Innovation is reshaping how we respond to planetary crises, from climate change to chemical pollution to biodiversity loss. Drawing on insights from the natural world, deeptech innovators are developing solutions that strengthen climate resilience and advance planetary wellbeing. These transformative technologies not only address critical challenges but also unlock new opportunities for markets, communities, and a more sustainable future.
At the Planetary Embassy at Climate Week NYC, Swissnex, Droplet VC, and Helvetas USA are bringing together a unique mix of voices to spotlight climatetech and deeptech innovation emerging from Switzerland and Europe. The conversation will feature inputs from CellX Biosolutions, a Swiss startup harnessing the power of bacteria to break down even the most persistent chemical pollutants, and REOR20, a Swiss firm pioneering AI-driven flood hazard intelligence to enhance resilience in a changing climate.
This Investor Summit convenes venture capital, international development, and innovation diplomacy leaders alongside startup founders whose technologies are poised to transform global markets and strengthen the foundations of planetary well-being.
