What you will learn:


Johanna Wolfson is a Co-founder and General Partner at Azolla Ventures, a venture fund focused on investing in early-stage hardware companies with gigaton-scale emissions reduction potential by 2050. With a PhD in Physical Chemistry from MIT and experience at the Department of Energy, she specializes in eliminating barriers to commercialization for capital-intensive climate technologies. Her innovative approach to "catalytic capital" deployment enables support for high-impact climate solutions that may be too risky or long-term for traditional venture funding. 


As a leader in climate tech investment, Johanna sits on the boards of several companies in carbon removal, agriculture, and mining, where she helps bridge the gap between breakthrough technologies and market implementation. Her work at Azolla Ventures demonstrates how strategic investment can accelerate the development of crucial climate solutions while maintaining both environmental impact and financial viability.
