Strengthening gender balance, transforming leadership models
For over 15 years, Diafora has been supporting companies committed to increasing gender diversity within their teams and driving long-lasting transformation in their managerial culture.
Founded in 2008 by Véronique Préaux-Cobti, Diafora has developped an international expertise working closely with organisations to foster a more inclusive, gender-balanced, and high-performing culture at all levels.
In close collaboration with executive committees, we combine tailored support with a collective vision, enabling leaders to align governance and strategy around gender balance—a key lever for attractiveness, innovation, and performance.
Our actions
Supporting transformation
We work alongside governance bodies, HR teams, managers, and talent, tailoring our approach to each company’s specific challenges, markets, cultures, and level of maturity.
Developing talent
Our cross-company programs support women at every stage of their careers, as well as young talent and managers in mixed-gender tracks, helping them strengthen their leadership and build strong international networks.
Creating lasting impact
Through workshops, training, and global action plans, we help make gender balance a cornerstone of cultural transformation and the renewal of leadership models.
“Because gender balance is now one of the key conditions
for collective intelligence and sustainable performance.”
