We turn every spark of an idea into a real product — from first concept to full production — and bring smart automation to over 3 million households around the world. From heating, lighting, appliances, curtains, and more — if it runs on electricity, chances are we can automate it. We’ve built over 100 smart devices (and counting!), and everything happens right here at our headquarters in Sofia.
