Founders

Two perspectives, one shared standard: make data useful—without compromising trust.

Stelliane was born from a simple belief: data creates value only when it’s understood, reliable, and protected. Laurence and Yann built their careers around that standard—bridging business, IT, and compliance—before creating a firm designed to move fast without cutting corners.

Today, GDPR is a complex topic that many companies handle “by default,” without always knowing what is truly in place—what gets activated, what data is collected, and what is kept. A corporate website is often the first point of exposure, because it instantly reflects an organization’s level of compliance maturity.

In many cases, a CMP banner is implemented, but marketing tools keep piling up (analytics, pixels, tags, and more), while configurations—and their real effectiveness—are rarely tested. The result: hidden compliance gaps, a false sense of safety, and growing risk.

And the risk of enforcement action from the CNIL or the DGCCRF keeps rising—along with the direct impact on brand reputation.

Laurence has developed expertise where data becomes truly critical: when it involves people, businesses, and accountability. Her guiding principle is simple: make compliance practical and security easy to understand, so teams can take action instead of feeling overwhelmed.

At Stelliane, she brings a proactive approach: identifying and clarifying risks, prioritizing actions, and building lightweight frameworks that work in day-to-day operations—not just in policy documents. The result: faster decision-making, safer practices, and compliance you can stand behind.

Yann grew his expertise in environments where data must be both robust (technically) and actionable (for business). He enjoys tangible topics: master data (MDM/PIM), quality, tooling, architectures, and roadmaps.

His focus: foundations that are reliable, readable, and evolvable—so teams can accelerate delivery and reduce friction, without piling up unnecessary complexity.

What guides us

Our belief: you can’t protect what you don’t understand—and you can’t sustain value without governance.
