Stéphanie Mazier

What is the common point between marketing, sales, international markets, and gastronomy?

I'm Stephanie Mazier. French by birth, I've called Madrid and Amsterdam home for nearly 20 years, dedicating my career to navigating international markets.

Marketing and Sales have propelled me into top management roles within SMEs. I relish crafting strategies to enter new markets, build strong brands, nurture genuine relationships, and leave a lasting warmth with clients and partners worldwide.

Driven by insatiable curiosity, and learning, I discovered a large range of industries from food and wines to high-tech and e-commerce, to wellness and higher education.

After two decades, I honed my leadership skills with an Executive Master's at EM Lyon, equipping myself with the know-how to drive successful change and transformation within organizations.

Marketing and Sales remain my passions, particularly the thrill of opening new markets from scratch. I leverage these skills to spearhead strategy change and business model evolution, shaping the future of companies eager to thrive in the next economy.

I firmly believe we are transitioning towards a more resilient way of doing business and I am committed to co-creating it with the next generation of leaders.

To have a full picture of who I am, it is important to highlight my love for good food and wines. This passion serves as another compass in my life where I can explore new tastes, concoct recipes, and share memorable moments with loved ones. For me, this is the essence of life.

It is time to deconstruct the box you are fitting in to fully express yourself as a leader and build your company for long-term success reinventing the codes of success.

Steven Jeske

I am Steven Jeske. Born in France, my family's roots have led me to travel and reside in Germany for a significant period. It was there that I discovered and embraced values that define who I am: reliability, attention to detail, and a passion for learning.

Primarily self-taught, I've devoted over a decade of my life to security, transitioning from physical to cyber security. My experience as a systems administrator has showcased my adeptness at solving intricate problems in Systems/Network/Security Administration. 

I'm deeply passionate about the impact of IT on the success of both companies and individuals who leverage it wisely. By focusing on their core principles and reputation, I craft and execute strategies to safeguard and bolster companies, making them more resilient in the face of challenges.

However, this portrayal wouldn't be complete without acknowledging my diverse passions, ranging from highly technical fields such as photography and mechanical engineering to geopolitics.

TERRE INGENIUM is a collaborative initiative born from a desire to drive positive change in business, supporting decision-makers in the practical implementation of their IT strategies. 🌱 From Digital Sobriety to Sustainable Development: I strive to merge performance with ecological responsibility, guiding you towards sustainable and efficient IT solutions designed to anticipate future developments and mitigate obsolescence, all without compromising performance.
