About Us

Who are we at Zekeng?

Zekeng is a world class company that offers stellar prototyping services, from A-Z, at competitive prices. We’re not only passionate engineers building innovative products and generating impact, though. As entrepreneurs ourselves, we implicitly understand what it takes to bring an idea to fruition. We act as a strategic partner, here to help guide you to the next level.

Our Story

Established in 2007 in Sofia, Bulgaria, Zekeng initially operated as a custom PCB layout design studio. Over the years we gradually expanded our team and added more services to our portfolio like PCB assembly, rapid prototyping, firmware development, industrial design and feasibility studies. Our clients come mainly from Europe and North America.

People Behind

Zekeng team is built of electronic engineers, industrial designers and firmware developers, most of them with 15+ years of experience in their respective field. Some of the companies they worked for before joining us are: Google, Kostal, Nokia, Dellorto, Datecs.


In an age of exponential growth in technology, hardware products are becoming extremely popular. We provide solid expertise and sophisticated engineering practices for turning your ideas into ready-for-market products. Our mission is two-fold: make hardware development accessible and provide a full suite of prototyping and startup services. You can confidently rely on Zekeng to take care of it all.

We offer accessible hardware development
through convinient plans.

You have a hardware product idea, but you don’t know where to begin. The direction you should go in, costs, technical expertise, management and scope of your project can be overwhelming. Here is where Zekeng can help you by discussing your idea and its feasibility via consultation.


As an early stage startup, you’d like to further develop a product while reducing costs. A leasing agreement will allow you to pay just a fraction of your project’s expenses during its development. The rest is due only when you start making money!


We’ve honed our technical expertise over the past 9+ years as outsourcing specialists. If you have expert domain knowledge in your field, we can integrate as a side team and help you execute your project.
