We believe in stories that speak, connect and illuminate, transforming social and engineering feats into human-centric storytelling.
At Reaktiv, we believe that authentic and reliable communication around sustainability is the only way for companies to earn trust and build meaningful relationships with stakeholders.

Honest and transparent storytelling has become the new benchmark for communication that connects and builds lasting trust. The landscape is changing. Regulations are tightening and expectations from consumers and investors are growing.

We turn sustainability efforts into tangible business value by combining deep expertise in sustainability, strategy, new-age marketing, and communication. Our approach ensures that responsible actions translate into competitive advantage, real market impact – and most importantly, that the stories and efforts that truly matter are seen, heard, and understood.

Fortum PPA

In collaboration with sakea we explored where real climate impact happens. As a leading Nordic low-carbon power supplier, Fortum powers heavy industries with fossil-free energy, enabling companies like Eesti Energia, Stegra, and Vargön Alloys to meet ambitious climate goals.

Stegra, as a forerunner in green steel, is helping reshape an industry responsible for 7–9% of global CO₂ emissions. Valtteri & Co together with team Fortum scripted, produced, and executed a powerful, commercially driven video series—Showcasing Fortum's role in supporting industrial decarbonisation.
