Michael Alexander

Michael Alexander is the co-founder and CEO of Addis Energy, a Somerville, Massachusetts startup turning the Earth's crust into a chemical reactor to make clean ammonia. A chemical engineer who spent more than eight years refining oil at Shell and Marathon Petroleum, he discovered geologic hydrogen at Harvard Business School and teamed up with classmate Charlie Mitchell and MIT professors Iwnetim Abate and Yet-Ming Chiang to commercialize a process that stimulates ammonia production from iron-rich rock underground. In December 2025 Addis raised an oversubscribed $8.3M seed round, bringing total funding to $17.3M.

Reframe Systems

Reframe Systems is a Massachusetts robotics and AI company building net-zero, climate-resilient homes through a network of small, regional 'microfactories.' Founded in 2022 by three former Amazon Robotics leaders, it pairs proprietary 'pixels to parts' design software with vision-guided robotic workcells to mass-customize modular housing - cutting construction costs by roughly 35% and deploying homes in about 100 days. The company aims to make high-performance housing economically viable and to build one million resilient homes globally by 2045.

Mateo Jaramillo

Mateo Jaramillo is the co-founder and CEO of Form Energy, a Somerville, Massachusetts company building 100-hour iron-air batteries that store electricity by rusting and un-rusting iron. After more than seven years at Tesla, where he started and ran the stationary storage business behind the Powerwall and Powerpack, he co-founded Form in 2017 on a contrarian bet: skip lithium, find a chemistry cheap enough to store power for days instead of hours. The company has raised over $1.3 billion, revived an abandoned West Virginia steel mill as its first factory, and signed a roughly $1 billion deal with Google for the world's largest battery system.
