About Sustainari
Founder & CEO
M. Eng. Akram Ezzat
Energy Efficiency Expert · Engineer · dena-listed
As an engineer with many years of industrial experience, I know the challenges of technical systems from practice — not just from textbooks.
Sustainari was founded on the conviction that energy efficiency and economic viability are not contradictory. Through data-based analysis, engineering expertise and long-term support, I help companies and homeowners reduce energy costs measurably and sustainably.

From the Workshop to the Office
Akram Ezzat began his career as a tool mechanic — with a wrench and caliper, not PowerPoint. Through the stages of mechanical engineering technician and industrial experience in sustainability and energy management, he earned his Master of Engineering.
The result: a consultant who understands the technology in the boiler room just as well as the financial calculations in the office. Sustainari was founded to close exactly this gap — between generic consulting and genuine technical optimisation.
