Danish greentech company Watts opens software competence center in Vilnius

Watts, a Danish greentech company specialising in smart home energy solutions, has established a new software competence center in Vilnius. Over the next three years, the company plans to hire up to 100 engineers and technology specialists to accelerate development of its smart home energy platform.  

Founded in 2016 in Køge, Denmark, Watts develops integrated renewable-energy solutions that help households track their energy consumption and make informed, data-drive decisions to reduce their environmental impact as well as manage costs more efficiently.  

Today, more than 700,000 Danish households use Watts’ energy app (WattsOn), smart devices, and its intelligent Homegrid™ system to monitor consumption, understand usage patterns, and optimize their daily energy choices.  

The Vilnius competence center will be responsible for core software development across the entire Watts ecosystem, including back-end services, mobile applications, embedded software, EV charging intelligence, and advanced predictive algorithms. 

According to Per Madsen, Director at Watts, choosing Lithuania was not only a strategic decision – it was a human one: "Our first collaboration with Lithuanian engineers exceeded all expectations. The talent here is world-class, but what impressed us most was the mindset – people genuinely want to build meaningful products. Watts was founded to reduce CO₂ emissions and create real impact in people’s lives, and in Lithuania we found a talent pool motivated by that same purpose. That’s why we’re here. We’re building our future products together."

As part of its long-term vision, Watts plans to bring its consumer app – WattsOn – to Lithuanian households. The company has begun preparations to integrate with the ESO Data Hub, enabling Lithuanian users to access detailed consumption data, track their CO₂ footprint, and benefit from the same intelligent alerts and insights trusted by users in Denmark.
