Activate Welcomes 47 New Fellows to Cohort 2025

The new 2025 Cohort is powering America’s next hard tech leap
Today, we are announcing the next cohort of 47 scientists and engineers who are joining the Activate Fellowship. The 39 companies of Cohort 2025 are developing technologies across 14 industries and represent 29 cities and nine states in the U.S., spanning Activate’s four hub communities – Berkeley, Boston, Houston, and New York – as well as Activate Anywhere, the remote-based community that includes fellows across the U.S.
“Science entrepreneurship is the origin story of tomorrow’s industries,” said Cyrus Wadia, CEO of Activate. “The U.S. has long been a world center for science leadership and technological advancement. When it comes to solving the world’s biggest challenges, hard-tech innovation is how we unlock the best solutions. From infrastructure to energy to agriculture, these Activate Fellows are the bold thinkers who are building the next generation of science-focused companies to lead us into the future.”
