Meet the Team

A message from the CEO

In 2018, the Intergovernmental Panel on Climate Change issued a report that stated we have just 12 years to make massive and unprecedented changes to our economy to mitigate the effects of climate change and keep global warming to less than 1.5 degrees celsius. Only 12 years! Today, we have 10 years left to accomplish this extraordinary transformation across all sectors of our economy: energy, transportation, building systems, manufacturing, agriculture, and more. This is no small task and will take enormous effort, but I am—and the Greentown Labs team is—optimistic and believe this is a winnable fight. I believe because of the incredible entrepreneurs we’re proud to support at Greentown Labs, who are working diligently and passionately to develop solutions to these challenges. I believe because of our network of partners and investors who are embracing a leadership role in corporate climate action, increasing their efforts to procure renewable energy, and helping startups bring their technologies to market. I believe because of the climate and cleantech ecosystem across the country—and the globe—that’s committed to working hard today to create a better tomorrow for all of us. We’re eager to bring together communities from around the world to connect, convene, and collaborate on climate action. I hope you’ll join us!

Our Values

The Greentown team views driving climate impact through entrepreneurship, partnership, and collaboration as our North Star. To curate, support, and foster our community of startups and corporate partners in the name of climate action, we use the following values as our compass. 


We believe in transparency and integrity, and use these qualities as a guide in all of our communications, behaviors, and attitudes. We are open to diverse perspectives, community members, and partners, and seek them out as often as we can.


We follow the golden rule and treat others how we want to be treated. We are thoughtful, helpful, and kind to our colleagues, community members, and partners, and we treat them all equally.


We celebrate and acknowledge wins within our team and community—both big and small. We are empathetic and patient with our colleagues and our community members.


We hustle with purpose. We’re collaborative and pragmatic in our approach to pursuing new opportunities and solving big challenges.


We are driven by a passion for our mission and we subscribe to an optimistic mindset. We persevere in trying times with the grit of an entrepreneur.


We find humor and joy in our day-to-day operations and strive to create genuine camaraderie among our team. We welcome and encourage spontaneous team time amidst the buzz of our everyday activities.
