Climate Scale-Up: Born from the MIT Ecosystem, Addressing the Missing Middle in Climate Tech


Climate Scale-Up is a prestigious, year-long program helping venture-backed, growth-stage climate tech companies scale globally. We connect founders with investors, partners, and decision-makers through strategic mentorship, curated introductions, and high-trust convenings. Anchored by a week of exclusive events in Davos during the World Economic Forum, Climate Scale-Up accelerates the path from commercial traction to international deployment—closing the funding and partnership gap known as the “missing middle.”

Who Is Climate Scale-Up For?

Climate Scale-Up is designed for key change-makers driving the climate transition: innovative scale-ups, catalytic investors, and strategic partners. It serves growth-stage climate tech companies with scalable, high-impact solutions ready for global expansion. It connects these innovators with a global network of investors—venture capital firms, family offices, and institutional funds—who are actively seeking curated, trusted opportunities. The program also engages enablers such as governments, corporates, and service providers who play a critical role in building innovation ecosystems, deploying technologies, and unlocking new markets. Together, these stakeholders form the collaborative ethos needed to accelerate climate solutions from breakthrough to scale.
