Learn who Oz’n’gO is
Our values: audacity, creativity, empathy and pragmatism.
What I Do. Who I help.
In a world where a cyberattack or negative publicity can strike in the blink of an eye, internal cohesion and trust become strategic assets.
I created Oz’n’gO to help leaders prepare their teams to react quickly and effectively, to adopt a resilient stance throughout the ecosystem, and to remain vigilant and committed, individually and collectively, no matter what happens.
Who I am.
My background bridges marketing, strategic communication, cybersecurity and tech culture.
I’ve contributed to complex, high-pressure projects such as the State of Geneva’s e-voting platform, the WSIS, which brings together officials and political figures from around the world.
I put my experience at the service of those who want to anticipate and transform their organization to protect the future.
Faced with the explosion of AI and cyber attacks, I rely on a network of experts that I mobilize according to your needs.
Curious? Let’s talk.

Trusted Expertise, Activated When It Matters
I work with a trusted network of experts — in cybersecurity, AI, law, data, and crisis communication.
Activated when it matters most, this collective strength aligns with your priorities and culture to build clear, credible responses — to anticipate, withstand, and rebuild.
Cybersecurity is too often treated as a purely technical issue.
At Oz’n’gO, we see it as a matter of governance, strategy, communication — and preparation.
How do our experts join the game?
Depending on your needs and your level of maturity, experts can step in through:
- A private conversation, to share their perspective on trends and weak signals.
- A focused consultation, to help you frame the right questions on a key issue.
- A targeted audit, to go deeper and assess your situation with clarity.
Each expert has their own terms — rates vary, availability can be limited, engagement is transparent.
Together, we define what makes the most sense, at the right moment.
AI fascinates, disrupts, and challenges our assumptions.
In the corporate world, it reshapes the rules as much as it opens new perspectives.
To stay in control — and not be driven by the unknown — the key is to ask the right questions.
