About
The MANAA Family Group INVESTMENTS
An international family enterprise, built on technical rigor, confidentiality and a relentless focus on results.
Our story
From technical expertise to a diversified group
GMI-INVESTMENTS traces its origins to the expertise built by Dr. Eng. Ghassene MANAA over more than nineteen years of international experience in cybersecurity, information systems governance and financial risk management.
That technical and academic expertise gave rise to GMI-TECHNOLOGIES, the Group's first operating subsidiary, before broadening into a wider ambition: a family holding company able to operate and invest across several high-value sectors.
From its headquarters in Muscat, Oman, the MANAA Family Group now carries that ambition across three complementary fronts: technology, real estate and finance, with the same standard of rigor and results that built its reputation.
Mission & vision

To build and grow high-value businesses, operated with an engineer's rigor and governed with an investor's discipline, for the benefit of our clients, our partners and the Group's future generations.
Our vision

Our values
