Sam Teicher co-founded Coral Vita, a social enterprise that grows resilient corals up to 50 times faster to restore dying reefs. Coral reefs sustain roughly 1 billion people’s livelihoods and 25 percent of marine life while powering tourism economies and sheltering coastlines from storms. But half are dead and more than 90 percent are on track to die by 2050. Coral Vita grows corals in months instead of decades while strengthening their resilience to climate change threats. By selling restoration as a service to reef-dependent customers, it works to unlock critically needed funding to preserve these magnificent ecosystems for future generations. Teicher previously worked on climate resiliency initiatives at the White House and for the Global Island Partnership, is a Forbes 30 Under 30 Social Entrepreneur, was a contributing author to SDG 14, launched Coral Vita during his master’s program at Yale University, and has loved the ocean since becoming a scuba diver as a kid.
