Why it matters

Europe’s fastest PCB prototypes

Building hardware at the speed of software!

Europe has lost the ability to make electronics quickly and locally. Hardware teams wait days to weeks for every prototype – or send their design data to Asia. Each day of waiting delays testing and costs Europe ground in a race where speed decides.

That's why we built a software-driven factory in Prague that manufactures prototype PCBs the day after you order, from a single piece.

The development of a new prototype can be delayed by weeks because of waiting.When we want to order cheap PCBs, we have to send them to China, along with our data.Every day we wait for the prototype to arrive the whole development is set back.

Our solution

We have developed new technology and optimised our processes so that we can manufacture any PCB the next day. But we don’t stop there; we are developing our own software for PCB inspection and design. Our software can identify errors, flag them and correct them.

We want to bring development back to Europe, and with it the passion for pushing the boundaries of what is possible.

With the rise of AI technologies, we are seeing that even hardware design is shifting increasingly towards the use of AI, which helps engineers translate their ideas from their minds onto a computer.

The problem, therefore, is no longer coming up with ideas – people have plenty of those. Nor is it designing the circuit board. AI tools take care of the design in minutes. So where does the new challenge lie for rapid prototyping and bringing new products to market?

The challenge is getting a quickly manufactured board to the developer so that they can test it, correct it, have it remanufactured, and repeat the process over and over again. Waiting for a prototype to be delivered is therefore another point where the entire development process is held up.

History

From Frustration to Next-Day PCBs

CircuitNinja was born while we were studying at the Czech Technical University in Prague, driven by our frustration with slow prototyping. Today, we develop the machines, software, and manufacturing processes that enable engineers to get their boards quickly, locally, and without unnecessary red tape.

Rocket Engineering Brought Us Together

We met through rocket engineering projects at CTU. It was there that we repeatedly experienced how waiting for the next PCB revision delayed testing and slowed down the entire development cycle.

We Founded CircuitNinja

We were tired of waiting, so we started manufacturing the boards ourselves. When we realised that other engineers faced the same problem, we combined our expertise in electronics, mechanical engineering, and software to build a technology company.

September 2025

We Were Named Startup of the Year

At the 2025 Idea of the Year competition, a Czech competition supporting new ideas, we received the Startup of the Year award as the project with the greatest growth potential. The recognition reinforced our belief that CircuitNinja addresses a genuine need and that demand for fast PCB manufacturing is strong.

We Manufactured Our First PCBs for Customers

We moved from in house prototypes to real customer orders. Delivering our first boards proved our technology in day to day production and opened the next chapter for CircuitNinja: manufacturing for customers.

Today

Open to Everyone

We have integrated our manufacturing machines, control software, and every production step into a single digitally managed process. This enables us to manufacture anything from one off prototypes to small production runs with next-day manufacturing. Online ordering is open to everyone, and we keep improving our processes and manufacturing technology together with our customers.

Building Hardware at Software Speed
Our Next Milestone

Building Hardware at Software Speed

We are not just another PCB manufacturer. We are building a digitally controlled factory that reduces the journey from design to finished board from weeks to hours. Our ambition is to make it possible to rapidly prototype and manufacture critical electronics in the heart of Europe.
