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- Easy to use
- Open source - Extend, modify and share as you wish
- Relatively affordable
- Recyclable and reusable
We call ourselves a full-stack technology business. This term reflects the fact that we control the entire production process from design to assembly, and from hardware to software. Moreover, we sell directly to our customers and listen their feedback. Our expertise spanning from hardware to software, and the continued interaction with our customers, allows us to build cohesive and well-function products for the harshest of environments.
Nearly all our hardware and software products are open-source and we ourselves also use open-source tools to make them. This open approach brings in several advantages such as total user-customisability and prolonged product life-time. The customisability is especially important in scientific and industrial settings where requirements are specific, and sometimes, odd. By embracing our users to modify their devices to their needs, our users can find wider use of our devices than otherwise possible.
Our business model is sole proprietorship (aka. private trader), in which the entrepreneur Dr Joni Kemppainen directly controls all business decisions. The lack of shareholders or voting procedures makes us easy-to-predict partners who can react quickly and prioritise your and our values over quarterly earnings. We believe that this autonomy synergises particularly well with the open-source business model.
More about our products
The products we sell are almost without an exception all our original open-source designs that target scientific and industrial users: Mounting frames, light sources, computer controllable sensors, motors and so on.
We acquire the so called elementary materials (e.g. micro-controllers, resistors, plastics) mainly from EU redistributors and vendors, and stock them in our storage spaces for reliable and rapid access. Our hardware and software R&D, manufacuring and programming is all done in-house, giving us total control of the entire production process.
We sell our products directly in our web shop Shop DEV Joni. Payments are accepted via PayPal, credit-cards or custom quotations and invoices. In addition to the web shop, you can order via email (solutions@devjoni.com). Due to limited demand, many of the products are manufactured on-demand. If you have ideas of products you would like to see in our catalogue please leave us an email. We can also customise our existing products according to your needs.
