HOLDING COMPANY · ROTTERDAM
Long-term stewardship for
Moon-to-Earth innovation.
4 OMID B.V. is the personal holding company of founder Omid Hajishirmohammadi and the parent company of 4 Earth 2 Mars Holding B.V.
Based at BlueCity in Rotterdam, 4 OMID provides long-term ownership and stewardship for the founder’s entrepreneurial work. Its principal operating focus is expressed through 4 Earth 2 Mars, which develops CATs&DOG® and advances a Moon-to-Earth approach to construction innovation.
PURPOSE AND STEWARDSHIP
A stable foundation for
long-term entrepreneurial work.
4 OMID exists to provide ownership continuity and long-term stewardship behind the founder’s entrepreneurial activities.
4 OMID is not the public-facing technology or project brand. It provides the corporate foundation behind 4 Earth 2 Mars, allowing the operating company to focus on CATs&DOG®, technical development, partnerships and Moon-to-Earth construction innovation.
This structure separates long-term ownership and stewardship from day-to-day development activities while keeping the founder’s purpose, responsibilities and company interests aligned.
