My work started with the internet and entrepreneurship in the 1990s. Since then, I have co-founded several companies, helped build Kima Ventures, and invested in hundreds of startups across many countries. These experiences shaped how I think about ambition, risk, timing, partnership, responsibility and resilience.
For current investment activity, startup-related inquiries, fund strategy and venture capital work, the right destination is Magical Capital. Berrebi.org remains my home for personal reflections and selected writing.
I have always been a technology geek: fascinated by products, networks, interfaces, infrastructure and the way new tools reshape human behavior. From the early Internet to today’s AI revolution, I have kept the same curiosity for how technology creates leverage, changes habits and allows small teams to build things that once required large organizations. Over the years, I have also had the privilege of being involved, as an investor and cofounder, with many companies that became leaders in their industries.
I am deeply attached to Torah and Talmud study. Judaism is not a side topic for me; it is a living framework for responsibility, time, family, community, meaning and the challenge of staying human in a distracted world.
I am also a husband, father and grandfather. That matters because it changes the scale of everything: what is worth building, what is worth saying, what is worth passing on, and what kind of life is actually successful.
