Adam Ornstein is the founder and CEO of Fiora Mara, a climate tech company focused on permanent, low-cost carbon removal in the open ocean. His work centers on designing scalable systems that turn the ocean’s vast vertical water column into a reliable carbon sink, using fast-growing marine biomass. Adam leads the company’s carbon strategy, field experiments, technology, and partnerships across New York’s climate innovation network, advancing approaches aimed at gigaton-scale impact by 2033. Before Fiora Mara, he spent more than a decade scaling products and teams in health and data technology, including driving Everyday Health Professional's growth from 380,000 to over three million users and also leading innovation at companies like Thomson Reuters and WebMD. He’s a past ClimateBase Fellow, a Climate Reality Leader, and a builder committed to solving carbon at planetary scale.
