Greentown Labs

Episode 17 of the Fall Coworking Chronicles has us traveling to Greentown Labs, Part 1… We caught up with Georgina Campbell Flatter, CEO at Greentown Labs and Casey Johnson and Cassie (Cassandra) Lowell from studio 3e8 on this segment… Greentown Labs is the largest climate and energy incubator in the world. They are a home for entrepreneurs in Boston (and Houston) providing physical infrastructure to help them grow, scale, and move fast. Everything they do is about the entrepreneur, removing friction, and setting them up for success. Georgina Campbell Flatter, CEO at Greentown Labsshares… Building a community around entrepreneurs is critical. Greentown engages industry partners, investors, mentors, and alumni. Greentown Labs is hosting a Climatetech Summit on November 6th in Boston. Learn about what is next and how to contribute. Make sure all members of the community check it out! Casey Johnson, Co-Founder & CEO and Cassie (Cassandra) Lowell, Co-Founder & Chief Product Officer from studio 3e8 share… studio 3e8 make things that make things. They’re building metal 3D printing on a desktop form factor. Any of the companies at Greentown could run it on their desk, plug it into a standard wall outlet, and run it safely in the room without air handling. The team has doubled their team, tripled their lab space, and have a whole fleet of parts running now since they arrived at Greentown Labs <1 year ago. It’s been an awesome experience! Climate controlled space at Greentown Labs, weekly roundtables, a machine shop and learning from their neighbors (plus mentors) has been a huge part of their Greentown experience. Boston is a community that loves its hardware (and 3D printing)! The fall tour continues with MGMT Boston. Thanks to Rho and Will Panarello for supporting this series!

📣 Extreme-weather-resistant buildings? Ultra-fast construction? Builders are seeking smarter, more efficient, and more resilient approaches. And Amrize is partnering with the world of start-ups to make them happen. Today, Amrize teamed up with Greentown Labs, the largest incubator in its sector, at its highest partnership level—joining the likes of GE Vernova and Amazon. As Aisling Carlson, Greentown’s Chief Growth Officer, says, Greentown Labs startups are “revolutionizing how buildings are planned, built, and managed,” and “Amrize will play a key role in rapidly bringing these technologies to market.” Our partnership with Greentown Labs is part of Amrize’s wider engagement in the innovation ecosystem that includes several collaborations, such as: 💡MIT (Massachusetts Institute of Technology), helping bring novel technologies to challenges like value chain resiliency 🔋Sublime Systems, a Greentown startup making cement using 30-40% less energy ⚡Travertine, applying electricity to make carbon-negative calcium carbonate We’re excited to be joining some of the brightest minds in innovation, to #BuildYourAmbition.

🌱 Bigger thinking, bigger ambition, together — reflections from Climate Week NYC What I walked away with is simple: we can’t solve small. Hard problems demand bigger thinking, bigger ambition — and with so much already happening, accelerating together is how we get there. Coming off Houston Energy & Climate Startup Week and into New York, it underscored the power of these moments: not just noise, but real relationships being built, investments made, partnerships shaped, and knowledge shared. The quality of voices across panels, keynotes, and networking was striking — diverse perspectives, serious ambition, and entrepreneurs driving real progress. Together, it all moves us closer to what this decisive decade demands: more energy, less emissions, and good jobs. Here’s what stood out — and where entrepreneurs fit in: Surging demand changes everything. Electricity needs could rise 2–4x this decade, driven by data centers, AI, and electrification — making (and scaling) grid innovation and new generation non-negotiable. The challenge is clear: deliver more energy, with fewer emissions, fast. #10years Meeting surging demand takes more than new wires. Transmission build-out is too slow and costly on its own. Smarter planning, better use of idle capacity, and a more diversified mix of energy — from demand response and distributed generation to new baseload like geothermal — are essential. Rising costs and supply chain pressures make this both urgent and a HUGE opening for innovation. Cities are proving grounds. First-of-a-kind projects can happen when startups, governments, corporates, and communities share risk — and the potential for scale from there is enormous. Unit economics + utilization matter!! Founders who can prove cost, reliability, and performance will drive adoption fastest. Scaling across borders isn’t copy-paste. Founders need consistent support, with local flavor—customers, pilots, policy windows. Platforms matter. Giving entrepreneurs space to share progress and showcase the diversity of solutions is one of the most hopeful parts of weeks like this — and the connections they build are critical for the speed at which solutions can scale. Speed matters. (so proud to see Greentown Labs very first dedicated event!) Friendships matter too. These gatherings are also about enjoying the journey — catching up with friends across Massachusetts Institute of Technology Acumen TomorrowNow.org #Houston #Boston #UK ++(with some epic after-parties …!) — and building the trust that keeps this movement strong. A huge shout-out to the Greentown Labs team, our startups, and our partners — your voices were EVERYWHERE this week, showing what urgent optimism looks like in action. Our bet is clear: entrepreneurs are building the solutions that will change the world. If you’re ready to pilot, find customers, and scale—we’re here in Boston and Houston to help you get there faster. #MoreEnergyLessEmissions #ClimateTech #FoundersFirst #UrgentOptimism
