When first developing BLOCKS, co-founders Serge and Ali had conflicting visions of the ideal wearable device. Unwilling to compromise but determined to collaborate, they found an elegant solution: modularity. An innovative design that could provide the necessary versatility to accommodate an armoury of ideas and innovations, customizable, adjustable and transformable. BLOCKS was born out of the mission to make technology truly personal. To empower individuals through providing the means for them to build and design a device that is theirs.

Technology is an extension of the individual. Compromise leads to mediocrity. Convergence obstructs creativity.

Choose BLOCKS. Your Device. Your Way.


Serge Didenko

Chief Executive Officer

Serge Didenko, Co-founder of BLOCKS Wearables Ltd., completed his MEng in Bioengineering at Imperial College London. His avid interest in entrepreneurship led him to spearhead efforts to kickstart the Imperial Innovation Hub, which has since served as a stepping stone for numerous break-through ventures. Following his passion for biomedical technology, Serge went on to study a PhD in Medical Computer Science. Serge's excitement for the potential of new age wearables led him to the inception of BLOCKS, alongside Co-founder Alireza Tahmaseb.
