About DEV Joni

DEV Joni is a technology business operated from the town of Hyrynsalmi, Finland. Since January 2023, we are developing software and hardware products that are

We are a full-stack technology business, which means we control every aspect of the production process - from design and development to assembly, hardware and software. By interacting directly with our customers, we stay closely connected to their needs and feedback. This direct interaction, combined with our expertise across most areas of technology, enables us to create cohesive, high-performance products built to thrive in the harshest environments.

Nearly all our hardware and software products are open-source, and we, too, use open-source tools in their creation. This transparent approach offers numerous benefits, including complete user customisability and extended product lifespans. Customisation is especially crucial in scientific and industrial fields, where requirements are often specific - and sometimes unconventional. By empowering our users to modify their devices to meet their unique needs, we unlock a broader range of possibilities and applications for our products.

We operate as a sole proprietorship (also known as a private trader), with Dr. Joni Kemppainen, the entrepreneur, directly overseeing all business decisions. Without shareholders or voting procedures, we are agile and predictable partner, able to respond swiftly and prioritize shared values over short-term profits. We believe that this autonomy is a perfect match for our open-source business model, allowing us to stay true to our principles while delivering value to our customers.
