Finishing off the year with a bang! Thanks so much to everyone who joined us at our final #EnergyBar of 2024, celebrating an amazing year full of #ClimateAction in our members' growth and accomplishments. We were proud to share that 90 of our startups and alumni secured funding in 2024, collectively raising more than $1.8B—and many hit major deployment milestones, including Sublime Systems, Sol Clarity, Stepwise, Reframe Systems, AeroShield Materials, Dandelion Energy, and many more. This is just a small sampling of the accomplishments our members have achieved this year; stay tuned for an end-of-year roundup of our members' biggest milestones of the year! Thank you to Siemens for sponsoring this event and to Jim Gernatt, Jr. of Siemens Digital Industries for taking the stage to share more about how the company supports startups, including through the Siemens Xcelerator for Startups software program.

In the four years since Sublime Systems was spun out of MIT by Leah Ellis and Yet-Ming Chiang, it’s seen immense growth by every metric—going from its first gram of decarbonized cement to a 250-ton-pear-year pilot plant, from two founders to a team of more than 85, and from $0 raised to over $200M. In that time, its team worked tirelessly in our wet and prototyping labs to rapidly progress from bench-scale iteration to product testing to pilot-system production. Now, the startup is building a manufacturing plant in Holyoke, MA that will be capable of producing 30,000 metric tons of cement per year. Along the way, the company's hit dozens of R&D, capital, deployment, and partnership milestones, including big-ticket grants from ARPA-E and the U.S. Department of Energy (DOE), investments and partnerships with our partners SCG, Microsoft, Vineyard Offshore, and Holcim, and much more.

If you're seeing this post, you probably already know how grand the climate challenge is—and how much innovation is needed to address it. But innovation isn't easy: it requires grit, guidance, enthusiasm, and mentorship, and that's not to mention basic capital, software, and physical tools. That's where we come in: cultivating a community of fellow founders; providing expert advisors, physical tools, and lab space; and connecting founders to the investors and corporate partners who will ultimately help propel their tech out of the lab and into the world. This #GivingTuesday, we need your partnership to support startups in getting their crucial technologies out into the world. At a time when Greentown, our startups, and the broader climatetech industry are facing headwinds stemming from market trends, the recent U.S. election, and an investment chill, your support is more important now than ever. Your generous help this Giving Tuesday will empower Greentown and our startups to continue scaling climate solutions in 2025 and beyond. Learn more and donate here: https://lnkd.in/encGAgGw
