about plum

We provide electronics for smart energy management in IoT systems. Our solutions are dedicated to the HVAC, GAS and WATER industries. 
We create OEM solutions while we treat each product and its implementation individually. We guarantee full implementation and post-sales support from our R&D department. 
We are Agile. We develop all our projects using SCRUM methodology, which allows us to implement our devices faster and more effectively. 
We manufacture our products in Poland. By producing locally, we can ensure quality control and reliable delivery of our product. We design competitive and interoperable devices that can work with devices from other suppliers. 

We prioritize cooperation, business partnerships, and the development of products, both in terms of hardware and software. This is our promise and our competitive advantage.
