Our Founder

Our founder’s story

Milkywire’s founder, Nina Siemiatkowski, has always had an independent spirit and a passion for nature. After a successful career in finance and as head of marketing at a leading Swedish company, Nina felt unfulfilled. She made a bold change, returning to her original love of photography and traveling to Kenya to document a pride of lions. This experience, captured in her book The Book of Leon, opened her eyes to the urgent need for environmental protection as she witnessed the rapid decline in wildlife populations.

Working with local nonprofits in Kenya, Nina saw firsthand the challenges these organizations faced—committed teams working against immense odds with limited resources. Driven by a vision to reshape how we support environmental causes, Nina founded Milkywire to bridge the gap between companies and grassroots organizations. Today, Milkywire empowers local changemakers to create real impact, connecting companies with those on the front lines of conservation.

A word from our founder

"I founded Milkywire to empower grassroots organizations that protect our planet, but our journey has evolved beyond what I first imagined. As the climate crisis deepens, so has our mission. Today, Milkywire is dedicated to finding and supporting not only local changemakers but also innovative, large-scale projects that hold the potential to solve global environmental challenges. My vision is to bridge the gap between companies and transformative climate solutions, making it possible for every investment to drive measurable, lasting impact. Together, we can redefine what meaningful climate action looks like and create a future where impactful change is within everyone’s reach.”
