Manuel Liedot – CEO

Having graduated with a structural engineering degree from ESTP in Paris, I joined Graitec in 1993 to pursue my passion for not only the industry, but how I could bring technology into the workplace and help companies work more effectively.

I was co-inventor of the French leading Rebar design and detailing software Arche (together with the founder of Graitec, Francis Guillemard and the now V.P of AEC at Autodesk, Nicolas Mangon).

Having worked in software engineering, customer support, product management, and business development I now lead Graitec globally. I am extremely proud to serve as CEO, as Graitec has a high industry vision for the future, extremely loyal clients, and over 700 highly skilled staff.
