Greentown Labs

We are excited to welcome Massachusetts Executive Office of Economic Development (EOED) Secretary Eric Paley and GE Vernova Chief Technology Officer Krishna Jonnalagadda to the Boston #ClimatetechSummit stage this year for a keynote dialogue with Georgina Campbell Flatter focused on how Massachusetts' and GE Vernova's shared legacy of invention and innovation—from the lightbulb and the telephone to the jet engine and the first subway system—are driving today's modern revolution in clean energy and economic transformation. This conversation will bridge the past and future: as Massachusetts commemorates the 250th anniversary of the American Revolution, these leaders are drawing inspiration from the past to invent the future. Join us for a forward-looking conversation on how legacy and leadership will power the U.S.’s next great era of innovation.

Our team and startups had a fantastic time at #ClimateWeekNYC! Check out photos and takeaways from our CEO Georgina Campbell Flatter 👇 #NYCW

Two big climate weeks in Houston and NYC, 14 of our newest startup members, new ecosystem partnerships with Energytech Nexus and Nominal, a roundup of the latest #startupnews, and an upcoming events roundup (including new #ClimatetechSummit details!)—check it out in today's newsletter:

📍New York, you've been nothing short of amazing this week—the convergence of climate and energy enthusiasts at this year's #ClimateWeekNYC is unlike anything else on the planet. ✨The energy's in full force in every room we've stepped into—including at our Startup Showcase with 12 of our member companies, our marcomms deep-dive with FischTank PR, a Climate Salon focused on cities as climate-innovation playgrounds, the Net Zero Insights report launch, and the many events where we've been cheering on our members, alumni, partners, and friends old and new! Huge thanks to everyone who came to the SOSV Biome to meet 12 of our startups—Active Surfaces, Advanced Ionics, Cala Systems, Carbon To Stone, Cellsense, FAST Metals, Heliotrope Photonics, HKG Energy, Loop CO2, inc., Oxylus Energy, Spare-it, and THOLA—and get to know their technologies, from ultra-intelligent heat pump water heaters to performance-boosting solar panel coatings to bio-based beads for the fashion industry. It was also wonderful for our Chief Growth Officer Aisling Carlson to join our alum Electra's Kellyn Blossom, Arcadia's Adam Offitzer, and FischTank PR's Eric Fischgrund for a conversation about how startups and others can best position themselves to investors and customers in today's landscape. Aisling also spoke at the launch of Net Zero Insights' U.S. Clean Energy & Industrial Innovation report, which we were proud to contribute to (view it here: https://lnkd.in/gjRqB-9s). Huge thanks to Emet Zeitz and team for including us and our member community! Finally, our CEO Georgina Campbell Flatter facilitated the vibrant "Scale Across City Borders" conversation group at Climate Salon alongside Becky Gallagher and Gustavo B.—huge thanks to Victoria Pisini and team for convening these important dialogues! Next up: the Entrepreneurs for Impact (Climate CEOs) meetup, HAX and Newlab showcases, Martin Trust Center for MIT Entrepreneurship showcase and meetup, and more. #NYCW #ClimateWeekNYC #ClimateWeekNY #NYCClimateWeek #NYClimateWeek #innovation #startups #climatetech #energytech #entrepreneurship

It was a treat to celebrate the ribbon-cutting of Loop CO2, inc.'s new 3,000-sq. ft. R&D laboratory in Marlborough, MA—marking another step forward for the startup's CO2-based polymers, the carbon circularity innovation ecosystem, and new #GoodJobs in Massachusetts! ♻️ Loop CO2 uses proprietary CO₂-derived monomers and scalable processes to develop functional, debondable, and upcyclable materials that enable low-VOC acrylics, BPA-free epoxies, biodegradable polyesters, bioplastic chain extender, and chemically recyclable polyurethanes. Think: drop-in solutions for adhesives, coatings, sealant, inks, elastomer in packaging, electronics, and EV automobile batteries—that perform at high standards while reducing environmental impact. The startup's new headquarters in the CITY OF MARLBOROUGH—complete with a 16-foot-tall distillation tower and a 20-liter high-pressure autoclave—will enable further development of its upcyclable CO2-based polymers. Fun fact: the team is now neighbors with our alum and #ACCEL graduate SpadXTech, which recently opened its new HQ for its microbe-grown plastic alternatives in the same Cedar Hill Street building! 👯 Huge congratulations to AONE W., Jimmy Chiu, Ph.D., Ian Tonks, and the entire team!
