Hands-on support
Hi, I’m Roy! I’m the CEO of Sizer and the creator of the HandClap decision-making method. Over the past 25 years, I’ve built my career leading international teams, scaling startups, and driving business development across Europe, the U.S., and Israel.
I know what it feels like to face tough choices as a leader, entrepreneur, or professional trying to grow. That’s why I combine my background as a CEO, entrepreneur, and certified mental coach to help mentees like you gain clarity, confidence, and direction.
Whether you’re working on scaling a startup, navigating corporate leadership challenges, or trying to position yourself with impact, I’ll bring you practical strategies, honest feedback, and frameworks that actually work. My mission is to help you move from doubt to decision, from idea to execution — and make sure you don’t walk the journey alone.
