Company: Langbrók (Consulting Agency)
Designation: Founder
Country: Iceland
Soffía Sigurgeirsdóttir is the founder of Langbrók, a consulting agency based in Iceland, where she works at the forefront of sustainability, strategy, and societal transformation. Her work is grounded in a strong academic foundation, holding a Master of Science (M.Sc.) in Theory and International Relations from the London School of Economics and Political Science and a Bachelor of Arts (B.A.) degree in Psychology from the University of Iceland. She has further pursued studies in Psychology at University College Dublin and Philosophy at the University of Iceland, reflecting an interdisciplinary approach that continues to shape her perspective on leadership, human behaviour, and systems-level change.
Throughout her career, Soffía has worked closely with companies and organizations to enhance their positive societal and environmental impact while actively reducing negative effects across operations and value chains. As a sustainability consultant and strategist, she focuses on helping organizations move beyond compliance-driven frameworks toward genuine transformation and long-term value creation. Her work extends into global leadership dialogue through her involvement with the Reykjavík Global Forum and the Wellbeing Economy Forum in Iceland, where she has supported initiatives that challenge conventional definitions of economic success by placing sustainability, gender equality, and human wellbeing at the centre of progress. A strong advocate for women’s leadership, she works actively to increase visibility, influence, and opportunities for women across sustainability, business, and exploration.
Beyond her advisory work, Soffía brings together leadership, philanthropy, and adventure as interconnected platforms for empowerment and social impact. She is the founder of Climb for Change, an initiative dedicated to supporting Nepalese and Sherpa women mountaineers by expanding access to participation in the high-altitude mountaineering sector, an industry historically dominated by men. As a mountaineer herself, she has climbed peaks in Nepal to raise awareness and funding for the initiative while promoting gender equality and economic empowerment within mountain communities. In Iceland, her involvement with Lífskraftur (Lifeforce), a charity focused on supporting cancer-related projects and promoting outdoor activity as a pathway to wellbeing, reflects the same values. Through this work, she has participated in women-led expeditions, including crossing Iceland’s largest glacier on foot, using these journeys to raise awareness, generate funding, and symbolise resilience, recovery, and the restorative power of nature.
Looking ahead, Soffía’s vision centres on building sustainable wellbeing societies where leadership is defined not only by financial outcomes but by long-term responsibility, inclusion, and meaningful impact. She believes the next generation of leadership must be interdisciplinary, collaborative, and purpose-driven, with stronger representation of women shaping global decision-making. By combining sustainability strategy, philanthropy, and exploration, Soffía Sigurgeirsdóttir continues to inspire organisations, communities, and future leaders to pursue bold solutions that strengthen both human wellbeing and planetary health for generations to come.
