As part of the WomenTech Global Conference 2025, Sanofi opened its doors in Barcelona for an extraordinary evening dedicated to celebrating and empowering women in science and technology. Themed “Women in STEM Leadership,” the event invited attendees to explore the journeys that shape impactful careers—not through perfect plans, but through real experiences, unexpected turns, and the courage to lead without all the answers.
Honest Reflections and Shared Perspectives
The evening began with an introduction from WomenTech Network and Sanofi, setting the tone for a deeply personal and inspiring session. This wasn't a lecture or a checklist for success. Instead, it was an opportunity to pause, listen, and connect—with the stories behind the titles, the people behind the progress.
In a compelling panel moderated by Andrea Macarie, Communication Business Partner at Sanofi Spain, five incredible women shared how their careers unfolded across different corners of the STEM world:
-
Marta Diez, General Manager Sanofi Vaccines Iberia
-
Elisenda Vives, Digital and Cultural Transformation Lead at HP
-
Mayra Arnau, Head of Post Market Quality Digital Solutions - Executive Director at Roche Diagnostics
-
Mariona Sanz, Head of Innovation at BSC (Barcelona Supercomputing Center)
-
Montse Daban Marín, Director of Strategic Foresight and International Relations at Biocat

Leadership with Purpose
The event wasn’t just about where these women had been—it was about how they lead today and what they believe the future of STEM should look like. From navigating complex decisions to nurturing inclusive teams, the panelists emphasized that leadership grows from experience, vulnerability, and the support of others.
And as Sanofi unveiled its newly launched Digital & AI Hub in Barcelona, the message was clear: for those seeking work that matters, this is a moment to step forward. With over 300 roles across data, technology, and science, the hub represents both an invitation and a statement—innovation and inclusion can go hand in hand.
"I had the chance to attend the in-person WomenTech session at Sanofi Barcelona. It was so insightful to be in the room with such amazing women on stage, each bringing their own experiences, challenges, and lessons. Feeling energized, grateful, and proud to be part of a company and a global community that celebrates and drives inclusion, innovation, and impact." - Vanessa Estorach Cavaller, Digital Business Transformation Senior Lead, Digital Manufacturing and Supply at Sanofi.
"It was truly inspiring to hear those strong women leaders share their journeys with honesty and passion. Their words reminded me of the power of visibility, community, and support among women. Each story highlighted how resilience and authenticity can break barriers.
The atmosphere was electric with authenticity and connection, a space where women uplifted each other with purpose. What stood out was the genuine sense of community; it wasn’t just about leadership, but shared growth and support. The event created a ripple of empowerment that will stay with everyone who attended. It felt local, personal, and deeply impactful.
I left the session feeling empowered and motivated to keep lifting others as I climb." - Ariadna Trueba, Chapter Leader of Barcelona at WomenTech Network
"Today at Women in Tech in Barcelona, it was special to connect and see the important questions kept alive! Women are changing the work environment with the wisdom only we have. Personally, what touched me the most was one discussion about strength, and all its kinds. That thought alone is already unique!
Strength is also resilience, is also adaptability, influence, and persuasion. Strength can also be a smile! And empathy, and listening, and perception, and courage! Women, in tech or anywhere, are a force." - Anna Rinaldi, Ads Performance Manager at Amazon
A huge thank you to Sanofi for not only hosting this event, but for their unwavering dedication to reshaping the future of healthcare. The stories shared were a testament to the power of community, resilience, and leadership that lifts others.
A special note of appreciation to our Barcelona chapter leader, Ariadna Trueba, whose dedication and vision continue to inspire and connect women across the STEM ecosystem.
