Welcome to our inaugural class of startups: Cohort 417. Comprising nearly 50 promising companies from around the globe, they're the largest climate tech innovation cohort the world has ever seen. No other similar program or venture boasts so many startups in their cohorts, but the magnitude of the climate crisis challenge demands a bigger, bolder approach.
Why 'Cohort 417'? Our inaugural cohort is named for this year’s peak atmospheric carbon dioxide concentration of 417.1 parts per million (ppm), based on the Keeling Curve, recorded in May 2020—which is when we put out our first call for applicants. It's a uniquely fitting reminder of the common mission that brings us all together: rising to meet the size and urgency of the climate crisis.
