Our journey has taken us from developing one of Sweden’s largest virtual power plants by connecting over 15,000 buildings, to using AI to optimize energy, water, and resource management around the world. We have also helped launch award-winning cleantech startups and SaaS solutions for the energy sector.

But we don’t just measure success by the impact we have on our customers. We measure it by the real-world sustainability gains our solutions create. When our customers tell us that our solutions helped shut down a coal and oil power plant, integrate more renewables into their portfolio, or cut 36,000 tons of CO₂ emissions annually, we take immense pride in that.

At Helicon, speed, curiosity, collaboration, and continuous learning are at the heart of everything we do.
