A large climate technology incubator providing lab and prototyping space to hardware-heavy startups.
Greentown Labs is a climate technology incubator built around a problem most accelerators cannot solve: hardware companies need workshops, lab benches, and heavy equipment long before they need pitch coaching.
Members rent space in a shared facility with prototyping infrastructure, alongside a community of companies facing the same manufacturing and scale-up questions. A second campus operates in Houston, placing it close to the energy industry.
Member companies have worked on long-duration energy storage, low-carbon materials, industrial heat, and grid infrastructure — categories requiring physical testing rather than software iteration.
The incubator's value is infrastructural: access to equipment that would otherwise consume a large share of an early climate company's capital.
