About DEV Joni

DEV Joni is a full-stack technology business operated from Hyrynsalmi, Finland. Since January 2023, we develop software and hardware products that are

We are a full-stack technology business meaning we control the entire production process from design to assembly. We also develop the software powering our own devices. This expertise spanning hardware and software allows us to build cohesive and well-function products. Nearly all our hardware and software products are open-source and we ourselves use open-source tools. Openness brings several advantages such as complete customisability by users and prolonged product life-time. Our business model is sole proprietorship (aka. private trader), in which the entrepreneur Joni directly controls all business decisions. The lack of shareholders or voting procedures makes us trustworthy partners who can react quickly and prioritise our values over quarterly earnings. This autonomy synergises particularly well with the open-source business model.

About our products

The products we sell are our original open-source designs that target scientific and industrial users: Mounting frames, light sources, computer controllable sensors and motors etc.

We acquire the so called elementary materials (e.g. micro-controllers, resistors, plastics) from EU redistributors and vendors, and stock them in our storage spaces for quick 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, some 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 are also able to customise our existing products according to your needs.
