Sustainable performance starts with people and cultures.

Business success is not only driven by technology or capital but by what matters most:
people, cultures, and purpose.

Kyllen Consulting supports leaders and international organizations through high-impact keynotes and advisory services, at the intersection of cross-cultural excellence and sustainable performance.

Our services

Two complementary levers to act fast with impact.

Keynotes

Designed to reveal intercultural frictions, rapidly align leadership teams, and strengthen collective effectiveness in international contexts.

Formats : Executive Committees - Managers - Seminars

Advisory

From diagnosis to roadmap, we structure your ESG/CSR priorities and multicultural dynamics to secure execution, governance and internal adoption.

Formats : C-level / Executives workshops

What slows down your performance without always being visible

- Slower decision-making in multi-country organizations
- Weakened cooperation between headquarters, subsidiaries and partners
- Recurrent misunderstandings, implicit tensions, managerial fatigue
- ESG/CSR transformation perceived as "separate" from core business
When these frictions take hold, they become structural, cost time, energy, and execution.

An approach focused on impact, alignment, and execution

- Clarify the cross-cultural mechanisms that block decision-making and action
- Create a shared framework for communication and cooperation
- Reconnect sustainability and performance: priorities, steering, adoption
- Secure multi-stakeholder transformations over time

For international and multicultural organizations

- Cxo and Executives committees: alignment, execution speed, multi-country governance
- HR / Talent / Learning: management effectiveness, engagement, cohesion
- ESG/CSR: strategy, steering, internal adoption
- France Africa stakeholders: projects, partnerships, subsidiaries, ecosystems

"Keynotes reveal. Advisory transforms.
My objective: to make intercultural excellence and sustainability tangible levers for performance and impact."
