About Karina Klaassen

Karina Klaassen is a keynote speaker, trainer and leadership expert with more than 30 years of experience in international business, including leadership roles at Unilever. She founded Happibuzz to strengthen what she calls the human core of performance: confidence, ownership and psychological safety.

Organizations rarely fail because of strategy. They stall when capable professionals hesitate under pressure, when teams stop speaking up, and when leaders operate reactively instead of decisively. The hidden cost of low confidence shows up in slower decisions, missed innovation and unnecessary turnover. Her book: Mind your Confidence, Mind your Business, the 7 step Gateway to Happiness and Success addresses the importance of confidence in all areas of our life.

Karina bridges business reality with behavioral science. With an MBA in Organisational Happiness and three decades of leadership experience, she translates neuroscience — including the 7 Rules of the Brain (via Folkerts & Smit) — into practical leadership behavior.

A growing focus in her work is confidence across generations and this is even more relevant now due to AI. Rather than labeling age groups, she helps organizations build shared standards of ownership, accountability and performance.

Do not let Confidence work against you, but FOR you.

In her keynote ‘Building Leaders from Within’, she demonstrates that sustainable leadership starts internally. Leaders who regulate themselves under pressure create teams that take responsibility and deliver results.

Her mission: help people stop waiting for better circumstances — and start creating better results.
