency and supply-chain checks, and hardening before anything reaches production.
learn more →There’s no fixed list. We build with frontier AI, and its language coverage comes from training on the world’s code — not per-language integrations. So it tracks the whole ecosystem. Here’s how the depth breaks down:
Legacy and niche languages count too — Fortran, COBOL, Ada, Prolog, Lisp, Tcl, Nim — with depth proportional to how much of that code exists in the world. And every language above gets the full treatment: written, debugged, refactored, reviewed, translated, and shipped with tests that actually run.
Three phases, in order. The order is the point — security isn’t a final step, but hardening has one.
We sit with the people who do the work, map the current process, and agree on what the application must do — and what it must never do.
Working software early and often. AI-assisted development means days to a working prototype, not months — with you reviewing real builds weekly.
Security review, access controls, monitoring, and a handover your team can actually maintain. Then it ships.
rouage (pronounced roo-AHZH) is French for the gears of a mechanism — the working parts that make the whole thing run. It’s what we build: the AI machinery inside your business processes.
rouage is the development practice of verrou, a security consulting firm. That heritage isn’t branding — it’s the operating model. AI can write software faster than anyone can review it, which is exactly why every rouage build goes through the same scrutiny we’d apply to a client’s production systems.
verrou locks things down. rouage makes things run. Same hands, both jobs.
A thirty-minute call is enough to tell you whether AI is the right tool for it, roughly what it would take to build, and how we’d secure it.
