Abdulhai Hejazi
Investor. Chairman. Builder of businesses that last.
Chairman & CEO of Technical Dimensions Co. Angel investor in companies reshaping Saudi Arabia priority sectors real economy.
About
For over 17 years, I have built and scaled Technical Dimensions Co. (TDCO) from a single project into a construction and real estate development firm operating across all 13 regions of Saudi Arabia. That journey taught me how capital, operations, and timing intersect in emerging markets.
Today, I deploy personal capital as an angel investor into early-stage technology companies reshaping sectors I understand operationally. Real estate, infrastructure, F&B, and financial services are where I focus. I back founders who see the same opportunities I see in a region transforming under Vision 2030.
My approach is hands-on. I bring operational experience, regional networks, and patient capital to the founders I support. I am not looking for quick exits. I am looking for businesses that last.
What I Back
Vision 2030 Enablers
Companies operating inside Saudi Arabias priority sectors. Fintech, proptech, and F&B technology, where national policy and capital flows align.
Tech Transforming Real Economies
Technology that reshapes sectors I understand operationally. Construction, real estate, finance, and retail, not pure software speculation.
Cross-Border Conviction
Selective bets that bridge Saudi capital with adjacent markets, including Syria emerging digital infrastructure, where regional roots create unique conviction.
