MassMutual Ventures has launched Climate Technology Fund II (CTF II), a $150 million venture capital fund aimed at early-stage companies using climate technology and AI to improve real assets like energy infrastructure, real estate, and natural resources.
The fund will back North American companies building physical and digital technologies that help asset owners and operators boost performance, cut costs, and manage risk. It sits at the crossroads of three converging trends: rising demand for clean, reliable energy; growing physical and operational risk across real assets; and the spread of AI applications tailored to specific industries.
CTF II builds on MMV’s first Climate Technology Fund, launched in 2023, which has backed 16 companies across clean power, energy systems, digital infrastructure, and climate adaptation. The new fund brings MMV’s total climate technology commitment to $300 million.
“Surging power demand, unprecedented infrastructure investment, and rising physical climate risk are creating massive opportunities for entrepreneurs applying technology to real assets,” said Timothy Krysiek, Managing Partner of MassMutual Ventures Climate Technology Fund. “Startups improving how energy-related infrastructure is developed, financed, operated, and protected will benefit from powerful macro tailwinds. But the path to commercialization requires deep sector expertise, connections to asset owners and operators, and customized capital solutions. We designed CTF to support founders applying climate technology and AI to improve the efficiency, resilience, value, and sustainability of real assets.”
MMV sees the strongest opportunities in companies that can turn technology into measurable economic value for asset owners and operators, and CTF II is built around that thesis.
“Climate investing is evolving from broad thematic exposure toward specialized strategies that understand where technology creates tangible value in large, complex industries,” said Doug Russell, Head of MassMutual Ventures. “CTF II is designed for that next phase. The fund brings together deep climate and energy sector expertise, a disciplined investment process, and a connection to MassMutual’s unique set of assets and capabilities. We believe that combination provides CTF II with a differentiated platform to support founders building the next generation of leading climate tech companies.”
Herald View: CTF II marks a pivot from thematic climate bets to infrastructure-grade specialization. Doubling MMV’s commitment to $300 million and tying returns to measurable asset performance shows where climate capital is heading next: AI-driven efficiency in real assets, not broad sustainability narratives.
