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.

Featured Cases

  • 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.

  • Arusha, Listen!

    Deaf children in Tanzania face severe marginalization, often denied education and a future. Through documentaries and video series, we made Arusha, Kuule! visible, amplifying their struggles and the life-changing work of Finnish Special Education Teachers in Africa. Our expertise helped bring their message to the Western world, making their work viable and impactful. Recognized as the most impactful NGO of 2024, Ego raised €500K—empowered by our storytelling.

  • Foilone

    Foilone is redefining emission-free boating. And we’re the ones amplifying their vision.

    As their marketing and content partner, we craft the narrative behind their groundbreaking technology, building a globally competitive brand. From brand films to a full-scale marketing toolkit, we help position Foilone’s innovation to transform the future of boating.

  • Ronald McDonald House Charities

    The stories we share from the House are about children facing some of life’s most difficult challenges—such as serious heart conditions requiring intensive care. Through Ronald McDonald House Charities, a facility in Helsinki provides a comforting home and vital resources for families during these incredibly tough times. Contributing to this cause by sharing these stories is how we truly feel we're making a meaningful difference.

  • Transmeri Group

    Transmeri Group wanted to highlight the achievements of its 2020–2025 sustainability program as well as its future goals. We produced a package that included one long video and several short videos, each focusing on a specific theme of the sustainability program.

    The videos showcase the company’s sustainability journey, the concrete results achieved so far, and the direction of future development. The content was designed to work in both internal and external communications, strengthening Transmeri’s position as a responsible company.

Our Services

Ensuring Sustainability Actions Reach Their Commercial Potential.

We create video-based campaigns and content that make sustainable business actions clear, easy to understand and engaging. Video helps explain complex topics, build brand trust and connect with different audiences.

Our storytelling approach combines strategic thinking, a documentary style and clear visuals. We show what companies are really doing for sustainability, in a way that is honest, easy to follow and thoughtfully crafted. Goal is to help people understand, build trust and show why these actions matter.

We work with themes like:

Environmental and climate action
Reducing emissions, protecting nature and using materials more wisely. We tell clear and concrete stories that show how these actions make a real difference.

Social responsibility
Fair treatment, equal opportunities and responsible supply chains — shown through real people and real actions, in an honest and open way.

Education and internal communication
Helping staff stay motivated, committed and informed about sustainability, as part of everyday work and company culture.

Brand building
Using sustainability as part of your brand story. Communication that helps you stand out, builds trust and creates long-term value.

We transform reports into clear and impactful video content that brings the most important messages to life. By identifying the most essential themes, we build strategic narratives that enhance understanding and create emotional connection. Through creative storytelling and visually compelling execution, reporting becomes a powerful commercial tool, not just a compliance task.

Potential themes:

Strategic sustainability topics
Drawn from reports and presented as accessible, engaging narratives to support stakeholder understanding.

Climate goals and actions
Turned into clear stories that connect long-term objectives with concrete steps.

Climate transition plans
Visualized as credible, understandable roadmaps toward a more sustainable future.

Company-relevant requirements explained in a digestible way: what standards apply, what the impacts are, and how they are managed.

Double materiality assessments
Results on impacts, risks and opportunities turned into relatable content that stakeholders can internalize.

Stakeholder voices
Employees, communities and other key voices included as part of the story, adding depth, authenticity and emotion to sustainability work.
