And then, decades later, they realized those four paths had built something almost no industrial group can match: the complete value chain, under one family roof, across three continents.
The Ronen brothers were not raised to build a holding company. There was no master plan, no family office strategy, no inherited industrial empire. Each brother chose his own discipline, picked his own city, and built his own career — independently, in different countries, in different industries.
Yariv, the eldest, trained as an engineer and served as a Naval Officer in the Israel Defense Forces. He moved to Prague and spent more than two decades building one of the city's leading residential developers — delivering 4,500+ apartments and shaping entire neighborhoods on the Vltava River.
Itamar, the second, became a mechanical engineer at the Technion and joined Israel's defense industry. Over thirty years he rose to lead engineering teams at Elbit Systems Land Division — designing platforms, propulsion, and integrated mechanical systems to military and aerospace standards.
Ori, the third, began his career in the Israeli defense industry alongside Itamar. Seven years ago he moved to Pune, India, and became CEO of Gevasol Industries — an Israeli-owned, AS9100D-certified manufacturer of BLDC motors for aerospace and defense — growing it from a small production line into a multi-dozen-employee operation.
Hagi, the youngest, trained as a geoinformation engineer and joined Israel's national mapping agency as a student. In 2021 he became its youngest-ever Director General, leading the establishment of location-based platforms and services for decision-making — serving the government, local authorities, the third sector, and the public — and growing the agency through innovation, technology, and cross-sector partnerships.
Over years of family conversations — at weddings, at holidays, on long phone calls between Prague, Tel Aviv, and Pune — a pattern emerged. Each brother had become a leader in something the others didn't do. None of them was competing with the others. All of them were pieces of a larger picture none of them, alone, could see.
When you put the four pieces together, the picture is unmistakable:
Capital. Engineered. Manufactured. Delivered.
Most industrial groups have to assemble a leadership team capable of all of these. Rosenman has it by birth.
The world has changed in ways that play directly to our strengths. Industrial supply chains are being redrawn — between East and West, between Europe and Asia, between defense and commercial sectors. Companies need partners who can move capital across borders, design to military standards, manufacture at aerospace quality, and overlay it all with modern digital and AI capabilities.
Rosenman was created because our family already operates in every one of those layers. We are not building this from scratch — we are formalizing what already exists, and offering it as a single capability to the world.
Our standard is simple: if a Ronen would not be proud to put his name on it, we don't ship it. One signature. Four brothers. Three continents. One standard of excellence.
Each capability is led by a brother — accountable, reachable, with skin in the game.
