Electronic and Digital Turnkey Solutions by Code99
You dream it. We build it. All from a single source.
Custom Embedded Systems that make anything possible.
Conveniently nestled in the heart of Freyung, Lower Bavaria (south-east-germany), Code99 crafts specialized electronics and embedded systems solutions with great attention to detail and the highest standards of quality. Located within the GreG FRG digital startup center, Code99 benefits from excellent infrastructure, expert coaching (including from BayStartUP), and a strong network spanning regional universities and cross-border partnerships with the Czech Republic.
We specialize in a wide range of technical fields, which makes it easy for us to offer complete solutions from a single source. Our strengths lie especially in electronics, IT, device engineering, and software development—areas where we truly feel at home.
Code99 was founded by Christian Wilhelm, born in 1978.
From a young age, Christian showed a deep fascination with technology—taking apart every device he could get his hands on, even fully working radios weren’t safe. His journey into computing began in 1989 with a Commodore 64. In 2004, he took the leap into self-employment under the name “Wilhelm Computer.” The brand Code99 was eventually born in 2018.

Why choosing Code99 is a decision you can feel good about
- Everything we do is Open Source: All our projects are publicly available on GitHub or can be downloaded for a minimal handling fee (usually €1). Paradoxically, this very approach makes our software more secure than proprietary systems ever could be.
- Quality only happens without time pressure: We intentionally avoid hard deadlines and follow the principle: a system is ready when it's truly ready — not just because a date says so. No one benefits when something is rushed to completion at midnight with sweaty hands, only to crash later due to overlooked bugs or sloppy spaghetti code.
- Full Transparency: From order acceptance all the way through delivery, you gain insight into our entire production process. We have no secrets and value an open, respectful partnership where trust can grow naturally.
- Focus on User-Friendliness: We develop software and user interfaces based on principles common in the Linux world. This includes avoiding (annoying) message boxes, implementing well-thought-out human-machine interfaces, and simply letting the user get their work done without interruptions.
- Service before sales: The customer and the product always come first. Even hobbyists who build their own solutions based on our open-source code receive our full support. We don’t know the words “can’t be done,” “we don’t do that,” or “that doesn’t exist.” The service desert is already vast enough — we don’t want to be part of it.
