More about Sylvain

Dr. Said Oualibouch founded REVARTIS in 2010. He works with the leadership of regulated organizations — in financial services, digital health, public sector, and telecommunications — on their most consequential technology and transformation decisions.

His career began in research. A doctorate in Applied Mathematics and Computer Science, followed by two decades building and leading capabilities across engineering, governance, revenue assurance, and enterprise architecture, gave him something that strategy alone cannot produce: a precise understanding of why organizations fail to perform at the level their resources and ambition would suggest — and what it actually takes to change that.

The diagnosis is rarely where clients expect it. The constraint is almost never technology. It is the misalignment between strategy, architecture, governance, and the people responsible for making all three work together. Addressing that misalignment — structurally, not symptomatically — is the core of his practice.

Over the past five years, the AI transformation programs he has led have consistently delivered positive ROI within six months. Several have exceeded €20M in the first year. That consistency reflects a discipline his clients come to recognize: every transformation is an expression of a strategy. Organizations that lead with technology, before that alignment is in place, reliably waste capital and lose momentum.

At REVARTIS, he works as a trusted advisor to executive committees and boards — structuring AI transformation roadmaps, governing their execution, and ensuring that what is built delivers lasting organizational capability, not isolated pilots. Depending on what the situation requires, he engages as Strategic AI Advisor, as Fractional CAIO, Transformation Architect, Program Director, or as an independent voice on the steering committee of major programs.

Holding a PhD in Applied Mathematics & Computer Science from Université Grenoble Alpes and an Executive MBA in ICT from the University of Fribourg, he operates in full alignment with revFADP, EMBAG Article 9, and the EU AI Act.

Dr. Otmane Azeroual began where all durable innovation begins — in research. Trained as a scientist, he developed methods, models, and architectural concepts in data management, information systems, and AI that were rigorous enough to publish and practical enough to deploy. That combination — scientific depth in service of operational impact — has defined every role he has held since.

His career spans international engagements across private industry, federal administrations, and research institutions — as Senior Project Manager, Strategic Technology Advisor, Scientific Director, and at CTO level. Across all of them, the challenge was the same: how do you take data and AI from controlled environments into organizations where scale, security, governance, and human complexity make everything harder? His answer has always been architectural — build the right foundations, design the right flows, and the intelligence follows.

At REVARTIS, Dr. Azeroual leads AI Research & Development Services — the practice responsible for translating the firm’s transformation vision into intelligent, sovereign, and scalable platform architectures. He works at the intersection where data strategy meets system design, where governance frameworks meet operational reality, and where research-grade rigor meets the pressure of production environments.

His focus is the architecture of organizational intelligence: designing the pathways through which data flows, decisions form, and AI-driven value becomes real and repeatable — not as isolated pilots, but as living systems embedded in the organization’s core. He accompanies clients from strategic conception through governance design, platform architecture, and full operational deployment — ensuring that what is built does not merely function, but endures.

At REVARTIS, his work is the technical embodiment of Assist to Thrive — engineering AI systems that strengthen what organizations and their people are capable of, rather than bypassing the human judgment that sustains them.

Robert Ledwig is the engineer who makes AI transformation real.

Strategy defines the direction. Architecture designs the system. Robert builds the thing that runs — from first prototype to production deployment, with the reliability and precision that regulated environments demand.

A Systems Engineer with over ten years of experience, his background spans domains where software failure is not an option: safety-critical embedded systems certified to ISO 26262 and IEC 62304, financial technology platforms, and modern full-stack product architectures. That range is not accidental. It reflects a discipline — the ability to hold rigorous engineering standards and delivery velocity simultaneously, without sacrificing either.

At REVARTIS, Robert leads Software Engineering Services — the practice responsible for translating AI strategy, governance frameworks, and architectural decisions into working, production-ready systems. He designs and implements AI-powered workflows, automation pipelines, and product platforms that move directly from concept to deployable outcome. His measure of success is simple: does it run, does it scale, and does it deliver what the transformation promised?

In a firm where every engagement is accountable to measurable outcomes, Robert is where accountability becomes concrete.
