Who We Are

Our company was established in 2012, as an extension of Semsa Elektronik – 30-year-old electronics manufacturer in Turkey. The company structure and partnership has changed from Semsa to Semiz, where the goal was to create a corporate structure rather than the family business with extended strategies of high technology, business consultancy and trade on niche areas. We mainly work with white goods manufacturers and their suppliers along with value added electronic card manufacturer in various business segments.


We are investing into Research and Development with a dedicated team to create new ventures with highest technologies in order to meet our customers’ needs in agile and smart manufacturing – globally named as Industry 4.0. Together with in-house developed software and hardware, highest quality is the most crucial KPI at Semiz. Today, we also provide consultancy and software development around Industry 4.0 strategies.


We are traditionally based in Kartal, Istanbul-Turkey at our 30-year-old manufacturing site. Also in 2016, we have expanded our manufacturing, trade and engineering muscles into our new location at Tuzla, Istanbul-Turkey. Today, we are manufacturing at both sites based on 1,000 sqm.

As an open minded and innovative individual, he has led the R&D centre of Erdemir AŞ –the leading steel manufacturer In Turkey- for many years. He has established his first own company in Istanbul, Turkey at 1980 for industrial electronics diagnosis applications. Later he has established Semsa and led the company for about 30 years, and established Semiz Ltd in order to meet customer need of agility and quality with better terms.


Later in 2013, Bilgin Semiz has joined the company, and he owned the total business management of company with support of his father.
