If you want to be a member at either Boston-area or Houston location of Greentown Labs, you better have a small carbon footprint.

Leading global venture capital firm Clean Energy Ventures, which funds early-stage climate tech innovations, announced a partnership to offer access to the firm’s Simple Emissions Reduction Calculator (SERC) to Greentown Labs, the largest climate tech incubator in North America that is dually located in Houston and Sommerville, Massachusetts. New members will be required to report their CO2e emissions reduction potential as part of the incubator’s climate impact assessment as part of the Greentown Labs’ application process.

Greentown Labs has nurtured more than 525 companies across its two locations with a 94 percent success rate for startups. Greentown Labs supports and fosters collaboration with corporates, early-stage entrepreneurs, investors, government and other players while providing members access to labs and resources.

“As we continue our work to support the most innovative climate tech startups, we’re doubling down on how we quantify impact — both the impact Greentown Labs is having on the entrepreneurs we’re privileged to support, and the impact the startups themselves are having by reducing greenhouse gas emissions,” Kevin Knobloch, CEO and president of Greentown Labs, says in a news release. “Having access to this timely tool that Clean Energy Ventures has created is elevating our recruitment efforts and helping us standardize how we quantify the projected impact of our member community.”

CEV developed SERC in 2021 to assist startups with tools and algorithms to estimate their technology or business model’s emissions reduction potential. SERC is now used as an essential screening tool in over 1,000 companies asn a climate tech accelerators, incubators and investors across the globe, and was awarded an honorable mention by Fast Company World Changing Ideas in 2022.

“As climate tech investors, we are always eager to support the growth of an ecosystem of innovation and impact,” CEV Managing Partner David Miller in says in the release. “With the number of climate tech companies seeking investments today, startups that are able to estimate their innovation’s capacity to mitigate CO2e emissions truly stand out from the crowd and are more likely to secure investment. Through SERC, investors are able to gain critical insight to back the most impactful technologies with the potential to address climate change as quickly as possible over the next two decades.”

Greentown Labs combines forces with MassChallenge to support more climate startups

strategic partnership

Climatetech incubator Greentown Labs has formed a strategic partnership with global zero-equity accelerator MassChallenge.

The two organizations have headquarters in the Boston area, while Greentown Labs is also co-located in Houston. MassChallenge has a hub in Dallas, as well as others in Israel, Switzerland and the United Kingdom.

The new partnership aims to strengthen the ecosystem for early-stage climatetech startups by providing more mentorship, support and a broader commercialization network for members, according to a news release.

Greentown Labs will share its expertise with the 23 startups in MassChallenge's first climate-specific accelerator, known as the MassChallenge Early Stage Climate program. Additionally, Greentown Labs members will benefit from MassChallenge's network of expert mentors, judges, entrepreneurs, partners, investors, philanthropists and others.

“There are so many synergies and shared values between MassChallenge and Greentown that launching a collaboration like this feels like a natural next step for our organizations as we strive to support as many early-stage climate founders as possible,” Georgina Campbell Flatter, Greentown Labs CEO, said in the news release. “We want to reduce the friction and barriers to market for these climate entrepreneurs and ultimately increase their opportunity for success—ecosystem collaboration is an essential part of solving these challenges together.”

Combined, Greentown and MassChallenge report that they have supported more than 4,500 founders and more than 1,000 climate startups. MassChallenge has awarded more than $18 million in equity-free grants to startups, which have gone on to raise over $15 billion, since it was founded in 2009. Greentown Labs has helped more than 575 startups raise more than $8.2 billion in funding since it launched in 2011.

Greentown recently added five startups to its Houston community and 14 other climatetech ventures to its Boston incubator. It also announced its third ACCEL cohort, which works to advance BIPOC-led startups in the climatetech space, earlier this year. Read more here.
