Direct peers

• John Kotter: Pioneer of change management theory (8-Step Process), Harvard professor emeritus, and keynote speaker on leading organizational change. Directly comparable in content niche (organizational change) and in monetizing proprietary methodology through speaking and consulting.
• Dave Ulrich: HR and leadership thought leader, author of over 30 books, and frequent keynote speaker at HR events (HRcoreACADEMY-style). Direct overlap with Cyriel's primary HR/L&D buyer segment and speaking-circuit presence.

Closely comparable business model: solo practitioner, premium fees, proprietary behavior-change methodology, Fortune 500 clients.

• Brené Brown: Research professor and globally recognized keynote speaker on leadership, courage, and vulnerability. Comparable business model at a much larger scale — premium fees, bestselling books, Netflix special — and overlaps with Cyriel's leadership/change audience.

Emerging players

• Ethan Hadley: Executive coach and change-management speaker with a similar European footprint and target audience. Comparable as a smaller-scale solo practitioner in the same change-leadership niche.
